Design Analysis Of Bolt-type Tension Clamps In Conductor Fixing Structures

The design of the bolted type strain clamp is highly targeted; the cable grooves arranged inside its clamp blocks are a crucial component of the overall structure, a feature clearly reflected in its actual construction. During assembly, the wire enters the wire clamp block along the wire groove and is kept in place by bolts and accessories.

The cable grooves are concave structures that match the geometry of the conductors. This design stems from the functional requirements of the dead end strain clamp as a tension-bearing component. Unlike traditional planar contact methods, the increased contact area between the grooves and the conductor helps distribute the pressure between the cable and the fittings.

Manufacturers typically set the groove dimensions and angles according to power system requirements, allowing the bolted dead end clamp clamp blocks to be quickly positioned in the field, reducing the number of adjustments required.
