Parallel Groove Clamp

Parallel Groove Clamp connector is a conductor designed for the purpose of connecting two or more conductors whose axes are parallel to each other.

Parallel Groove Clamp also called PG Clamp are primarily intended to establish electrical connection between conductors, aluminium to aluminium or aluminium to copper or copper to copper conductors, between equipment and conductors, etc, in places like substations and generating stations.

As per IS 5561 : 2018 (Electric Power Connectors), originally IS 5561 : 1970. Our product also conform to ANSI/ NEMA CC1 : 2009 (Electric power connectors for substation), IEC 61284 : 1997 (Overhead lines — Requirement and tests for fittings, IS/IEC 62271 (Part 1) : 2007 (High-voltage switchgear and control gear — Part 1: Common specifications), IS 2121 (Part 4) : 1991 (Non Tension Joints – Specifications)

The rated normal current of PG clamp is ther.m.s value of the current which carry continuously under specified conditions of use and behaviour and can be selected from one of the following values:200 A, 400 A, 630 A, 800 A, 1000 A, 1250 A, 1600 A, 2000 A, 2500 A, 3000 A or 3150 A or as recommended by the conductor manufacturer.
