WDZCYJV non-toxic environmentally friendly halogen wire and cable, wire and cable cat licensing

WDZCYJV copper halogen, non-toxic environmentally friendly wire and cable products for the rated voltage of the 1KV and petroleum, chemical, power plants, subways, hospitals, mines, airports and other high-rise buildings, etc. Here are fire retardant requirements for special occasions transmission and distribution lines, does not produce toxic gases and smoke in case of a fire burning. Products XLPE insulated power cable has excellent thermal - mechanical properties, excellent electrical properties and chemical resistance, but also has a simple structure, light weight, lay not drop restrictions, etc., are now widely used in urban power grids , mining and novel cable plant. Cable insulation - XLPE using chemical and physical methods polyethylene linear molecular structure into three-dimensional network structure of cross-linked polyethylene, thereby greatly improving the thermal mechanical properties of polyethylene, thereby maintaining excellent electrical performance. XLPE insulated power cable conductor maximum rated operating temperature of 90 ℃, than PVC insulation, polyethylene insulated cables are high, so the carrying capacity of the cable is also further improved. Product Standard GB / T12706.2-2008 rated voltage 1KV (Um = 1.2KV) to 35KV (Um = 1.2KV) extruded insulation power cables and accessories IEC60502-2: 2005 1 ~ 30KV rated voltage power cables with extruded insulation and accessory use features maximum rated operating temperature of the conductor operating temperature of 90 ℃ conductor short-circuit temperature must not exceed the maximum temperature of 250 ℃, the maximum time of no more than 5 seconds. Installation laying temperature cable installation laying temperature not lower than 0 ℃ to calculate air laying methods and benchmarks used in cable ampacity laying: ambient temperature 40 ℃ soil laying: Ambient temperature 25 ℃ WDZAYJV- conductor PVC insulated LSZH jacket, non-toxic environmentally friendly PVC insulated copper cable WDZRCBYJ- LSZH jacket, non-toxic and environmentally friendly WDZCNBYJ- conductor PVC insulated cable sheath halogen, non-toxic environmentally friendly PVC insulated copper cable WDZRCBV- LSZH jacket, non-toxic environmentally friendly cable WDZCNBV- low smoke PVC insulated copper Halogen-free, non-toxic and environmentally friendly WDZBYJV- conductor PVC insulated cable sheath halogen, non-toxic environmentally friendly PVC insulated copper cable WDZCYJV- LSZH jacket non-toxic environmentally friendly PVC insulated copper cable WDZCNYJV- LSZH jacket, non-toxic environmentally friendly PVC insulated copper cable WDZANYJV- LSZH jacket, no toxic environmentally friendly PVC insulated copper cable WDZBNYJV- LSZH jacket, non-toxic environmentally friendly PVC insulated copper cable WDZANBYJ- LSZH jacket, non-toxic environmental protection type cable PVC insulated copper WDZBNBYJ- halogen, non-toxic environmentally friendly cable cable cable installation suitable selection of cables rated cable U0 / U (Um) shown as: U0 is the cable design with the conductor of the rated power or frequency voltage between the metal shield, U is the rated power frequency voltage cable designed conductors, Um is the maximum value of the device can withstand the maximum system voltage. Depending on the environment and the load cable laying, is designed to select the cable specification model specifications. Non-armored for aerial, indoor, tunnels, ducts and other occasions, can not afford to unload external force, armored unarmoured with applicable conditions can be buried in the ground outside. Can withstand the mechanical force. Single-core cables laid in the pipeline are not allowed to produce the magnetic. Explosive, chemical corrosion and high temperature, low temperature and other occasions should choose special types of cables. Cable storage and transport cable in storage, should avoid prolonged outdoor packaging specifications sun exposure, a reliable seal both ends of the head, do not allow long-term storage in a humid environment, and the cable tray is not flat. Transport should consider fixed plate high and effective, does not allow several dishes simultaneously lifting when lifting, pushing down from above is strictly prohibited. Laying cabling should be installed using special tools, such as line planes, guide rollers, etc., to prevent mechanical damage during laying, away from heat. When the cable through pipe laying, pipe diameter is not less than 1.5 times the outer diameter tap more and more with the cable through the tube prohibit cable extrusion, the total area of ??the cable does not exceed 40% of the total area of ??the inner tube.
