The service life of wire and cable
The service life of the wire needs to check the aging degree of the wire. If you do not use high-power electrical appliances for a long time, they can generally use them for 20 to 30 years. However, if you often use high-power electrical appliances, the power cord's safe current will exceed the safety current and cause heat and aging. , It can be adequately replaced. It has nothing to do with the thickness of the power cord.
The wire diameter of the power cord and the electric meter should match the electrical appliances' total power in the home. The electric meter is 8A, which allows electrical appliances within 1760 watts to be used. Of course, it is smaller if you use high-power electrical appliances. It is recommended to replace the meter and the power cord according to the power cord's thickness (high-power electrical appliances can use another dedicated line).
This depends on how thick the wire is used, whether the wire is protected by a conduit, and whether it is overloaded. Generally, it is a house like a community because it is an electrician. The line is more reasonable and the cable used is more appropriate. It takes a long time. As long as the house is not broken, there will be no human-made destruction. It is not a problem to use it for six to seventy years. The household wire socket's cross-sectional area needs to be more than square millimeters to meet the load. The household wire is well protected, and it also meets the conditional use requirements so that it can be used for a long time.
Principles of cable selection
Wires and cables are commonly used in daily life. When selecting wires and cables, consider the purpose, laying conditions, and safety.
1. Look at the usage
According to different uses, power cables, overhead insulated cables, control cables, etc. can be selected
2. Construction and laying environment
According to different laying conditions, general plastic insulated cables, rubber insulated cables, steel tape armored cables, steel wire armored cables, anticorrosive cables, etc. can be selected;
Three, look at the safety requirements.
According to safety requirements, flame-retardant cables, halogen-free flame-retardant cables, fire-resistant cables, etc., can be selected.
4. Large load capacity
Wires with solid load capacity:?The electricity consumption in the home is sometimes large or small. When it is large, we will turn on the TV, turn on the air conditioner, turn on the computer, turn on the light, turn on the water dispenser, refrigerator, hairdryer, etc. If the wire's load capacity is not strong, coupled with the hot summer, it is easy to cause the wire to burn due to the high temperature and cause a fire.
