Preformed dead end tension clamp has many types; it is normally used as assembly of transmission line bare conductor and covered conductors. It can replace the current bolt type clamps and compression type dead end strain clamp. Preformed tension clamp is usually made of aluminum clad steel, aluminum alloy, copper covered steel and galvanized steel. Preformed dead end clamp has firm preformed parts and can provide enough clamp strength to ACSR, AAC, AAAC, copper conductor and steel wire and have bigger suitable conductor size.

Features:
1. The stress of the suspension point is dispersed throughout the length of the pre-twisted wire, which effectively reduces the dynamic stress caused by the static stress and the breeze vibration of the wire, and avoids damage to the wire.

2. The stress concentration of the suspension point greatly improves the fatigue resistance of the wire and prolongs the service life of the wire.

3. Pre-twisted wire can provide reliable grip and withstand high unbalanced loads to avoid wire slippage.

4. special structure, can reduce electromagnetic loss and eliminate corona discharge, compared with the traditional suspension clamp has obvious energy-saving characteristics.

5. The rigidity of the wire hanging point is enhanced, and the radius of curvature is increased. The single-point point clamp can reach a steering angle of 30°, and the double-point line clamp can reach a steering angle of 60°.

Ordering Detail:
1. Please specify the wire type specification when selecting.

2. When the steering angle is between 30° and 60°, or in a large span project, the double fulcrum suspension clamp is directly connected to the insulator string.

3. Workers who have to be trained can install this product.

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.
