Shear Bolt Lug Mechanical Lug

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
▪ Working temperature: -55℃ to155℃ -67 ℉ to 311 ℉
▪ Standard: GB/T 2314 IEC 61238-1

Features and advantages

▪ 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

Overview

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.

Contact torque bolt Made of special aluminum alloy, these contact bolts are hexagonal head double-shear head bolts. These bolts are treated with high-quality lubricant and equipped with a special contact ring. Once the bolt head is sheared off, these contact bolts cannot be removed. Plug-in Special plug-in, put in or take out to adjust the range of applicable conductor. These inserts all have longitudinal stripes and a positioning slot.

installation

▪ 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.

Torque terminal

The installation tools you required：
▪ Hexagon socket  in correct size of A/F
▪ Ratchet wrench or electric impact wrench
▪  Highly recommended use the fixture for supporting the cutting bolt  in case of conductor bending

Installation Guide

1.  Choose the correct size of the terminal according to the product selection guide. Check and verified it has the same wire size as which marked in the cable and the terminal.

unscrew the shearing force bolt till it has rooms for cable to insert

2. The conductor shear end uniformity.  the peel length of the conductor which should be cut referring to the recommending guide.

avoid to cut the conductor.

3.Inserting the conductor at the bottom of the torque terminal carefully.

4.Tighten the shear bolt, fixed the conductor to the terminal. the tighten the bolt  from 1-2-3

5. To tighten up the bolt by the ratchet wrench or electric impact wrench, put on the strength in order from 1-2-3, first alarming phase, to apply the torque 15N.m in order from 1-2-3.

to apply the torque 15N.m in order from 1-2-3 at second time, to apply the torque till the bolt head be cutted in order from 1-2-3 at third time.

Repeat the cutting process till all the bolts down, and must be cutted from 1-2-3. Make sure to fix the terminal in the cutting process.

Make sure has the enough torque, the battery is in high gear. check the cutting results and remove the lubricant oil remained.
