Bolt Type Torque Terminal

Bolt type torque terminal is an electrical connection device that combines mechanical fastening and torque control technology, mainly used for efficient and safe connection of cables and equipment. Its core technology and application characteristics are as follows:

1、 Definition and core functions

1.1 Structural composition: It is usually composed of high-strength aluminum alloy body, mechanical shear bolts, sealing components, etc. Some products are formed by forging aviation 7 series aluminum alloy, and the surface is treated with tin plating to improve oxidation resistance.

1.2 Torque control mechanism: The shear bolt with preset installation torque automatically fractures when the torque value is reached, ensuring installation accuracy and consistency, and avoiding manual operation errors.

2、 Technical features

Installation convenience

2.1 Only ordinary wrenches or socket tools are needed to complete the installation, without the need for specialized crimping equipment or complex skills.

2.2 The installation is completed by indicating the breakage of the shear bolt, which is intuitive and reliable.

Materials and processes

2.3 High strength aluminum alloy (such as 7 series) or special alloy is used, which has good conductivity and mechanical strength, and is compatible with copper, aluminum, and aluminum alloy cable connections.

2.4 Sealing design (such as sealing strips, joint compounds) prevents moisture and dust from entering, extending the service life.

Performance advantages

2.5. The contact surface is cleaned of oxides by grinding particles to maintain low contact resistance.

2.6 Elastic structure offsets thermal expansion and contraction stress to prevent wire loosening.

3、 Application scenarios and specifications

Applicable scenarios: in the fields of power equipment, distribution systems, photovoltaics, etc., supporting cable connections with voltage levels of 35kV and below.

Specification range: The cross-sectional area of the wire covers 6mm ² to 1500mm ².
