2021 China New Design Heavy Duty Wire Ties - The cable clamp has the function of fixing – Xinxing

The cable clamp has the function of fixing. The cable clamp disperses the weight of the cable and the thermomechanical force generated by thermal expansion and cold contraction onto each clamp to be released, so as to prevent the cable from mechanical damage. There are different methods for fixing the clamp under different environmental conditions.

The cable is mainly laid in the tunnel. The snake laying method is adopted, so the cable must be fixed flexibly. This is because when the ambient temperature and load current change, the thermal mechanical force generated by thermal expansion and cold contraction of the cable is large. If this thermal mechanical force is concentrated in a certain part, it will cause cable damage.

Cable fixing clips are widely used in high-rise buildings, subways, high-speed railways, tunnels, etc. they are generally used to fix 110kV and 220kV cables. Cable fixing clips are made of anti-corrosion aluminum alloy and can be installed on cable supports or walls. Fix the cable without damaging the cable. After the high-voltage cable is laid, install the cable fixing clamp to prevent the cable from sliding and crossing, with long service life and strong stability.
