Import Bare Copper Ground Wire — Buy in wholesale FOB from Supplier in China

Henan Yubian Electricians Co., Ltd. produces bare copper ground wire from electrolytic tough pitch copper rated at Cu 99.99%, manufactured at its facility in Qianlong Industrial Park, Huixian City, Henan Province, China. The product is configured for 10 kV outdoor power transmission line grounding, with a screw-press flat-opening electrical clamping system designed to bridge a 35 mm gap at maximum opening. The standard wire diameter is 25 mm, supplied in a 3 x 1.5 m plus 12 m configuration, though dimensions can be customized to user requirements. This specification targets utility maintenance crews and electrical contractors requiring portable grounding sets for live-line work.

The ETP copper material offers electrical conductivity typical of pure copper, approximately 100% IACS, with excellent work hardening characteristics that maintain clamp contact pressure through repeated use. The screw-press clamp mechanism with flat-opening jaws provides secure attachment to buswork or conductors without threading, a critical safety feature for temporary grounding during line maintenance. The lever assembly uses three 1 m lengths of 30 mm outside diameter tubing, with lever length and diameter customizable. Ground wire flexibility and current-carrying capacity depend on the actual cross-sectional area, which buyers should verify against their system's fault current magnitude and duration.

Applications center on 10 kV distribution network maintenance, including temporary protective grounding of de-energized lines during repair or construction. The product serves State Grid and Southern Power Grid contractors in China, as well as export markets requiring IEC 61230 or equivalent portable earthing equipment. Voltage grade, specific environmental conditions, and fault level determine the correct configuration of ground rod length, clamp type, soft copper wire thickness, and grounding method. Buyers must confirm these parameters with Henan Yubian before ordering, as the same voltage grade demands different configurations under varying use conditions. Pricing, MOQ, and standard lead time are not specified and require direct supplier confirmation.
