Electric power fittings are accessories that play a role in transmitting and protecting electrical and mechanical loads in engineering. They are a general term for the combination components of power system connections. Suspension clamps play a role in fixing suspension cables in power construction. So, what are the specific tasks of suspension clamps? Let's take a look together!
Suspension clamp is a metal fixture used to suspend the tension and terminal pole of a straight pole or a suspension jumper insulator string supporting a stranded wire insulator string; During normal operation, it can withstand vertical loads but not tension from stranded wires, and can be used in conjunction with connecting fittings. The insulator string and wire connection are suspended together on the pole cross arm; The design of suspension clamps can reduce the impact of vibration on wires and ground wires, and avoid damage caused by stress concentration between wires and ground wires. When installing suspension clamps, the bracket is fixed on a fixed object (pole or tower), and then an insulation block is clamped on the cable. The cable and insulation block are then installed into the bracket together. There should be sufficient contact surface between the suspension clamp and the installed wires and ground wires to reduce damage caused by fault currents.
The suspension clamp can adapt to natural environments and is not affected by natural climate and environmental factors. It mainly bears vertical loads, wind loads, and frictional forces between the conductor and the contact surface; The use of suspension clamps can reduce the stress on cables at suspension points, while also controlling the stress of wind induced vibrations and assisting in cable damping, thereby better protecting cables
