Abstract

The utility model discloses an ocean engineering electric cable comprising conductors, insulating layers and a protection sleeve layer. The outer sides of the tin-coated copper conductors are wrapped with the insulating layers made of flame retarding and oil resistant silicone rubbers, and therefore conductor cores are formed; every three conductor cores are combined and then are wrapped with a wrapping belt layer made of a polyurethane; an insulating wire core is formed by weaving a tin plated steel wire shielding layer outside each wrapping belt layer; five insulating wire cores are intertwisted, and then a wrapping belt layer II made of a polyurethane is wound and wrapped around the five insulating wire cores; a tin plated steel wire shielding layer II is woven outside the wrapping belt layer II, the outer side of the shielding layer II is wrapped with an greasy filth resistant chloroprene rubber inner lining layer which is high in flame retarding performance, and the outer side of the inner lining layer is wrapped with an armor layer and the protection sleeve layer; insulating wire cores II in which the conductors are wrapped with the insulating layers are arranged among the insulating wire cores, and the center of the electric cable is provided with a nylon ropte. The ocean engineering electric cable conforms with performance indexes such as low smoke, halogen free property, flame retardation and the like of a conventional ocean engineering electric cable; the ocean engineering electric cable is also characterized by oil resistant property, mud resistant property, wear resistant property and the like.

Description

A kind of cable for ocean engineering

technical field

The utility model relates to cable industry, is specifically related to a kind of cable for ocean engineering.

background technology

Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and be often twisted into round Yi Gen center, whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.

Because the every technical property requirements of petroleum platform cable is very high, domestic development is started late.For realizing the production domesticization of oil drilling facility-specific cable, domestic have cable factory to succeed in developing 2000V and following offshore oil and warship ship power cable with reference to military standard GJB1916-94 " naval vessel low smoke cables and flexible cord general specification ", Norway electrical standard NEK606-2009 " Halogen for offshore platform/anti-mud cable ", the standard IEEE 45-1998 of AAEE " the boats and ships electrical installation code that IEEE recommends " and the requirement of the U.S. DAA-1048B of SURPENANT company technical specification, tentatively realized oil platform and ship cable production domesticization.

utility model content

The purpose of this utility model is to provide a kind of cable for ocean engineering, meets ocean engineering cable and has low cigarette, Halogen, the performance index such as fire-retardant, solves oil resistant, resistance to mud, the problem such as wear-resisting simultaneously.

Scheme of the present utility model is as follows: a kind of cable for ocean engineering, comprise conductor, insulating barrier, restrictive coating, described tinned copper conductor outside is enclosed with respectively and adopts the insulating barrier formation that Flame-Retardant and Oil-Resistant silicon rubber is made to lead core, lead the belting layer that the rear parcel of core combination polyurethane is made for three, described belting layer weaves insulated wire cores after tin plated steel wire screen outward, five belting layer II that the stranded rear wrapped polyurethane of insulated wire cores is made, described belting layer II weaves tin plated steel wire screen II outward, described screen II outside is enclosed with high flame retardant oil resistant mud neoprene inner covering, described inner covering is wrapped with armour and restrictive coating, the insulated wire cores II that conductor wrap insulate layer is also set between described insulated wire cores, cable center arranges nylon rope.

Further, described armour adopts zinc-coated wire armouring to form.

Further, described oversheath adopts high flame retardant oil resistant mud neoprene.

Further, described conductor cross sectional area is 0.5-100mm ².

The utlity model has high flexibility, high-wearing feature, and there is good electric property; Cable center arranges nylon rope, anti-dilatory; Cable insulation adopts silastic material, and the halogen gas of overflowing when burning, gas aqueous ph value and conductivity are low, have low-corrosiveness energy; When cable fire, generate smog few, and possess the performances such as wear-resisting, anti-tear, oil resistant, resistance to ozone, oil resistant mud, high flame retardant, cable overall dimension is little can farthest reduce the space of saving oil pipeline.

brief description of the drawingsfig. 1 is structural representation of the present utility model.

embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

A kind of cable for ocean engineering, comprise conductor 1, insulating barrier, restrictive coating, described tinned copper conductor 1 outside is enclosed with respectively and adopts insulating barrier 2 formations that Flame-Retardant and Oil-Resistant silicon rubber is made to lead core, lead the belting layer 3 that the rear parcel of core combination polyurethane is made for three, the described outer braiding tin plated steel wire of belting layer 3 screen 4 rear insulated wire cores, five belting layer II 5 that the stranded rear wrapped polyurethane of insulated wire cores is made, the described outer braiding tin plated steel wire of belting layer II 5 screen II 6, described screen II 6 outsides are enclosed with high flame retardant oil resistant mud neoprene inner covering 7, described inner covering 7 is wrapped with armour 8 and restrictive coating 9, the insulated wire cores II 10 that conductor wrap insulate layer is also set between described insulated wire cores, cable center arranges nylon rope 11.

Described armour adopts zinc-coated wire armouring to form, and described oversheath adopts high flame retardant oil resistant mud neoprene, and described conductor cross sectional area is 0.5-100mm ².

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
