Abstract

The invention discloses an ethylene propylene rubber insulation ship power cable. The cable is composed of conductor cable cores and three outer protection layers. The three outer protection layers are sequentially the zinc-plated copper wire braiding armor layer, the tinned copper belt armor polyethylene sheath layer and the LSOH polyolefin sheath layer from inside to outside. The conductor cable cores are silver-plated annealed aluminum alloy conductor cable cores, and two sets of conductor cable cores are extruded inside the zinc-plated copper wire braiding armor layer. Twelve sets of silver-plated annealed aluminum alloy conductor cable cores, two silver-plated annealed copper wire drainage wires, two sets of zinc-plated aluminum alloy metal hoses and a zinc-plated annealed copper wire drainage wire are extruded inside each silver-plated annealed aluminum alloy conductor cable core. The cable has the advantages of being resistant to dampness, heat and oil and flame retardant, and good in anti-interference capacity.

Description

A kind of ethylene propylene rubber insulated ship power cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of ethylene propylene rubber insulated ship power cable.

Background technology

Cable is a kind of conductive media, is widely used in petrochemical industry, the fields such as boats and ships.Cable is normally by the cable of several or the stranded similar rope of several groups of wires [often organizing at least two]; but the inner conductor of cable and external protection structure varied; according to different field need especially can be different; now; there is a kind of cable; transform, be suitable for various rivers seagoing vessel oceangoing ship electric energy transmitting.

Summary of the invention

In order to increase the practicality of prior art, the object of this invention is to provide the ethylene propylene rubber insulated ship power cable of a kind of moisture-proof, heat-resisting, oil resistant and fire-retardant feature.

The present invention takes following technical scheme to realize: a kind of ethylene propylene rubber insulated ship power cable, it is made up of conductor cable core and three layers of external protection, three layers of external protection are followed successively by zinc-plated proof copper-wire braided armour from inside to outside, tin-coated copper strip armouring pe sheath layer and low-smoke halogen-free polyolefin restrictive coating, conductor cable core is silver-plated annealed Al-alloy conductor cable core, arrange two groups, be extruded in zinc-plated proof copper-wire braided armour inner, described silver-plated annealed Al-alloy conductor cable core inside extrudes 12 groups of silver-plated annealed Al-alloy conductor thread cores, two silver-plated annealing copper wire drainage silks, two groups of zinc-aluminium-alloy metal hoses and a zinc-plated annealing copper wire drainage silk, outer wrapping one deck zinc-plated aluminium wire braiding armour of 12 groups of silver-plated annealed Al-alloy conductor thread cores of silver-plated annealed Al-alloy conductor cable core inside, one deck ethylene-propylene rubber ethene insulating barrier, one deck low smoke and zero halogen second propylene restrictive coating and one deck low smoke and zero halogen pe sheath layer, two silver-plated annealing copper wire drainage silks are evenly extruded between ethylene-propylene rubber ethene insulating barrier and low smoke and zero halogen second propylene restrictive coating, two groups of zinc-aluminium-alloy metal hoses are evenly extruded in ethylene-propylene rubber ethene insulating barrier, between low smoke and zero halogen second propylene restrictive coating and low smoke and zero halogen pe sheath layer, zinc-plated annealing copper wire drainage silk to be extruded on low smoke and zero halogen pe sheath layer and through low smoke and zero halogen pe sheath layer in outward.

Conductor outer wrapping in described silver-plated annealed Al-alloy conductor thread core one deck ethylene-propylene rubber polyethylene layer.

The present invention has following beneficial effect in sum: this kind of cable has moisture-proof, heat-resisting, oil resistant and fire-retardant feature, also has good interference free performance.

Accompanying drawing explanation

Fig. 1 is cross-sectional structure schematic diagram of the present invention.

Embodiment

As shown in Figure 1, a kind of ethylene propylene rubber insulated ship power cable, it is made up of conductor cable core and three layers of external protection, three layers of external protection are followed successively by zinc-plated proof copper-wire braided armour 2 from inside to outside, tin-coated copper strip armouring pe sheath layer 3 and low-smoke halogen-free polyolefin restrictive coating 4, conductor cable core is silver-plated annealed Al-alloy conductor cable core 1, arrange two groups, be extruded in zinc-plated proof copper-wire braided armour 2 inner, described silver-plated annealed Al-alloy conductor cable core 1 inside extrudes 12 groups of silver-plated annealed Al-alloy conductor thread cores 11, two silver-plated annealing copper wire drainage silks 16, two groups of zinc-aluminium-alloy metal hoses 17 and a zinc-plated annealing copper wire drainage silk 18, outer wrapping one deck zinc-plated aluminium wire braiding armour 12 of 12 groups of silver-plated annealed Al-alloy conductor thread cores 11 of silver-plated annealed Al-alloy conductor cable core 1 inside, one deck ethylene-propylene rubber ethene insulating barrier 13, one deck low smoke and zero halogen second propylene restrictive coating 14 and one deck low smoke and zero halogen pe sheath layer 15.

Embodiment: two silver-plated annealing copper wire drainage silks 16 are evenly extruded between ethylene-propylene rubber ethene insulating barrier 13 and low smoke and zero halogen second propylene restrictive coating 14, two groups of zinc-aluminium-alloy metal hoses 17 are evenly extruded between ethylene-propylene rubber ethene insulating barrier 13, low smoke and zero halogen second propylene restrictive coating 14 and low smoke and zero halogen pe sheath layer 15, and zinc-plated annealing copper wire drainage silk 18 is extruded on low smoke and zero halogen pe sheath layer 15 and also passes low smoke and zero halogen pe sheath layer 15 in outward.

Further, the conductor outer wrapping in described silver-plated annealed Al-alloy conductor thread core 11 one deck ethylene-propylene rubber polyethylene layer.

Outer wrapping one deck ethylene-propylene rubber ethene insulating barrier 13 of described zinc-plated aluminium wire braiding armour 12, outer wrapping one deck low smoke and zero halogen second propylene restrictive coating 14 of described ethylene-propylene rubber ethene insulating barrier 13, outer wrapping one deck low smoke and zero halogen pe sheath layer 15 of described low smoke and zero halogen second propylene restrictive coating 14.

The above is the embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
