Product Details

It is composed of insulating operating rod, wire clamp, short-circuit wire, grounding wire, grounding terminal, bus bar clamp, grounding clamp, etc. The wire clamp and grounding clamp are made of high-quality aluminum alloy die-casting, with high strength, and after surface treatment, the surface of the clamp is not easy to oxidize. The operating rod is made of imported epoxy resin into a colorful tube, with good insulation performance, high strength, light weight, bright colors, smooth appearance, and exquisite workmanship. It is a technical product in the same manufacturing field.

Technical Parameters:

(1) 10KV High-voltage Grounding Wire: Insulating rod length: 700 mm, handle length: 300 mm, metal joint length: 50 mm, number of sections: 1, rod diameter: 30mm, total length (excluding clamps): 1050 mm

(2) 35KV Grounding Wire: Nominal cross-section: 25mm2, total number of strands: 810, average diameter (mm): 0.2mm, calculated cross-section (mm2): 25.43, metal joint length: 50 mm, number of sections: 1, rod diameter: 30mm

(3) 110KV High-voltage Grounding Wire: Nominal cross-section: 35mm2, total number of strands: 1136, average diameter (mm): 0.2mm, calculated cross-section (mm2): 35.67, insulating rod length: 1360 mm, handle length: 700 mm, metal joint length: 140 mm, number of sections: 2, rod diameter: 30mm, total length (excluding clamps): 2200 mm

 

Precautions:

 1. If there is no fixed grounding point available at the suspension point of the FDB-B/C/D220KV Short-circuit Grounding Wire, a temporary grounding electrode can be used as a temporary grounding point. The buried depth of the grounding rod should not be less than 0.6M.

2. The flat-mouth spiral compression short-circuit grounding wire should be stored in a dedicated location with air circulation and dry environment. Before each use, it should be carefully checked for integrity. If the clamp is cracked, the connection is loose, the protective layer is damaged, or the soft copper wire is exposed, it should be prohibited from use.

 3. Regular inspections should be carried out in accordance with the requirements of the electrical safety work regulations (inspection items are the same as factory inspection).

4. After passing the test, the flat-mouth spiral compression short-circuit grounding wire should generally be scrapped after experiencing a short circuit.
