Ground pins, grounding rods, grounding wire insulation power specifications 10KV35KV220KV500KV

(1) high-voltage ground wire effect: high voltage lines and ground lines are used for substation construction, in order to prevent near the charged body to ensure the safety of the use or misuse of electrostatic induction shock when closing. ???? (2) high-voltage ground wire structure: carry-pressure ground wire from the insulated operating rod, wire clips, short routes, grounding wire, grounding terminals, bus clip, earth clamp. ???? (3) A ground wire production process: wire clip, earth clamp is made of high quality aluminum die casting; operating rod tube with epoxy resin color, good insulation properties, high strength, light weight, bright, smooth appearance ; ground high-quality multi-strand soft copper soft copper twisted together and covered with soft, transparent high-temperature insulating sheath can prevent the use of wear and tear on the ground copper wire, copper wire fatigue testing requirements to ensure that worker safety in operation. ???? (4) Grounding Specifications: ground wire in the power system: It is an important tool to ensure staff is on the device has power and voltage line appears unexpectedly. According to the ministerial regulations, ground must be more than 25mm 2 bare copper cord made. ? High-voltage ground wire resistance requirements:????? High-voltage short-circuit ground wire to ground resistance requirements determine the quality of the ground wire, generally in accordance with the power industry DL-T879-2004 technical requirements of each cross-sectional area of ??the ground wire to ground resistance is not greater than the following values:???? to measure the DC resistance between lugs, for 16mm2, various cross-sectional 25mm2,35mm2,50mm2,70mm2,95mm2,120mm2 average per meter resistance???????? value should be less than respectively 1.24mΩ, 0.79mΩ, 0.56mΩ, 0.40mΩ, 0.28mΩ, 0.21mΩ, 0.16mΩ. ???? High-voltage ground wire Classification (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 Technical parameters:???? (1) 10KV high-voltage ground wire insulated rod section Length: 700 mm Length of handshake part: 300 mm metal joint portion length: 50 mm Sessions: 1 Path: 30mm total length (excluding clip):??? 1050 mm (2) 35KV ground nominal cross section: 25mm2 total root number: 810 Average diameter (mm): 0.2mm calculated cross-section: (mm2): 25.43 metal joint portion length: 50 mm Sessions: 1 Path:??? 30mm (3) 110KV high voltage ground nominal cross section: 35mm2 total root number: 1136 average diameter (mm): 0.2mm calculated cross section: (mm2): 35.67 parts of insulating rod length: 1360 mm Handshake part of the length: 700 mm metal joint portion length: 140 mm section number : 2 Diameter: 30mm total length (excluding clip): 2200 mm use: (1) Articulated ground:????? first link grounding clip, followed by electrical connection clip; when removing the grounding line, you must press program to disconnect Clips, after the demolition earth clamp. ?? (2) Installation: on the ground soft copper phase is fixed to the ground rod eyes copper nose clip electrical connection (electrical connection clip fixed and movable type) corresponding position on the unilateral ground wire on the closing phase copper nose fixed on the ground folder or needle, constitute a complete grounding wire. ?? (3) Verify that the voltage level and the ground rod operation of the device are the same voltage level. ?? (4) took part in the ground soft copper phase and modular, ground rods have flat type and double reed hook clamp. ?? Contact: Ms. Sun Tel:?? 0311-87541961, 18830129079 QQ: 376635907
