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.

▪ Wide range of applications
▪ Compact design
▪ It can be used with almost all types of conductors and materials
▪ Constant torque shearing head nut guarantees good electrical contact performance
▪ It can be easily installed with a standard socket wrench
▪ Pre-engineered design for perfect installation on medium voltage cables up to 42kV
▪ Good over-current and anti-short-term current impact capability
The terminal body is made of a high-tensile tin-plated aluminum alloy. The terminal is suitable for outdoor and indoor applications, and can provide different size specifications.
Features and advantages of mechanical lugs and connectors | Function |
Wide application range and strong versatility | For example, three specifications can cover 25mm2 to 400mm2 conductors. |
The body is made of high-tensile tinned aluminum alloy | And it can be used with almost every type of conductor and material. |
The bolts are made of special aluminum alloy | Good contact characteristics, can realize the connection between the copper conductor and the aluminum conductor. |
Compact design | Only need a small installation space, especially suitable for large-scale applications. |
Tubular spiral design inside the body to improve contact performance | Excellent electrical performance. |
Centering hole and insert | The conductor oxide layer is split. |
Constant torque shear head nut | The plug-in piece adjusts one size of the connection or terminal suitable for more types of wires. |
Lubricated nut | The inserts help the conductor to be better centered and will not deform the conductor when the bolt is tightened. |
Special features of mechanical terminals | |
Long handle | With extra long length, it can be used as a moisture barrier |
Horizontal sealing is suitable | Suitable for indoor and outdoor applications |
▪ No special tools are required for installation, only a socket wrench is needed for installation;
▪ Each type uses the same reduced length, including the provision of inserts;
▪ Hierarchical fixed torque scissor head nut design to ensure reliable and firm contact;
▪ Each connector or cable lug has a separate installation instruction;
▪ We recommend using a support tool (see attachment) to prevent the conductor from bending.
