Abstract
The utility model discloses an instrument cable for an offshore petroleum platform. The instrument cable comprises conductors, insulation layers, fireproof layers, an armor layer and a protection sleeve layer, wherein wire cores are formed by wrapping and winding two layers of alloy mica tapes around the tin-coated copper alloy conductors, each fireproof layer is formed by the two layers of alloy mica tapes, every three wire cores are combined and then insulation wire cores are formed by winding and wrapping an insulation layer around every three wire cores, six insulation wire cores are intertwisted, and a polyester tape wrapping tape layer and a plastic-aluminum composite belt separated shielding layer are wound and wrapped around the six insulation wire cores. The outer side of the separated shielding layer is provided with a second fireproof layer, an inner protection sleeve layer, the tin-coated copper wire woven armor layer and the protection sleeve layer, wherein the second fireproof layer consists of two layers of alloy mica tapes. Six anti-torsion and anti-pull nylon ropes are arranged among the six insulation wire cores. The instrument cable for the offshore petroleum platform can keep excellent insulation performance when being burnt at high temperature, and the instrument cable can continuously work in high temperature flames.
Description
technical field
The utility model relates to a kind of offshore oil platform instrument cable, belongs to technical field of electric wires and cables.
background technology
Along with scientific and technical development, to requiring also more and more higher with the cable of marine equipment.Conventionally flame retardant cable used is substantially all to adopt flame retardant insulation material, fire-retardant band, flame-retardant filler, flame-retardant sheath material.Its deficiency is: in the time of breaking out of fire, cable stops the performance of propagation of flame not strong, and flame easily spreads to insulating barrier.Boats and ships and personnel's safety is caused to very large hidden danger.The heaviness loss that fire brings to human society is serious.This just requires fire-resisting cable in flame combustion situation, still can keep maintaining operation in certain hour, so that circuit is unimpeded, and alarm, traffic light system guiding, evacuates the masses, and makes Fire lift, water pump and the fume extractor can continuous service in the state of accident.
utility model content
The utility model object is to provide a kind of offshore oil platform instrument cable, can in high-temp combustion situation, still can keep good insulation property, can operation continuously in thermal-flame.
Scheme of the present utility model is as follows: a kind of offshore oil platform instrument cable, comprise conductor, insulating barrier, fireprotection layer, armour and restrictive coating, the outer wrapped two-layer alloy mica tape composition fireprotection layer of described Tinplated copper alloy conductor forms core, after three core combinations, wrapped employing cross-linking radiation extrudes the insulating barrier formation insulated wire cores that polyolefin is made, the stranded rear wrapped polyester belt belting layer of six roots of sensation insulated wire cores and aluminium-plastic tape sub-shield; Armour, restrictive coating that outer the second fireprotection layer, inner restrictive coating, the tinned copper wire that two-layer alloy mica tape composition is also set respectively of described separated-shielding weaved; The antitorque nylon rope that draws of the six roots of sensation is also set between described six roots of sensation insulated wire cores.
Further, described inner restrictive coating and jacket layer all adopt the low cigarette polyolefin of irradiation crosslinking halogen-free to extrude moulding.
Further, the armour thickness of institute's art is 0.2-6mm.
The beneficial effects of the utility model:
The utility model uses thermoplastic halogen-free fire prevention polyolefin jacket material, can effectively prevent the burning of flame, improves fireproofing of cable performance.The utility model uses double-layer alloy mica tape, improves fireproofing of cable performance, extends cable useful life.After the utility model cable fire, mica is fully sintered on copper cash, forms a layer insulating, has certain mechanical strength and water-fast, can keep like this cable normal operation a few hours in the time of 1000 DEG C, can meet the requirement of fire-fighting and extreme severe rugged environment.
brief description of the drawings
Fig. 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 offshore oil platform instrument cable, comprise conductor, insulating barrier, fireprotection layer, armour and restrictive coating, the outer wrapped two-layer alloy mica tape 2 of described Tinplated copper alloy conductor 1 forms fireprotection layer and forms core, after the combination of three cores, wrapped employing cross-linking radiation extrudes the insulating barrier 3 that polyolefin makes and forms insulated wire cores, the stranded rear wrapped polyester belt belting layer 4 of six roots of sensation insulated wire cores and aluminium-plastic tape sub-shield 5; Armour 8, restrictive coating 9 that outer the second fireprotection layer 6, inner restrictive coating 7, the tinned copper wire that two-layer alloy mica tape composition is also set respectively of described separated-shielding 5 weaved; The antitorque nylon rope 10 that draws of the six roots of sensation is also set between described six roots of sensation insulated wire cores.
Described inner restrictive coating 7 and jacket layer 9 all adopt the low cigarette polyolefin of irradiation crosslinking halogen-free to extrude moulding.Described armour 8 thickness are 0.2-6mm.
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.
