Welding Cable

Look at the label

The content of the cable such as rubber trailing cable for welding certificate produced by the regular manufacturer shall include:  3C certification mark, certification number, model specification, implementation standard, rated voltage, wire length, production date, manufacturer, inspector, factory name, factory address, fixed telephone, security mark, etc. The labels of counterfeit products are often not legible or complete.

Look at the surface

The plastic skin of the GB wire is soft and smooth, and the color is uniform. On its surface, it should also be printed with several items on the product certificate, such as: 3C certification mark, certification number, model, rated voltage, implementation standard, factory name, etc. At the same time, the writing must be legible and not easily erased.

Try bending

It is advisable to bend a wire head repeatedly by hand. Those with soft feel, good fatigue strength, large plastic or rubber feel elasticity and no cracking on the wire insulator are excellent products. The insulation layer of fake and inferior wire looks like it is very thick, but in fact most of it is made of recycled plastic. As long as it is pressed a little hard, the extrusion will become white, and the line will be broken if it is bent 4 to 6 times.

Tear the insulation

High quality insulation materials have a certain mechanical strength and flexibility, easy to tear not open. The inferior wire can be torn off or pinched off a piece by hand;

Look at the burn

According to the regulations, the insulation layer of the wire has a certain flame retardant. Strip off a section of insulation layer, light with a lighter, leave the open flame can continue to spontaneously combustion is inferior line.
