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.

Parallel Groove Clamps vs Compression Connectors

Feature Parallel Groove Clamp Compression Connector
Installation Tool-free or standard wrench Requires hydraulic crimping tool
Reusability Reusable Permanent once crimped
Application Speed Fast and easy field application Slower, especially in hard-to-access areas
Mechanical Strength High (multi-bolt options available) Very high
Best Use Temporary or semi-permanent connections Long-term, load-bearing connections

Parallel groove clamps are ideal for fast, safe, and efficient connections in expanding or reconfiguring overhead systems.
