Supply hand ground rod grounding wire to ground lightning ground wire length Ⅸ resistance is how much? Supply hand ground rod grounding wire to ground lightning ground wire length Ⅸ resistance is how much? Supply hand ground rod grounding wire to ground lightning ground wire length Ⅸ resistance is how much? Lightning Protection lightning protection measures as part of its role is to the lightning current into the earth. Mine buildings and electrical equipment is mainly used arrester (including lightning rod, lightning protection zone, lightning network and anti-lightning devices, etc.) at one end in contact with the protective equipment and the other end connected to the device, when the occurrence of direct lightning strikes, arrester Lightning lead itself, the lightning current through its deflectors and grounding device into the earth. Further, since the side effects of electrostatic induction caused by lightning, causing collateral damage in order to prevent such houses of fire or electric shock, usually have a metal device in the building, metal pipes and steel structure of the ground; lightning invade along the low voltage overhead lines houses, causing insulation breakdown electric equipment inside, resulting in a fire or electric shock casualties personal, so also will the line and the insulating porcelain iron feet grounded before the house. JDX series portable short-circuit ground wire is based on "live working portable earthing and grounding short circuit device" People's Republic of China power industry standard (DL-T879-2004), combined with the majority of electricity workers, ground butt enhancement requests, by the company research personnel and power system engineering and technical personnel to develop a new product. JDX series portable short-circuit ground wire in June 2000 by the Ministry of type testing safety equipment for Quality Supervision and Inspection and Testing Center, and all test items qualified. Structural features 1. By wire end clamp, short route, bus clip, ground wire, lugs, ground clamp or temporary grounding and ground operations rods and other components. 2. The wire terminal and the ground terminal clamp with high-quality aluminum die-casting, with matching metal fasteners are nickel plated. 3. Ground operating rod using advanced epoxy resin insulation performance and superb mechanical strength, glass fiber refining, while the installation of the operating handle silicone rubber sheath, firm and insulation is more secure and reliable. 4. Short line and ground line of high-quality multi-strand soft copper wire twisted together and covered with soft, transparent high-temperature insulating sheath can prevent the use of wear and tear on the ground copper to ensure workers in operation Security. 5. lugs and bus clip and grounding copper wire and outer sheath crimping new technology, flexible connection can effectively prevent the use of copper wire connections off shares, increase the reliability and service life of the grounding line. High-voltage ground wire Category: (1) high-voltage ground wire in accordance with the use of the environment can be divided into: indoor busbar grounding line (JDX-NL) and outdoor circuit-type ground wire (JDX-WS). (2) high-voltage ground wire in accordance with the voltage level can be divided into: 10KV ground wire, 35KV high-voltage ground wire, 110KV grounding line, 220KV high-voltage ground wire, 500KV high-voltage ground wire clamp, earth clamp is made of high quality aluminum die casting; operating rod epoxy color tube, good insulation properties, high strength, light weight, bright, smooth appearance; grounding soft copper multi-strand high-quality soft copper twisted together and covered with soft, transparent high-temperature insulating sheath layer, you can prevent the use of wear and tear on the ground copper wire, copper wire fatigue testing requirements to ensure workers safety in operation. http://www.anfangshebei.net/ need to contact me if you have, Pang, linked - Train - Electric - Tel: 1-3-9-3-1-19-0-3-1-8 buckle - Buckle: 1-1-6-9-2-8-4-2-9-9 supply hand ground rod grounding wire to ground lightning ground wire length Ⅸ resistance is how much?
