Product Introduction
use:
When the load-bearing cable needs to be connected and broken strands need to be repaired, it is used to connect the two ends of the wire instead of the conventional copper stranded wire connector clamp.
structure:
composition:
The connecting strips of the copper load-bearing cable are treated with 2, 3 or 4 groups of copper-magnesium alloy pre-twisted wires, and the inner surface is sprayed with tin, zinc, and copper powder conductive sand;
Features:
In terms of mechanical characteristics, the connecting strip can completely restore the mechanical strength of the load-bearing cable, which can reach 100% of the calculated breaking force of the original load-bearing cable;
The material used is the same as the load-bearing cable to ensure better corrosion resistance;
The pre-twisted splice strip used for the copper load-bearing cable has good conductivity in the inner conductive sand, so the flow capacity of the copper load-bearing cable will not be affected after the connection. In actual operation, due to the effect of stretching, the electrical conductivity will get better and better.
The installation of the connection strip is quick, simple and convenient. Without any tools, one person can complete the installation with bare hands on site, and there is no need to carry bulky compression tools.
Light weight, full of flexibility, and strong resistance to vibration fatigue.
