According to the requirements of the national industry standards, the wire surface should have continuous labeling of the manufacturer's name, product specifications and rated current. This is beneficial in the whole process of wire application problems can immediately find the production plant, customers try to pay attention to this when buying wires. At the same time, customers should pay attention to the manufacturer name, product specifications, rated current marked on the certificate and the packaging and printing mark on the surface of the wire are consistent to avoid counterfeit goods.



Wire appearance - When purchasing wire, customers should pay attention to the appearance of the wire should be smooth and smooth, the insulation layer and the protective sheath layer are not damaged, the mark is clear, and the hand model wire is not greasy. From the cross-section of the wire, the wall thickness of the upper insulation layer or wire sheath of the wire should be symmetrical, and the core should not be deflected, and the insulation layer or wire sheath should have a certain thickness.

Electric conductor cable diameter - Customers should pay attention to whether the electric conductor cable diameter is consistent with the clear cross section of the certificate when purchasing the wire. If the cross section of the electrical conductor is small, it is very easy to make the wire hot resulting in short circuit fault. Qingdao wire and cable manufacturers propose to use 1.5 square wires and above specifications for home lighting route wires; Central air conditioning, microwave oven heating and other electrical products with relatively large output power should use 2.5 square wires and above specifications of the wire.

Standard application - Should be standard wiring, fixed fixed route is to use BV single copper core cable through the pipeline, pay attention to do not damage the wire when walking, do not damage the wire when decorating the house; No connection head is necessary in the middle of a line; Do not touch the wire when connecting the home appliance box (box); In addition, electrical products with large power consumption, such as central air conditioning, should be distributed independently by one wire; The wires used for weak current installation are maintained at a certain distance.

Common faults of cable lines include mechanical damage, insulation damage, insulation moisture, insulation aging deterioration, overvoltage, and cable overheating.

When the route produces the above common faults, the switching power supply of the common fault cable should be disconnected, the common fault point should be found, the fault should be inspected and analyzed, and then the repair and experiment should be carried out. The excised section can be repaired after the common faults are removed.

Through the above introduction, I believe that everyone has a bottom in his heart, we usually use the household wire, we must choose wire and cable according to their actual needs. The correct selection of safe cables is the first consideration.

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.
