copper clad steel
We could customize ground rod according to the customers drawings or samples.
The pieces are adhered to melt, adding a filler material (plastic or metal), also melted, which has a lower melting point than the part to be welded. Regardless of the method used, always have the personal protective Grounding Observation Wellequipment, work in a safe place and have precautionary measures, both to safeguard the life of the technician and to ensure the protection of equipment.
Lead-free: They are specially designed to work with lead-free soldering, which guarantees good welding quality and is not harmful to health. They have the highest melting point (217 degree C) than conventional lead solder. The most commonly used metallic feedstock is tin-lead alloy, which melts at about 230 degree C.
The author is associated with a soldering tip manufacturing company for a long time.
Strong soldering: This method achieves temperatures up to 800 degree C.
Hot air: This is a type of welder in which hot air is used to melt the welding of electronic components, the hot air station is mainly used to disassemble or weld SMD type components.
Oxyacetylene soldering (with gasses to the torch): The heat supplied in this type of welding is due to the combustion reaction of the acetylene, which proves to be strongly exothermic at temperatures of the order of 3500 degree C
Arc soldering: It is a low-cost method, besides being of easy and quick use, which applies to all kinds of metals, with you, can obtain perfect results. The adjustable soldering stations contain a temperature control knob for the welder. As a fluxing material to cover surfaces and remove rust, you can use borax. When the pieces cool, they become a strong joint; however, not all metals can be alloyed to generate a bond, as the welds melt at lower temperatures than the metal pieces to be bonded. Each day, these processes are perfected, and we can discover new techniques that allow the process of joining metals to be faster, efficient and safer.
Types of soldering
Soft soldering: We can do it at temperatures below 400 degree C.
The soldering can be carried out through different methods, which will depend on the type of material that we use, the force between the joints, among others.
Elements of the soldering process:
What is a Soldering station?
It is the instrument that allows us to solder the different points of union existing in the electronic equipment, depending on the circuit in which you Ground Rod Accessories are work; you must choose an appropriate soldering station, as the excessive heat can damage the electronic components.
Pressure soldering: It is a cold welding, where the bond between metals occurs without heat input. Meanwhile, a gas torch provides the necessary heat for the joint. Also, you can use alloys of silver and tin or copper, and zinc. Through this article, the author has highlighted the soldering process, different types of soldering, and a soldering station .
The soldering process is fundamental for all types of work, from the construction of furniture to the manufacture of cars, aircraft, and boats.
Soldering is a manufacturing process that consists of molten metal that joins two pieces of metal. It can be very useful in applications where it is essential not to alter the structure or properties of the materials. This knowledge would be helpful for you while you will go for buying soldering tips for a soldering process.

. As the cable reel length longer than the cable length may reach several kilometers, so by allowing the nominal tension and bending China Grounding Rods Manufacturers radius of the limit, special attention in the construction and the occurrence of kink phenomena can not be yanked.2mm galvanized steel wire for hanging wire hanging cable. Then there plus access probe fiber plate, the purpose is to prevent blind spots is not easy to find near there. The fiber on the welding machine v-shaped slot, careful pressure on the optical plate and fiber fixture, set according to the length of optical fiber cutting position in the platen, close the draft shield, welding can be done automatically, in just 11 seconds.com
(3) fiber connecting the process and steps:
1 stripping cable and cable box fixed to follow.9mm (outer coating) fiber cut length only 16mm.
(4) fiber optic cable laying, the non-cable to play a small circle and fold, twist, and be equipped with a certain number of walkie-talkies, "the former left with, fiber optic cable on the shoulder" of the release cable method, can effectively prevent the occurrence of the back button, Note also that force uniform, traction cable to allow no more than 80% of the maximum instantaneous traction does not exceed 100%. The pulse width and choose a smaller size, but with the cable length to correspond with the coordinates line up reducing the blind spots overlap, the more accurate the smaller the width, of course, the curve shows the pulse is too small to appear after the noise, to be just right..
(2) the formation of a high-quality construction team.4. Otherwise, it may cause broken fiber roll core. . Preparation
(1) Check the design data, materials, construction tools and equipment are complete. Stripped of the fiber coating is very fragile, use heat shrink tubing, can protect the optical fiber splicing head. Field continuation box must be sealed to prevent the water. Different beam tube, the fiber in different colors separately, through the heat-shrinkable tube. Cable laying
(1) the same batch of fiber, which is basically the same mode field diameter, the fiber is disconnected at some point, between the two ends of the mode field can be regarded as consistent, so this break point in the welding can weld the fiber mode field diameter minimize the impact of loss.
