How To Choose Civil Wire And Cable?

With the development and popularization of household appliances, household electricity consumption has increased rapidly. In order to ensure the safety of household electricity consumption, consumers should pay attention to the following matters when purchasing and using wires:

1: Wire surface marking According to national standards, the surface of the wire should have continuous markings of the manufacturer's name, product model and rated voltage.

This is conducive to finding the manufacturer in time when a problem occurs during the use of the wire. Consumers must pay attention to this when purchasing wires. At the same time, consumers should pay attention to whether the manufacturer's name, product model, and rated voltage indicated on the certificate are consistent with the printed marks on the surface of the wire when purchasing wires, so as to prevent counterfeit products.

Two: the appearance of the wire

When purchasing wires, consumers should pay attention to the appearance of the wires should be smooth and smooth, the insulation and sheath layers are not damaged, the logo printing is clear, and there is no greasy feeling when hand-moulding the 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 should not be eccentric, and the insulation or sheath should have a certain thickness.

3. 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 the wires used in household lighting circuits should be 1.5 mm2 and above; household appliances with high power such as air conditioners and microwave ovens should use wires of 2.5 mm2 and above.

Fourth, the standardized use should be standardized wiring, the fixed line is best to use BV single-core wire 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 line; do not touch the wires when the wires are connected to the electrical box (box); in addition, household appliances that consume a lot of electricity such as air conditioners It should be powered by a separate wire; it is best to keep a certain distance between the wires used for weak current and strong current. Change the product structure, such as fire-resistant cables, etc.; improve process requirements, such as medical cables, etc.; combined products such as OPGW, etc.; facilitate installation and reduce equipment costs, such as prefabricated branch cables.
