Double tongue grounding rod
The main components of the product by the cable to the hook line, or the busbar flat clamp, shorted to the grounding line grounding wire, wiring nose, manifold, grounding terminal clamp or five anti-locking chuck, grounding steel fiber and grounding rods, etc. composition. The clip is made of high-quality hot copper (or ripe aluminum), and the wire is the important part of the portable short-circuit grounding wire. The short-circuit and grounding rods produced by our factory are more technical than the similar products in France. Products, high and low voltage power transmission lines and electrical equipment maintenance of the power to provide a reliable security protection. Grounding rods with mechanical strength, excellent insulation properties of imported glass fiber epoxy resin tube according to the type of demand for preparation
Portable short-circuit ground wire is divided into two types of phase and combined. Applicable voltage: 500V, 10kV, 35kV, 110kV, 220kV, 500kV and so on. Applicable to power plants, power supply, telecommunications, railways, subway and other substation users and construction units, at the same time can be customized according to special specifications ground wire.
Before using the portable short-circuit ground wire, it should be confirmed by power failure before power failure, after confirmation of no voltage on the device. First connect the grounding clamp to the grounding wire or flat iron, and then tighten the wire end to the device wire with the grounding rod. When removing the short-circuit ground wire, the sequence is just the opposite.
Installed short-circuit ground wire, it and the distance of live equipment, taking into account the impact of grounding pendulum, the safety distance should not be less than the "power safety work order" the new provisions of the value.
It is strictly forbidden to use the winding method to ground short circuit without using clamp.
If the grounding point of the hanging point, the application of grounding or special copper rod for ground connection; if no fixed grounding point available; can be temporary grounding point, ground buried depth of not less than 0.6m.
Portable short-circuit ground wire should be kept safe. Before each use, should carefully check whether it is intact, soft copper wire naked, the nut is not loose, or shall not be used.
Portable short-circuit ground wire inspection cycle for every five years, the same test items with the factory inspection. Tested qualified portable short-circuit ground wire after undergoing short-circuit, should be subject to short-circuit current size and appearance of inspection to determine the general should be scrapped.
Copper for the production of high-quality electrolytic copper materials.
