Grounding box, cable link box with SVL
This products is suitable for the direct grounding of metal sheath for high voltage single core cable.
Cross bonding link box is used for cross interconnection of high-voltage single-core cable metal sheath, limiting over voltage applied to cable sheath and both insulated part ends of insulated joint, controlling induced voltage on metal sheath, reducing or eliminating ring current on cable sheath, increasing transmission capacity of power cable, avoiding oversheath breakdown, to ensure a safe operating for per cable. With stainless steel enclosure, link box could be filled by resin inside, at the main time, link box is volume-small, weight-light, installation-easy and limiter removable.
