How to correctly select wires and cables for the popularization of Zhujiang Cable Factory

Faced with many manufacturers and brands, how do customers choose wire and cable products? This is an easy task for professional electromechanical and electrical engineers. But for many ordinary users, as well as those who have just entered the industry, they need to understand.

When purchasing, you should choose the appropriate wire according to your own electricity load, and also look at the raw material composition, model specifications, etc. introduced in the wire and cable manual, so as to reduce the occurrence of safety hazards and also make the lifespan longer. . Specifically, there are three main points to pay attention to:

1. Wire appearance

When purchasing wires, consumers should pay attention to the appearance of the wires should be smooth and flat, the insulation and sheath layer should not be damaged, the logo printing should be clear, and there should be no greasy feeling when touching the wires by hand. Viewed 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.

2. Conductor wire diameter

Consumers should pay attention to whether the conductor diameter is consistent with the cross-section indicated on the certificate when purchasing wires. If the conductor cross-section is too small, it is easy to cause the wire to heat up and cause a short circuit. It is recommended that household lighting circuit wires use products with specifications of 1.5 square millimeters and above; household appliances with high power such as air conditioners and microwave ovens should use wires with specifications of 2.5 square millimeters and above.

3. Standard use

The wiring should be standardized. It is best to use BV single-core wires to pass through the pipes for the fixed wiring. 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 the same route; the wires are connected to the electrical box (box) Don't touch the line when

The above is mainly to introduce the methods for general commercial and residential users to identify wires and cables. For mechanical and electrical engineering procurement personnel, this is generally the way to distinguish product quality.
