PVC wire and Copper conductor Wires

The main features of products: pure metal conductor, insulation and sheath, such as steel core aluminum stranded wire, copper bus, electric locomotive line; processing technology is the pressure processing, such as melting, rolling, drawing, stranding / pressing twist; products are mainly used in suburban and rural areas, users the main line, switch cabinet etc..

Power cable

The main features of the products are: crowded outside the conductor (around) insulation layer, such as overhead insulated cables, or a few cores (corresponding to the power system phase, the zero line and the ground), such as more than two core overhead insulated cables, or increases the jacket layer, such as plastic / rubber sheathed cable. The main technology has drawn, stranded, insulated out (wrapped), a cable, armored, protection layer extrusion, different process combination of various products have certain difference.

Electrical equipment with wire and cable

Communication cables and optical fiber (brief introduction)

Electromagnetic wire (winding wire)

Mainly used for all kinds of motor, instrument and meter, etc..


Selection The Best Lighting Cable


Check the appearance. Qualified products of its insulation (sheath) layer of soft, flexible and flexible electric cable, the surface layer is tight, smooth, no rough sense, and have a pure gloss.

The surface of the insulation pvc wires and cables(sheath) should be clear and resistant to wear. Non regular insulation material production, insulation layer feel transparent, brittle, no toughness.

Check the insulation layer. National standard for wire insulation layer uniformity of the most thin point, the average thickness of a clear data. The insulation layer of the normal electric wire is uniform, not the core, and is tightly packed in the conductor.

Check the certificate. Standard certificate of products should be marked with the name of the manufacturer, address, after sales service telephone, model, specifications and structure, the nominal section (that is, the usual 2.5 square, 4 square wire, etc.)
