Shear Bolt Connector

Copper Bolt Mechanical Lug

Short Description: Typical Application: LV & MV conductor connections for Cable terminations & Joints Mechanical connectors are designed for use in LV and MV applications. The Connectors consist of a tin-plated body, shear-head bolts and inserts for small conductor sizes. Made of special aluminium alloy, these contact bolts are shear-head bolts with hexagon heads. The bolts are treated with a lubricating wax. Both versions of contact bolts removable/ irremovable are available. The body is made of a high-tensile, tin-plated aluminium alloy. The internal surface of the conductor holes is grooved. Lugs are suitable for outdoor and indoor applications and are available with different palm hole sizes. Mechanical connectors for Straight & transition Joints are available as unblocked & blocked type. Connectors are chamfered at the edges.

Overview

Torque terminals are specially designed to handle the connection between wires and equipment.
The unique shear bolt mechanism provides a consistent and reliable stopping point. Compared with traditional crimping hooks, it is super fast and super efficient, and ensures a consistent predetermined shear moment and compression force.
The torsion terminal is made of tin-plated aluminum alloy and has an inner groove-shaped wall surface.
The notable feature is that it can save labor and enhance the electrical and mechanical performance.
▪ Material: tinned aluminum alloy
