Product Description
Hook Type Grounding Block for Conductor Stringing – Eliminate Induced Electricity 100A
Product Overview
The SHL750D Hook Ground Block is a specialized grounding device designed for transmission line stringing operations. Its primary function is to remove induced electricity from the conductor or earth wire during stringing, protecting personnel and equipment from electrical shock. Featuring a triple sheave mechanism that is automatically compacted by torsion spring, the block provides reliable grounding contact. The maximum allowable current reaches 100A with a transit time of only 0.1 seconds. The recommended supporting earth wire cross-section is 25mm².

Applications
· Mount on outlet side of tensioner or inlet side of puller
· Eliminate induced electricity from conductor or earth wire
· Transmission line stringing safety grounding
· Temporary grounding during overhead line construction
Product Advantages
· Triple Sheave Mechanism — Three sheaves automatically compacted by torsion spring ensure reliable grounding contact with the conductor.
· Fast Current Transit — 0.1 second transit time rapidly diverts fault current, providing critical safety margin.
· 100A Current Capacity — Rated for 100A maximum current, suitable for transmission line induced current dissipation.
· Lightweight Design — At only 4.6-5.7kg, easily portable and installable by a single worker at height.