2 splitting the fiber through the heat-shrinkable tube.1, the fiber splice
(1) the fiber splice. Standard troubleshooting using meters, the type of layer stranded cable, and a strand rate problem, and that is the length of cable and fiber length is not equal to the length of the fiber is about 1. With special strippers strip coating, then dipped in alcohol to clean bare fiber on the cotton cloth several times, hard to moderate, and then cut with a precision optical fiber cleaver, for 0. In determining the point of failure, if the cable length is not known in advance, can be placed automatically otdr, identify the failure point of the general location, and then on the Advanced otdr.
3 Open Furukawa s176 welding machine power source, use a preset program for 42 kinds of welding, and in use and after use to remove welding machine in the dust, especially fixture, the mirror and v-groove pieces of dust and fiber not.5 ~ 1m or so, this work is called "distribution plate. Then put in traction between the pulley rope, cable pulling rope tied traction head, with some traction to cable pole climbing shelves, hanging in the hanging line.
(2) overhead cable available 7 2. Multi-core optical fiber cable to different colors in the same bunch of tubes into a group, so more than one core cable where there might be several beam tube. These potential pitfalls. Thus, the optical fiber fusion complete. the last one is the green beam tube.25mm (outer coating) fiber, Cut a length of 8mm-16mm, for 0. So we must maintain a certain radius, where the laser transmission in the core, to avoid unnecessary losses. Wear a stainless steel hook and hang the hanging line. Also in the construction plans should also indicate on the welding position, when the breakpoint occurs when the fiber optic cable, easy to find instruments quickly break repair. So, before welding system according to the fiber and the operating wavelength to select the appropriate welding procedures. SpliceCommon type of cable has stranded, skeleton and central beam tube fiber optic cable, the color sequence is divided into core blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, blue, This is called a core of full-color chromatography, some cable manufacturers with "character" with a certain color chromatography.
(2) drawing the path construction plans. Hanging wire and cable to be well grounded, there must be mine, anti-electric measures, and earthquake, wind mechanical properties.com
3. Generally allowable cable tension is about 150 ~ 200kg, cable bend radius should turn fiber diameter greater than or equal to 10 to 15 times, the construction should be laying the bending radius greater than or equal to 20 times.com)
1. Not self-supporting steel hanging wire cutter, cable sag, force poor to withstand wind load, so commonly used hanging.(3) erection of two fiber optic connectors at best flat in terrain, geological, stable place to avoid the reservoirs, rivers, canals and roads, the best in the pole or pipe outlet, overhead pole cable connector should fall next to the 0.
2, the fiber tested
Optical fiber in the erection, welding testing is completed, the equipment used mainly otdr tester, with the Canadian exfo&earth wire Manufacturers39;s ftb-100b Chinese color touch screen otdr portable tester (dynamic range of a 32/31, 37. Cross-section of the cable is, the red optical beam tube as the first bunch of tubes, clockwise followed by a white, snowy white and white .
(3) overhead cable laying. catv use of conventional single-mode fiber and dispersion-shifted single-mode optical fiber, Wavelength 1310nm and 1550nm are also two. Be careful not to damage the beam pipe, stripping length to take 1m or so, wipe clean with toilet paper will ointment, cable penetration will continue box, be sure to compress the fixed wire, not loose. Overhead power lines hanging lines and the horizontal and vertical distance to more than 2m, the minimum height from the ground 5m, minimum distance from the roof of 1.
5 to place fiber.chinaopticcable. Use of overhead pulley laying cable car line in the frame bar and hanging pre-hung pulley (usually every 10 ~ 20m hung a pulley), the cable onto the pulley, cited under the pulley at the reduced sag, reduce tension suffered.
(2) fiber connecting the following methods: welding, active connections, mechanical connection three.
7 fiber plate fixed. To make cable break occurs again in the continuation should be in every hundred meters left a certain margin, margin length is usually 5% to 10%, according to the actual needs of the length of the order, and in the disc around the state. Overhead cable hanging there are three kinds: prop hanging wire hanging, hanging wire winding and # self-supporting. Open the windscreen, the fiber removed from the welding machine, and then heat shrink tubing on the bare fiber center, into the furnace heating. Micro-heater can be used 20mm and 40mm and 60mm heat-shrinkable tubing heat shrink tubing generally, 20mm heat shrink tubing to be 40 seconds, 60mm heat shrink tubing is 85 seconds. To test the accuracy, otdr tester pulse size and width to the appropriate choice, given the refractive index n according to the factory value of target setting. Fiber splice, should follow the principle is: the same number of cores, the same beam pipe of the corresponding color fiber optic butt, core number is not the same core sequence first, then the number of large, followed a few small core.
Optical fiber communication technology in the last 20 years, the rapid development of new technology, as large amount of information transmission optical fiber communication, and rate, and digital information, send a digital signal, thereby broad-band image signals, computer networking and other information transmission is possible. Cable hook spacing of 40cm, hook buckle in the direction of hanging line to be consistent, at each pole must be convex drip groove, each cable tray should be left at joints 3m rod length plus the margin, to continue case ground welding operation, and every few hundred meters to have a certain drive to stay.
