There are many types of power fittings manufacturers, which are known to the electric power industry. The cross arm is a kind of fittings commonly used in the power industry. It bears the tension of the wire, the force generated by the vertical load and the horizontal load, and its main function is to transmit Used to fix insulators to connect fittings, wires, etc. in electrical circuits.
There are two types of wire cross arm: fixed cross arm and rotating cross arm. Door-shaped linear rods or single-pole linear rods with smaller conductor grades all use fixed cross arms. The fixed plane cross arms are composed of angle steel plane racks and round steel booms. The cross arm plane bears the force generated by the breaking tension and vertical load. The rod bears the force of the vertical flat load; the plane cross arm is divided into two types, the pointed top and the flat top cross arm. The pointed top is used for straight rods, and the flat top is used for tensile rods. The installation process of the cross arm requires an electrician to manually operate it, so it is a basic requirement to protect the electrician from electric shock accidents. So how can we prevent the electrician from getting an electric shock when installing the electric hardware manufacturer's cross arm?
First, the anti-shock control of the circuit breaker, isolating switch or drop-out fuse on the stop column:
1. Wear insulating gloves and use qualified insulating rods during operation;
2. Insulating rods with rain cover should be used for rainy operations;
3. During pole-climbing operation, when there is a live low-voltage line on the same tower, the human body and the live body should be kept at a distance of 0.4 meters;
4. It is strictly forbidden to cross or touch low-voltage wires.
Second, the anti-electric shock measures during the switching operation:
1. It should be carried out by two persons, namely one person for supervision and one person for operation;
2. Switching operation is strictly prohibited when there is lightning.
