Abstract

The utility model discloses a light-weight and thin-wall insulated communication cable used in ships and warships. A tinned copper conductor is arranged at the center of each insulated core of the cable, the outer layer of the conductor is provided with a fluorinated ethylene propylene first insulating layer and a foamed polyethylene second insulating layer successively to form the insulated core, two of the insulated cores are twisted into a paired core, a plurality of the paired cores are twisted into the cable core, a wrapping tape layer is wrapped around the outside of the cable core, and the outside of the wrapping tape layer is provided with a braided shielding layer and a sheath layer. The insulated communication cable of the utility model has advantages of light weight, small outer diameter, oil resistance, corrosion resistance, low temperature resistance, moistureproof performance and no halogenation, and can be used to satisfy the signal transmission requirements of new ships and warships.

Description

A kind of marine light thinwalled insulation telecommunication cable
Technical field:
The utility model relates to a kind of marine light thinwalled insulation telecommunication cable.
Background technology:
Develop rapidly along with China's shipping industry, the cable for ship market demand constantly enlarges, especially naval vessel telecommunication cable, be in great demand in the industry, and because the requirement of the whole stealth in naval vessel and carrying capacity, also require gradually lighter towards weight of all parts, the future development that external diameter is less, but in order to satisfy the requirement of telecommunication cable performance index, the naval vessel of cross-linking polyethylene materials is difficult to diminish with the telecommunication cable external diameter, entire outer diameter is difficult to compression, has been difficult to the requirement that satisfying the market is lightweight to cable, external diameter is little.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of marine light thinwalled insulation telecommunication cable, and it is lightweight, external diameter is little, oil resistant, corrosion-resistant, low temperature resistant, moistureproof, non-halogen, can satisfy the requirement of new type of ship signal transmission.
The utility model technical solution problem adopts following technical scheme:
A kind of marine light thinwalled insulation telecommunication cable, the center of cable insulation core is provided with tinned copper conductor, be provided with successively perfluoroethylene-propylene the first insulating barrier, polyethylene foamed the second insulating barrier formation insulated wire cores at described conductor skin, two described insulated wire cores are twisted into core, many described is twisted into cable core to core, is surrounded with belting layer outside described cable core, is provided with woven shield and restrictive coating outside described belting layer.
Described insulating barrier is combined by perfluoroethylene-propylene and polyethylene foamed.
Described restrictive coating is the low-smoke zero-halogen low-toxicity provided with flaming retardant cross-linked polyolefin sheath.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, external diameter is little, lightweight, cost is low: cable insulation is perfluoroethylene-propylene and polyethylene foamed combined insulation, because perfluoroethylene-propylene has higher disruptive field intensity, avoided the breakdown risk of simple use polyethylene foamed, the existence of the polyethylene foamed of the second insulating barrier, effectively reduce the dielectric constant of cable insulation, so that the cable insulation external diameter reaches the requirement of cable electrical property when can greatly reduce, with four-core nominal area of section 0.5mm 2Telecommunication cable is example, adopt combined insulation than adopting traditional cross-linked polyethylene insulated cable entire outer diameter to reduce 0.6mm, because external diameter reduces behind the cable twisting, braiding reduces simultaneously with the tinned wird copper consumption, and the sheath consumption also reduces accordingly, make whole cable weight reduce about 8kg/km cost about 4%.
2, the technique realizability is strong: because perfluoroethylene-propylene adopts pull-tube type to extrude, technical maturity has been avoided individual layer polyethylene foamed breakdown problem effectively, and polyethylene foamed is extruded in the perfluoroethylene-propylene insulating outer layer simultaneously, external diameter is stable, uniform in foaming, effectively guarantees the cable electrical property.
3, security reliability is high: because the perfluoroethylene-propylene anti-flammability is better than crosslinked polyethylene, when running into fire, can not burn, in the situation that relatively static, can guarantee the signal transmission of equipment, security performance improves greatly.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 conductor, 2 first insulating barriers, 3 second insulating barriers, 4 belting layers, 5 screens, 6 restrictive coatings.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1, the marine light thinwalled insulation telecommunication cable of the present embodiment, the center of cable insulation core is provided with tinned copper conductor 1, be provided with successively perfluoroethylene-propylene the first insulating barrier 2, polyethylene foamed the second insulating barrier 3 formation insulated wire cores at described conductor 1 skin, two described insulated wire cores are twisted into core, many described is twisted into cable core to core, be surrounded with belting layer 4 outside described cable core, be provided with woven shield 5 and restrictive coating 6 outside described belting layer 4, described restrictive coating 6 is the low-smoke zero-halogen low-toxicity provided with flaming retardant cross-linked polyolefin sheath.
The cable of the present embodiment makes by following technical process: the stranded multiply tin-coated copper of bunching machine twisted wire is as conductor 1, extrude perfluoroethylene-propylene the first insulating barrier 2 at conductor 1 external application high temperature extruder, outside the first insulating barrier, extrude polyethylene foamed the second insulating barrier 3, to behind the two eradication edge core pair twists many insulated wire cores is arranged in order be carried out stranding set and wrapped belting layer 4 on the cabler, at its external application braiding machine braiding tinned copper wire screen 5, extrude low-smoke zero-halogen low-toxicity provided with flaming retardant cross-linked polyolefin sheath layer 6 with extrusion equipment at last.
