Knowledge sharing about wires

Source : Tianxing Cable | Release date : 2024-05-06
Electricity, has become an essential part of our lives, the growing demand for electricity, so that people's requirements for the carrying capacity of the wire is gradually increasing, if the wire is not selected well, there will be a lot of accidents prone to danger, the following several knowledge about the safety of the wire, please take a good look.

Qingdao wire and cable manufacturers

1. The wire must be covered in the wire sleeve

If the wire is buried directly in the ground, there is a risk of leakage, and the wire is buried in the sleeve can play a protective role, and if there is a problem later, it is also easy to withdraw the wire for repair and replacement. And due to thermal expansion and contraction, the wall may have cracks and deformation, which may cause the wires in the wall to break, cause line failure, or leakage, electric shock accidents.

2. The insulation layer should be checked well

If you pull the wire by hand, the external insulation layer is white and cracked, it is likely to be poor quality wire, poor quality wire insulation layer is generally poor, and such insulation can play a limited protective role, it is likely to leak.

3. Select an appropriate square line

The load of different square lines is different, the load power is different, and the load of aluminum and copper lines is also different. High-power electrical appliances have different requirements for square lines. For example, if the air conditioner uses 6 square aluminum wire, it can load 10kw, and the total air switch in the home should use 63A rather than 40A of the general developer.

4. Detail processing of wire joints

Generally, the wire joint should be set aside a section of the wire first, and then wrap them around each other to ensure the normal use of the wire. If such an interface is not handled well, it is easy to have a power failure and leakage accident, which is to melt the tin wire with a soldering iron at the junction of the wire, and then wrap the wire joint with insulating tape.

5. Cable overload problem

The load of the wire increases, the wire will be overloaded and the temperature will rise, if it is so for a long time, the insulator of the wire will melt and bubble, and the conductor of the wire will be exposed, such as in wet weather, it is easy to short circuit the line, and it is easy to catch fire because of small Mars.

6. The flame retardant level is not in place

Once the wire encounters Mars or small sparks, the flame retardant level of the wire is not enough, then it is very easy to fire and the possibility of fire expansion is high, but the flame retardant level of the wire with CCC certification is generally qualified, so look for the wire with 3C certification. And more advanced fluorine plastic wire, such as special plastic king wire, flame retardant level will be higher than the certification, choose this kind of wire friends can be more at ease.

7. Check the wires regularly

After a period of time, the wire will age, and the outer insulation layer will fall off after aging, so that the wire is exposed, which will easily cause electric shock accidents or fires.

8. Identify fake and shoddy wires

Rough statistics from the fire department show that more than 40 percent of fires in recent years have been caused by electrical faults, and black wires with copper cores "shrunk" are one of the main causes. If the copper core of fake and shoddy wire does not pass, light may cause short circuit, electric shock, heavy may cause fire, causing casualties.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
