Why short circuit of wire and cable, do these points to make the wire use for a longer time

Short circuit of electric wire often happens in our life. We will analyze the main causes of electrical short circuit from several aspects. If it can be avoided, we should try to avoid these situations to prevent short circuit of wires and cables.

The main factors of short circuit of wire and cable are as follows:

1, when the wire insulation deterioration or by high temperature, humidity or corrosion and lose insulation ability, it will cause a short circuit accident.

2. When the insulation wire is directly wrapped around the hook on the nail or wire, it is easy to receive rust corrosion and damage the insulation layer and form a short circuit because of friction or rust.

3. Due to improper installation or negligent construction, the insulation layer of wires and cables may be subject to mechanical damage and short circuit.

4, due to the influence of lightning and other overvoltage, electrical equipment insulation may be broken down and form a short circuit.

5. Because the rated voltage of the selected equipment is too high to meet the working requirements, breakdown and short circuit may occur.

6, due to not timely maintenance, conductive dust fiber into the electrical equipment, may also cause a short circuit accident.

7, due to lax management, small animals or planting plants may also cause short-circuit accidents.

8, in the installation and inspection work, may also be due to contact and operation error caused by short circuit accident.

These are the most important factors that lead to short circuit of wires and cables. When using wires, be sure to lay the wires in a place where the environment is dry and the temperature is cool, so as to maximize the safety of the wires. Such as some places need to wrap nails, please go to the market to buy wire special insulation nails, which can greatly reduce friction and rust corrosion degree, can greatly reduce the possibility of short circuit; In the construction, more can not be neglected, mechanical damage will cause a direct impact on the wire.

So be careful; In the rainy day, if it is just good in the process of laying, there is an immediate stop, authorized wire, so as not to wire water leakage and in the process of use should also protect the wire not to let it be struck by lightning, the consequences of direct damage to the wire. When electrical equipment in the home is to be replaced, it is necessary to buy new spare electrical appliances according to the voltage size of the family, so as to avoid voltage discrepancy, resulting in wire heating and short circuit. In daily life, don't forget to maintain the telecom slightly, so as not to cause lax management.

All kinds of animal gnawing situation, in addition to regular inspection, once found that the wire has signs of damage there is a timely replacement of the new wire, do not wait until the problem is found to order the wire, until this time has been unable to use electricity.

If you encounter a short circuit, you can consider the above factors and take corresponding measures. At the same time, reliable wire and cable products should be selected in the project construction. Ruiyang Group specializes in wire and cable 20 years of self-production and self-marketing experience, for all kinds of global projects to provide different wire and cable.
