BSM Series Aluminum Shear Bolt Connector

BSM connectors consist of a tin-plated body,shear bolt heads and inserts for small conductor sizes. Made of High-strength special aluminum alloy, these contact bolts are double shear bolt heads with hexagon heads. The bolts are treated with a highly lubricating agent. Contact bolts are irremovable once their heads have been sheared off. The lug body is made of a high-tensile, tin-plated aluminium alloy. The internal surface of the conductor holes are grooved.

Detail

Torque Splice Tubes are specifically designed to handle connections between conductors and equipment. The unique shear bolt mechanism provides consistent and reliable stops. It is ultra-fast and ultra-efficient compared to conventional crimp hooks and ensures consistent predetermined shear torque and compression. Torque splice tubes are constructed of tin-plated aluminum alloy and feature internally grooved walls. Notable features include the ability to save labor and enhanced electrical and mechanical properties.

● High-strength special aluminum alloy with a copper and tin-plated surface treatment to enhance conductor applicability performance
● Torque bolts: CNC lathe machined for higher precision and easy installation with only a handful of hexagonal bolts.

Component

Main body: special aluminum alloy material, forging process, surface tin plating treatment, plating layer> 7μm
Torque bolt: processed by CNC lathe, with higher precision
Intermediate baffle: The product is divided into oil blocking type and non-blocking type. Only the oil blocking type has a baffle.
Beading: starting from BSM-500/630, the connecting pipe does not have beading

Structural Features

▪ Wide application range: suitable for wires from 10mm² to 1000mm², and can be used with almost all types of wires and materials;
▪ Pre-construction design: perfectly fit for heavy-duty cable accessories up to 42KV;
▪ Reliable electrical connection performance: use the set torque screw to press the conductor into the inner bolt of the wiring tube;
▪ Easy installation: compact design, easy to install with standard socket wrench;

Installation

No special tools are required;

Only one socket wrench is required to complete the installation;

Including proving a tab;

The graded torque-double scissors head bolts are designed to ensure reliable and secure contact;

We recommend the use of a support tool (see accessories) to prevent bending of the conductor;

Each connector head or cable lug has a separate mounting instruction.

How To Cut Cables Correctly

When installing the splice connector, be sure to insert the wire completely into the tube hole: there is no gap between the cable and the splice connector
