185 sq power cable power cable cable factory in Shaanxi

WDZ-YJV halogen power cables using the domestic advanced production technology, new environmental protection materials GB weathering halogen plastic, technical indicators overall technical direction of flame retardant cable materials: 1) to improve high-tech products content (eg, phase interface compatibility technology, anti-aging technology, intumescent flame retardant technology, nanotechnology, special processing technology, etc.) 2) strict three low and two high requirements: low smoke, low toxicity, low corrosion, high flame and 3) improve (quality / price) is high limiting oxygen index LOI flame retardant wire and cable industry is the traditional evaluation of a flame retardant cable material, but not comprehensive technical parameters. To make up for its deficiencies, in recent years the industry has added another technical parameters --- LOI temperature index (TI, temperature index). The past 20 years TI parameters from scratch, from low to high. 1980s initially to 260 ° C, followed after a 280 ° C, 300 ° C, 330 ° C until 1998, 350 ° C. 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.