4 making optical fiber end face. Good poles planted in the pre-numbered, draw the path construction plans, and describe each pole or underground pipe outlet pipe length and the number of poles, and set the margin need to stay out of the length and location.com. Will continue to splice a good optical disk drive, the disc fiber, the larger the disk radius circle, the greater the curvature, the smaller the loss of the entire line.5/35, 40/38 , 45/43db), can test the location of fiber break; fiber link of the whole loss; about the loss along the fiber length distribution; fiber splice point connector loss. Most of the use of welding in the project method. Fiber connecting principles to be followed are: core number equal to the same beam pipe of the corresponding color fiber optic butt, core number is not the same core sequence first, then the number of large, followed a few small core. Basis having set up fiber optic cable to determine the routing number along the laying order, and ensure that the front panel cable to the b-side, and after a cable connected to a side, thus ensuring the continuation of the fiber end when the two are basically the same mode field diameter, the splice loss values to a minimum. This efficient use of fiber optic cable length, a reasonable allocation to minimize the welding point.
6 out of the optical fiber furnace heat shrink tube. In order to avoid the cable placed in the middle of road, about 20m away from the pole at, the opposite direction to the erection of two, first set up the first half of the volume, in the later half of the volume optical cable from the drive down, press the "8" shaped manner on the ground, then laying.
8 seal and suspend. In addition, set up, turn the cable at the office or the more complex terrain should be specifically responsible, non-vehicle rolled.., Ltd
(1) fiber optic cable laying before the first of the route through which to do serious investigation to understand the local road construction and planning, as much as possible to avoid the ponds, the wheat field, gas stations, etc.5m. Criteria for determining the breakpoint, the breakpoint does not follow if the box office, near the splice box will open, connected otdr tester, test failure point the exact distance from the test point, the use of fiber optic cable on the meter scale is very easy to find fault ." Plate can be reduced with reasonable welding point.Loss measurement of optical fiber is very important, it is directly related to the quality of fiber-optic communications, and to detect possible point of failure.chinaopticcable. Plus, when laying aside the natural bend and a variety of lengths, including a variety of reserve into the hole bending, rod aside, the joint reserve at both ends, horizontal curvature increases, and other special reserve.
Cable construction can be divided into the following steps: preparation route works → → → Cable laying fiber optic cable connecting → project acceptance

Take small steps so that the seam is firmly pressed down.For all your fake grass requirements you have synthetic grass Gold Coast . Apply glue using a spatula or plastic gloves. Close the seams like a zipper and it should be pressed strongly.
Fake grass is extensively used outdoors as it offers an appealing look. In every corner along the edges, put ekki posts at every 2 meters, China Copper Clad Steel Manufacturers so that they are in level with the surface and help in fixing the fake grass and the geotextile. Also remember, the glue hardens fast. In case your garden has a level and solid base without moles, installing fake grass directly on the ground is possible. Allow overlap of 5 cm, when earth rod Manufacturers it is cut to size so that the excess is removable during the fake grass installation at the end. The advantage of a cement-sand base is that moles and weeds are totally eliminated. Installation places and details:
The fake grass best base is cement stabilized sand, this is not always essential. Ensure there are no tears, pits or irregularities in the paved surface. The right pile direction is pointing the place from where you look at the garden. You may cut the edges and cut diagonally to avoid fiber damage. Do not think twice to choose Soft fall Gold Coast.
Put tape beneath the seams. If not, the steps are:
Remove the top layer, smoothen and level it using sand for about 1. Applying much glue will leave residues throughout the seams and between fibers, so removing glue residues instantly is a must.
The cutting of fake grass mat is done using a sharp and strong knife. Conversely, a white geotextile is laid out with drainage studs. Now compact to finish the surface so that the fake grass installation may be done for your garden. Once the seams are closed, walk at least three times the complete length. However, the fact cannot be denied that it is not very easy to install fake grass.
Follow these steps and install fake grass in your terrace or garden.
Balcony / Roof terrace
Installing fake grass on a roof terrace or a balcony means it is imperative to have a good drainage system. Sprinkling water on the geotextile helps to stick to the base firmly and will not move even while unrolling the grass.. Mix the dual component glue using a rod mixer and distribute on the tape into smaller portions. It prevents weeds, distributes pressure and thus reduces noise if the subsoil is cement-stabilized sand.5 to 2 cm below the level required. This will ensure much glue is not applied.
After the geotextile is laid out, the fake grass mats may be unrolled. Firstly, to install fake grass, a stable and smooth based ensuring perfect drainage system is mandatory. This functions as a buffer when the temperatures are too hot and also work as a drainage mat. The best effect is attained as you look into a fake or artificial grass pile.
A geotextile is laid underneath the fake grass. Cut the geotextile to size, roll out and fix using nails to ekki posts
