Description

 

A Parallel Groove Clamp (PG Clamp) is a mechanical connector used in overhead power lines to join two conductors in parallel. It provides a secure and electrically conductive bond between aluminum or copper conductors without the need for cutting or splicing. These clamps are widely used in medium-voltage and high-voltage networks, particularly for tapping lines, grounding, and jumpers in industrial and utility electrical systems.

Designed for quick installation and long-term performance, parallel groove clamps are a crucial component in reliable electrical distribution and network maintenance.

PG clamp is known for parallel groove clamp, especially used in transmission line to hold transmission conductors in parallel.

PG Clamp provides secure holding support for transmission conductors. PG clamps and bimetallic PG clamps are manufactured from high strength corrosion resistant aluminum alloy and use hot-dip galvanized steel bolts and nuts and corrosion protected washers.
