SJL Series Grounding Block – 100A Max Current Copper Alloy Grounding for Transmission Lines
Product Overview
The SJL series Grounding Block is a critical component for electrical safety in power distribution and transmission systems. Designed to create a permanent, low-resistance connection between grounding conductors, ground rods, and equipment frames, it ensures that fault currents have a safe path to earth. Constructed from high-conductivity casting steel and copper alloy, the grounding block provides 100A maximum current capacity and features a robust design for long-term reliability. Available in models for Φ38 and Φ48 conductors with bottom diameters of Φ46mm and Φ56mm respectively.
