wdz Shaanxi power cables power cable wire and cable Certified

The interception of a dielectric layer, see its core is located in the middle insulating layer. Do not center the eccentric phenomenon as a result of the process is not high, if the power when using small'll leave it alone, once the electricity capacity, thinner side is likely to be current breakdown. 7. advisable first hand repeatedly bending a wire, all soft, good anti-fatigue strength, elastic plastic or rubber handle and wire insulator without cracking is the superior product. Wire outer plastic skin should be bright luster, fine texture, no open flame should be lit with a lighter. 8. First, as the volume of wire packing card, whether the Chinese national compulsory product certification "CCC" and production license number; to see whether the quality system certification; see certificate whether the norms; to see whether the name and address overhaul chapter, production date; see if printed with trademarks, specifications, and voltage on the wire. Depends on the wire cross section copper core, halogen wire and cable is mainly used for higher fire safety rating in place, so that when the wire connectors in construction do you have a solid electrical tape adhesive. Outside WDZYJV LSZH cable uses a halogen compound rubber. Characteristics of halogen compounds: the past 15 years (1987- present) flame retardant system gradually into Europe, and accepted a part of the cable manufacturing technology. While the United States is not the case, it is generally limited to products sold back to Europe before doing this provision. Europe and the United States are based on different national circumstances and background has a completely opposite view: that the spread of the concept of the United States: the root causes of the scourge that carbon monoxide (CO) gas generation and subsequent flashover ("flashover") during the CO is converted to CO2 The heat release. So, if some of the ways to control the process by heat release, you can reduce the fire hazard.
