Equipment Connector or Terminal Pad Clamp

Definition
An Equipment Connector is a connector designed for the purpose of connecting the terminal of the equipment to the conductor(s). Terminal pad (or) Round terminal stud.

Application/ Useage
Equipment Connector also called Terminal Pad Clamps 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.

Relevant Standard
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), BS 159 : 1992 (Busbar and busbar connections), BS 3288-1:2014 (Insulator and conductor fittings for overhead power lines: Part 1 Performance and
general requirements) 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)

Rated Normal Current
The rated normal current of Terminal Pad is the r.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.

Material
