Abstract
The utility model discloses a power cable for a chloroprene rubber sheath boat, which comprises two conductors respectively wrapped by first insulation layers, wherein, the two conductors are mutually twisted to form a strand with a twisted pitch ratio less than 14 times; a belting layer is arranged outside the strand; two tensile steel wires with fan-shaped sections are arranged between the belting layer and the first insulation layers; second insulation layers are respectively wrapped outside the tensile steel wires; a refractory layer of 01.-0.35mm in thickness is wrapped on the outer side of the belting layer; a sheathing layer is wrapped outside the refractory layer; the first insulation layers and the second insulation layers are made from ethylene propylene rubber; and the refractory layer adopts a multi-layer synthetic mica tape through overlapping and winding package. The power cable has excellent advantages of high flame retardancy, fire resistance, high insulation and the like, can transmit power in the environments with larger mechanical tension, ensures the safety of electric power transmission, and has great significance on reducing the property loss.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of neoprene rubber sheath ship power cable.
Background technology:
Shipboard cable easy breaking out of fire when overload operation and short circuit at present; High voltage cable for ship in the past causes cable to be prone to puncture easily; Make a big impact for the safety in production of offshore oil platform and the electric power transfer on various He Hai naval vessel; Therefore, the quality of shipboard cable more and more receives people's attention.Purpose is that cable can normally use a period of time when the breaking out of fire accident, thereby reduces casualties and property loss as far as possible.
The shipboard cable that uses at present; In order to reach fire-retardant; Generally all use halogen elements such as chloride, bromine; Its amount of being fuming very big with can enough become grievous injury to personnel, equipment, cable can't not use because of fire-resistant during breaking out of fire, to reality keep the safety in production and satisfy electric power transfer safety peculiar to vessel to greatest extent, the minimizing property loss is significant.
In addition, the mechanical strength of control cable peculiar to vessel and fire-resistance property often do not reach the demand of real work, influence the real work demand of cable.
The utility model content:
To the prior art problem, the purpose of the utility model provides a kind of neoprene rubber sheath ship power cable, is applicable to the ship power cable that bears electric energy transmitting under the environment of having relatively high expectations than great machinery pulling force, fire-resistance property.
The utility model technical scheme following:
Neoprene rubber sheath ship power cable comprises two conductors, and two conductors wrap up first insulating barrier outward respectively; It is characterized in that: the mutual stranded bunchy of two conductors that wraps up first insulating barrier; The twisting pitch ratio is less than 14 times, and the outside is enclosed with belting layer behind the bunchy, and being provided with two cross sections between belting layer and described first insulating barrier is fan-shaped tension steel wire; The tension steel wire is enclosed with second insulating barrier outward respectively; The described belting layer outside is enclosed with flame retardant coating, and flame retardant coating thickness is 0.1-0.35mm, and flame retardant coating is wrapped with restrictive coating.
Described neoprene rubber sheath ship power cable is characterized in that: it is ethylene-propylene rubber that described first insulating barrier, second insulating barrier adopt material.
Described neoprene rubber sheath ship power cable is characterized in that: described flame retardant coating adopts the overlapping wrapped formation of multilayer synthetic mica tape.
The utility model has the advantages that:
1. the utlity model has excellent properties such as high flame retardant, fire-resistant, high insulation, be applicable to and bear electric energy transmitting usefulness under the environment of having relatively high expectations, guaranteed that electric power transfer safety, minimizing property loss are significant than great machinery pulling force, fire-resistance property.
2. it is more reliable to the utlity model has Product Safety, to people and environmental nonpollution, can treat as general electric wire and lay and install, and installation is laid easy.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Neoprene rubber sheath ship power cable comprises 1, two conductor of two conductors, 1 outer first insulating barrier 2 that wraps up respectively; Wrap up two conductors, the 1 mutual stranded bunchy of first insulating barrier 2, the twisting pitch ratio is less than 14 times, and the outside is enclosed with belting layer 3 behind the bunchy; Being provided with two cross sections between the belting layer 3 and first insulating barrier 2 is fan-shaped tension steel wire 4, is enclosed with second insulating barrier 5 respectively outside the tension steel wire 4, and belting layer 3 outsides are enclosed with flame retardant coating 6; Flame retardant coating 6 thickness are 0.1-0.35mm; Flame retardant coating 6 is wrapped with restrictive coating 7, the first insulating barriers 2, second insulating barrier 5, and to adopt materials be ethylene-propylene rubber, and flame retardant coating 6 adopts the overlapping wrapped formation of multilayer synthetic mica tapes.
