Abstract
The utility model discloses a low smoke and zero halogen high voltage power cable, including annular arrangement's power core tinned conductor, conductor shield, EP rubbers insulating layer, insulation screen, shielding band are restrainted around layer, polyester film around covering, fire -resistant non -woven fabrics around covering and thermoset low smoke and zero halogen flame retardant polyolefin elastomer sheath around covering, flexible tinned copper wire ground sinle silk in proper order from inside to outside. The cable of this kind of structure has strengthened the heavy burden stability of restrictive coating and resistant high -temperature flaming's stability, has improved cable sheathing layer environment application range greatly, and fine guard action is played with high voltage power cable to the connection to railroad locomotive, is adapted to very much the railway with harsh environment middle berth if use.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of low smoke and zero halogen high voltage power cable.
Background technology
The railway locomotive of current China develop rapidly period just, railway transportation greatly depends on the quality of passive infrastructure, and these infrastructure comprise: the cable of communication and power and wiring system.Modern bullet train has different requirements to the bandwidth of cable, safety, anti-electromagnetic interference capability and electromagnetic resistance etc.But what technology content was higher mostly depends on import, and cost is too high; Such as: for railway locomotive connection high voltage power cable.Therefore, we urgently change the state of the art of the long-term dependence on import of high technology content cable, develop a kind of high performance locomotive connection high voltage power cable, fill up the blank of China's cable industry, and greatly improve the security performance of rail vehicle cable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of low smoke and zero halogen high voltage power cable with good high-low temperature resistant, resistance to ozone and adverse circumstances performance requirement.
For solving the problems of the technologies described above, the technical solution of the utility model is: annular configuration power wire core tinned conductor, conductor shield, ethylene propylene rubber insulated layer, insulation screen, mask tape lapping layer, flexible tinned copper wire wire core bundle winding layer, polyester film lapping layer, fire-resistant nonwoven fabrics lapping layer and thermosetting low smoke halogen-free flame-retardant polyolefin elastomers sheath successively from inside to outside.
Further, described power wire core tinned conductor adopts the zinc-plated flexible conductor of the 5th class in GB/T3956-2008 standard, the bunchy lay ratio of cable conductor is (12 ~ 16) times, twisting lay ratio is again (8 ~ 14) times, the conductor shield that external sheath adopts three-layer co-extruded equipment to extrude, ethylene propylene rubber insulated layer and insulation screen.
The beneficial effects of the utility model are: solve the long-term dependence on import of existing low smoke and zero halogen high voltage power cable; and the problem that cost is too high; provide a kind of low smoke and zero halogen high voltage power cable; the cable of this structure enhances the heavy burden stability of restrictive coating and the stability of high temperature resistant flame; substantially improve the coat layer of power cable environment scope of application; railway locomotive connection high voltage power cable is played a very good protection, is adapted to very much railway and harsh environment laying use.
