Overview

Description:

Preformed armor grip suspension clamp has the similar function as normal suspension clamp. It is used as the suspension of conductor and grounding wire, but preformed suspension clamps can not only protect the conductors but also reduce corona discharge greatly because of its smooth appearance. So It is specially suitable for high voltage over 220KV lines. Preformed armor grip suspension clamp is designed to reduce the static and dynamic stresses at the support point and is superior to armor + clamp combinations for protecting conductors from bending, compression stress and abrasion. In addition, the armor grip suspension double assembly is suitable for long transmission line over river and big line angle between 30 and 60.

According to function and applicable area, it can be divided into:

Preformed conductor suspension clamp

Preformed grounding wire armor grip suspension clamp

Preformed armor grip suspension single assembly

Preformed armor grip suspension double assembly

Preformed suspension clamps are composed by preformed wire, rubber pad, metal sheath, fixed blade, bolt nut and washers. Normally the preformed armor grip suspension clamps will be assembled with socket clevis, link plate and other clevis.
