What are the symptoms of single-phase AC motor cable failure?

●Wire surface markings——According to the standard, the surface of the wire should have continuous markings of the manufacturer’s name, product model and rated voltage. This helps to find the manufacturer in time when there is a problem in the use of the wire, and consumers must pay attention to this when purchasing the wire. At the same time, when purchasing wires, pay attention to whether the manufacturer’s name, product model, and rated voltage of the single-phase AC motor indicated on the certificate are consistent with the printed logo on the surface of the wire to prevent counterfeit products.

●Appearance of the wire-When purchasing wires, pay attention to the appearance of the wire should be smooth and flat, the insulation and sheath layer should not be damaged, the logo printing should be clear, and the wire should not be greasy when hand-molded. 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 should not be eccentric, and the insulation or sheath should have a certain thickness.

●Conductor diameter—when purchasing wires, single-phase AC motor manufacturers should pay attention to whether the conductor diameter is consistent with the cross-section indicated on the certificate. If the conductor cross-section is too small, it is easy to heat the wire and cause a short Circuit. It is recommended to use wires of 1.5 square millimeters and above for household lighting Circuits; household appliances with high power such as air conditioners and microwave ovens should use wires of 2.5 square millimeters and above.

●Regular use-the wiring should be standardized, and the fixed line should use BV single-core wire to pass through the pipe. Be careful not to damage the wires when wiring, and do not damage the wires when decorating the room; do not connect in the middle of a route; the wires are connected to the electrical box (Box) do not touch the wire; in addition, household appliances with large power consumption, such as air conditioners, should be powered by a single wire; the wires for weak and strong currents should be kept at a certain distance.

Common faults in single-phase AC motor cable lines include mechanical damage, insulation damage, insulation damp, insulation deterioration, overvoltage, and cable overheating faults. When the above-mentioned 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 inspected and analyzed, and then repair and test should be carried out. The power supply can be restored after the removal of the fault.
