EX

The EX – type Clamp is a bolted cross clamp and they are capable of making connections that are in-line or at an angle of 90° at either end of the clamp. A is designed to bolt onto a solid stem and B is designed to bolt onto stranded conductor.

EX – Clamps are generally only to be used in non-current carrying applications e.g. through connections on support post insulators, voltage transformers and surge arresters. Each half clamp is fitted with two independent clamping saddles.

These clamps are intended for use in conjunction with post insulators to support phase conductor bundles between items of outdoor high voltage apparatus.

They are of the bolted type designation for making connections between horizontal triple conductors and a single vertical stem. Provided that the clamp is applied correctly with reference to the current rating, this clamp can be used as a single tap off from a triple conductor bundle.
