In today's social life, people's dependence on electricity is increasing day by day, and the requirements for the security of power grid power supply are getting higher and higher, especially the higher requirements for urban power grids. Therefore, it is one of the timely and effective measures to replace bare wires with insulated cables in the power supply lines of the city network. At the same time, the fittings should also take corresponding measures to make them have insulating functions. There are two methods. One is to apply insulating materials and design new fittings with insulating functions. The second is to design an insulating cover for the hardware to achieve the insulating effect.

Use

NXL series wedge-type tension clamps are suitable for distribution lines of 10kV and below, to fix overhead insulated aluminum conductors or bare aluminum conductors on the insulators of corners or terminal tension rods, so as to fix or tighten the overhead conductors, insulating cover It is used together with the tension clamp for insulation protection.
