Wire surface marking - according to the national standard, the wire surface should have the manufacturer name, product model and rated voltage continuous marking. This is conducive to finding the manufacturer in time when problems occur during the use of wires, and consumers must pay attention to this when purchasing wires. At the same time, consumers should pay attention to whether the name of the manufacturer, product model, and rated voltage indicated on the certificate are consistent with the printed mark on the surface of the wire, so as to prevent counterfeit products.

Appearance of wires - Consumers should pay attention to the appearance of wires when purchasing wires, the appearance of wires should be smooth and flat, the insulation and sheath layers should not be damaged, the logo printing should be clear, and there should be no greasy feeling when hand-molding wires. From the cross-section of the wire, the thickness of the insulation or sheath should be uniform on the entire circumference of the wire, and the insulation or sheath should not be off-core, and the insulation or sheath should have a certain thickness.

Conductor wire diameter - consumers should pay attention to whether the conductor wire diameter is consistent with the cross-section indicated on the certificate, if the conductor cross-section is small, it is easy to cause short circuit due to wire heating. It is recommended that the wires for household lighting lines should be 1.5 square millimeters and above, and the wires of 2.5 square millimeters and above should be used for household appliances with large power such as air conditioners and microwave ovens.

Standardized use - the wiring should be standardized, the fixed line is best to use BV single-core wire through the pipe, pay attention not to touch the wire when wiring, do not touch the wire when decorating the room; Do not have a joint in the middle of a course; Do not touch the wire when connecting to the electrical box (box); In addition, household appliances with large electricity consumption, such as air conditioners, should be powered by a separate wire; It is best to keep a certain distance between the wires used for weak and strong currents.

Common faults in cable lines include mechanical damage, insulation damage, insulation moisture, insulation aging and deterioration, overvoltage, cable overheating fault, etc. When the above fault occurs in the line, the power supply of the faulty cable should be cut off, the fault point should be found, the fault should be checked and analyzed, and then repaired and tested.
