Abstract

The invention discloses a waterproof type light multicore drainage cable. The waterproof type light multicore drainage cable is composed of control cable cores, grounding cable cores, silver plating annealed copper conductor cable cores, nickel conductor cable cores and six external protection layers. The six external protection layers sequentially comprise the poly tetra fluoro ethylene propylene insulating layer, the silver plating nickel strap armor layer, the silver plating copper strap shielding layer, the copper-plastic nickel strap composite membrane tape wrapping layer, the nickel strap armor polyethylene sheath layer and the chlorosulfonated polyethylene sheath layer from inside to outside. Nine sets of control cable cores are arranged, and twelve tinning nickel conductors are extruded inside each set of cable core. Four sets of grounding cable cores are arranged, and three tinning aluminum alloy conductors are extruded inside each set of cable core. Sixteen silver plating annealed copper conductor cable cores are arranged. Four sets of nickel conductor cable cores are arranged. The waterproof type light multicore drainage cable is resistant to high temperatures, high in gas tightness, good in water resistance, stable in electrical conductivity and good in drainage effect.

The invention belongs to field of cables, particularly relate to a kind of water proof type multicore drainage lightweight cable.

Background technology

At present, electric wire is widely used in every field, relate to people's lives, industrial production every field, so the consumption of cable is huge especially, also can be very high to the requirement of quality, but in every field, the quality purposes of cable is required it is different, as used electric wire in the computer equipments such as oil, chemical industry and aviation train, just require that cable has good resistance to elevated temperatures and good water resistance, drainage effect is good, could be durable in use, satisfy the demand.

Summary of the invention

In order to increase the practicality of prior art, the object of this invention is to provide a kind of high temperature resistant, air-tightness is strong, has good water resistance, the water proof type multicore drainage lightweight cable that drainage effect is good.

The present invention takes following technical scheme to realize: a kind of water proof type multicore drainage lightweight cable, it is by control conductor, ground connection core, silver-plated annealed copper conductor thread core, nickel conductor thread core and six layers of external protection composition, six layers of external protection are followed successively by polytetrafluoroethyl-ne propylene insulating barrier from inside to outside, silver-plated nickel strap armour, silver-plated copper strips screen, copper moulds nickel strap composite membrane belting layer, nickel strap armouring pe sheath layer and chlorosulfonated polyethylene sheath layer, described control conductor is set to nine groups, often organize core inside and be extruded with 12 zinc-plated nickel conductors, wherein one group is arranged on the center of cable, wherein four groups are extruded between polytetrafluoroethyl-ne propylene insulating barrier and silver-plated nickel strap armour, other four groups are evenly extruded in silver-plated nickel strap armour, silver-plated copper strips screen and copper are moulded between nickel strap composite membrane belting layer, described ground connection core is set to four groups, evenly be extruded in silver-plated nickel strap armour, silver-plated copper strips screen and copper are moulded between nickel strap composite membrane belting layer, be distributed in the gap between control conductor and control conductor, often organize core inside and be extruded with 3 zinc-plated aluminium alloy conductors, described silver-plated annealed copper conductor thread core is set to ten six roots of sensation, four tinned copper wire drainage threads are also extruded with between the polytetrafluoroethyl-ne propylene insulating barrier of cable inside and silver-plated nickel strap armour, described nickel conductor thread core is provided with four groups, often organize inside and extrude two nickel conductors.

Ten six roots of sensation silver-plated annealed copper conductor thread core is evenly distributed on the gap of silver-plated copper strips screen inside.

Four groups of nickel conductor thread cores are evenly extruded in polytetrafluoroethyl-ne propylene insulating barrier inside.

The present invention has following beneficial effect in sum: this kind of cable is high temperature resistant, and air-tightness is strong, has good water resistance, and electric conductivity is stablized, and drainage effect is good.
