The load is also called "overload". Wires also have their own power regulations. If it is overloaded, the thin wire can cause a fire by passing a large current. Indoor installation of open line, the ambient temperature should not be higher than 35 °C. Use wires in the safe current carrying of the wires so that the wires do not overheat. However, when the power consumption exceeds the safe current carrying capacity of the wire, the wire will heat up. The heat generated by the wire is proportional to the square of the current intensity. If the current intensity is increased by 2 times, the heat is increased by 4 times than the original, which will cause the wire to overheat and easily Causes a fire.

负荷也叫"过载"。电线也有它的载电规定。如果超负荷使用,细电线通过大电流,就容易引起火灾。室内安装明线,环境温度不应高于35℃。在电线安全载流内选用电线,电线不会发生过热。但用电量超过电线的安全载流时,电线会发热,电线的发热量和电流强度的平方成正比,如果电流强度增加2倍,发热量就比原来增加4倍,会造成电线过热,容易引起火灾。



The main reasons for the overload of the wires are:

电线超负荷的原因主要是:



1. The new line selection line is too thin and the section is small;

1、新线选线太细,截面小;



2. Add any load on the old line;

2、在旧线上任意增加负荷;



3. The fuse is not properly selected. The fuse is finely selected, often power off, which is not conducive to power supply; the fuse is thickened, the fuse is constantly overloaded, causing overheating to burn the wire insulation layer, and is also prone to fire.

3、保险丝选用不当。保险丝选细了,经常断电,不利于供电;保险丝选粗了,超负荷时保险丝不断,造成过热烧坏电线绝缘层,也容易引起火灾。



Wire maintenance attention to seven major issues

电线保养注意七大事项



1. Do not get wet, exposed to heat, corroded or bruised.

1、电线不要受潮,受热,受腐蚀或碰伤。



2, the wire used to a certain number of years to pay attention to inspection, found faulty, should be replaced in time.

2、电线用到一定年限要注意检查,发现毛病,应及时更换。



3, the wire should not be overloaded.

3、电线不要超负荷使用。



4. Always check the use of electrical and wiring in your home and carry out maintenance and overhaul in a timely manner.

4、经常检查家中电气和线路的使用情况,及时进行维护和检修。



5. For the lines of old-fashioned buildings, it is found that it is submerged or wetted by water, especially if the line is old and disrepaired, it should be immediately repaired by an electrician.

5、对于老式建筑的线路、发现被水淹没或淋湿,特别是线路年久失修发生老化的应立即请电工予以抢修。



6. For lines that are easily immersed in floods, the electrician should be asked to move the line and take elevated and moisture-proof measures.

6、对于容易被洪水浸泡的线路,应请电工迁移线路,采取高架、防潮措施。



7. If there is a power outage on a rainy day, the power should be cut off immediately. Ask the electrician to check the cause and send someone to take care of it.

7、雨天如停电应立即切断电源,请电工检查原因,并派专人加以看护。
