Abstract
The utility model discloses a temperature-resisting moisture-resisting oil-resisting marine flexible cable, which comprises conductors and a sheath layer outside the conductors. A plurality of thin copper wires with high conductive coating layers are stranded into bundles to form the conductors. The conductors are coated with the sheath layer. The sheath layer comprises an insulation layer, an isolation layer and an outer sheath layer, wherein the insulation layer which is made of polyolefin material is extruded outside the conductors; the isolation layer is extruded outside the insulation layer; and the outer sheath layer is extruded outside the isolation layer. The temperature-resisting moisture-resisting oil-resisting marine flexible cable has the advantages of simple structure, high temperature-resisting level, good oil-resisting performance, good aging-resisting performance, large carrying capacity, small bending radius, good moisture-resisting performance, good oil-resisting performance, flame resistance, environmental protection, long service life and the like.
Description
Technical field
The utility model relates to a kind of electric wire, specifically relates to the moisture resistance oil resistant flexible cable for warships of a kind of heatproof.
Background technology
At present, along with the develop rapidly of sea, river and transport by sea industry and defence engineering, various ships naval vessels and offshore oil platform etc. also constantly increase, and various kinds of equipment improves day by day to the specification requirement of cable.Traditional cable that is used for the system such as naval vessel, what generally all adopt is the cable of common crosslinked polyethylene, common ethylene propylene rubber insulated, polyolefin jacket and so on, the long-term working temperature of this class cable conductor is about 70 ℃; The minimum bending radius of cable is 6 times of outside diameters of cable when laying, and this type of current-carrying capacity of cable is little, and the cable cover(ing) oil resistance is relatively poor.If use the Other Engineering plastics, also can manufacture low-smoke non-halogen flame-retardant environment-friendly type shipboard cable, but used Engineering Material Price is high, market is difficult to accept.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model provides the moisture resistance oil resistant flexible cable for warships of a kind of heatproof, it is good that this cable not only has pliability, the characteristics that temperature resistant grade is high, and have the characteristics such as moisture resistance, oil resistant, fire-retardant, the feature of environmental protection, long service life, be fit to very much illuminator peculiar to vessel and household electricity circuit and use.
To achieve these goals, the technical solution adopted in the utility model is: a kind of heatproof is moisture resistance oil resistant flexible cable for warships, comprise the restrictive coating that conductor and conductor are outer, described conductor is to be made of many thin copper wire bundle strands with high conductivity coating, be wrapped with restrictive coating at conductor, restrictive coating is comprised of insulating barrier, separator and external sheath layer; Described insulating barrier is to extrude outside conductor take polyolefine material as material; Described separator extrudes outside insulating barrier; Described external sheath layer extrudes outside the separator.
Preferably, described separator is that compound copper-plastics band extrudes outside insulating barrier.
Preferably, described external sheath layer is that high flame resistance, low smoke halogen-free polyolefin material extrudes outside separator.
Its principle is: the utility model is by adopting high flame resistance, low smoke halogen-free polyolefin material, improved the temperature resistant grade of this type of cable, ampacity and the performance such as aging have also been improved simultaneously, and solved the not problem of oil resistant of common ship cable, employing has the thin copper wire bundle strand of high conductivity coating, has improved the stability of cable flexible conductor structure, thereby has further reduced the bending radius of cable, made things convenient for and used and construct, and used polyolefine material belongs to ep-type material.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, not only have temperature resistant grade height, oil resistance is good, ageing properties is good, ampacity is large, bending radius is little characteristics, and have the characteristics such as moisture resistance, oil resistant, fire-retardant, the feature of environmental protection, long service life; The utility model is convenient to batch production, and material source is wide, and price is low, and production cost is low, and material resistance is higher, and dielectric loss is less, is particularly suitable for illuminator peculiar to vessel and household electricity circuit and uses.
