Measures to Prevent Short-circuit of Flexible Cables

Measures to Prevent Short-circuit of Flexible Cables

Flexible cable is a very important cable, which is widely used in the power industry. When using flexible cable, you should pay attention to some methods to prevent cable short circuit. To a large extent, it can improve the efficiency of cable use. 


Ⅰ. Methods to prevent short circuits in flexible cables

1. Avoid distortion


Flexible cable is a very soft wire, so avoid twisting it as much as possible when using it. During the twisting process, the cable inside may break, which may cause a short circuit problem, so don't over-twist it. This requires special attention.


2. Choose the right type


When installing, repairing, and maintaining, choose suitable wires and cables according to the actual situation. In different places of use, in different power system links, the types of flexible cables used may be different, and the installation methods or accessories used are also different, so you need to strictly follow the power regulations.


3. Daily maintenance


We must always pay attention to strengthening the maintenance and management of flexible cables. It is necessary to carry out strict and detailed training for the personnel who specialize in managing and using flexible cables. It is necessary to reduce the factors considered to be damaged as much as possible in the normal management and use. In addition, it is necessary to frequently use the meter to measure the insulation degree of the cable.


4. Safety protection device


To choose a suitable safety protection device, configure a high-quality safety mechanism, and use a fuse for circuit protection, the rated current of the melt needs to be less than 2.5 times the long-term allowable load current intensity of the cable, so that the fuse can be realized more efficiently The value of the device to protect the circuit.


Ⅱ. Precautions for flexible cables

If the flexible cable circuit has automatic protection measures turned on, the instantaneous current should be less than 4.5 times the long-term allowable load current of the cable, which should be adjusted correctly during installation. It should also be noted that the fuse is installed on the lead, not on the neutral wire of the transformer.
