YJY XLPE insulated PE sheathed power cable, Tianjin cat Wire Factory

YJY XLPE insulated PE sheathed power cable laying indoors, tunnels and pipelines can also be buried in loose soil, but can not withstand tension and pressure. YJ represents Insulation XLPE (crosslinked polyethylene), XLPE i.e., by physical or chemical methods PE (Polyethylene) crosslinking, XLPE breakdown and can greatly improve its heat resistance, the advantage of maintaining the original PE. Finally, Y represents a sheath using PE (polyethylene). 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: 25 ℃ ambient temperature model name and model uses an aluminum core Copper Model Name Scope YJV YJY YJLV YJLY copper or aluminum conductor XLPE insulated PVC sheathed power cables Copper or XLPE insulated PVC sheathed power cable is suitable for indoor and outdoor laying, can withstand a certain degree of laying traction, but can not bear external mechanical forces occasions YJV22 YJV23 YJLV22 YJLV23 copper or aluminum conductor XLPE insulated steel tape armored PVC sheathed power cables Copper or XLPE insulated PVC sheathed Power cables for underground laying, able to withstand external mechanical forces, but can not withstand much pressure YJV32 YJV33 YJLV32 YJLV33 copper or aluminum conductor XLPE insulated, steel wire armored PVC sheathed power cables Copper or aluminum XLPE insulated, steel wire armored PVC sheathed power cable for high drop area, able to withstand external mechanical forces and considerable tension YJV42 YJV43 YJLV42 YJLV43 copper or aluminum conductor XLPE insulated thick steel wire armored PVC sheathed power cables Copper or XLPE insulated thick steel wire armored PVC sheathed power cable for high drop area, can bear external mechanical forces and considerable tension cable installation cable suitable selection of cables rated cable U0 / U (Um) shown as: U0 is the conductor of the cable designed or rated power frequency voltage between the metal shield, U is the rated power frequency voltage cable designed conductors, Um is the device can withstand the maximum system voltage maximum. 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. YJV cable specifications YJV cross-linked polyethylene insulation features and applications cables, such as the lack of electricity in the western region and the beautiful countryside of overhead cables are widely used from the underground low voltage AC cable (XLPE cable) development. PVC cable PVC cable plastic insulated power cable into the following low-voltage transformer connected to the low voltage cable equipment, XLPE three co-extruded high voltage power cables for underground rehabilitation and construction of rural power network is suitable for "rollout .
