Abstract

The utility model discloses a flexible mud-resisting medium-high voltage cable for ship and ocean engineering in the field of power cables, aiming at solving the problems that the cable can not resist high-low temperature, slurry or corrosion. The phase lines of the cable are twisted, the periphery of the flexible fine copper wire conductor is coated with a semiconductive conductor shielding layer, an ethylene propylene rubber insulating layer, a semiconductive insulation shielding layer and a metal split-phase shielding layer in sequence to form an insulated cable core. Three insulated cable cores are twisted to form a three-phase cable; and the clearances among the three insulated cable cores are filled with non-hygroscopic halogen-free flame retardant fillers; the periphery of the cable is lapped with a polyester tape inner lapping layer, the periphery of the polyester tape inner lapping layer is extruded with a halogen-free inner lining layer and then lapped with a polyester tape outer lapping layer, the outside of the outer lapping layer is provided with a metal armor layer, and the metal armor layer is extruded with a halogen-free mud-resisting polyolefin outer sheath. The flexible mud-resisting medium-high voltage cable can resist low-high temperature, mud and corrosion; and the flexible mud-resisting medium-high voltage cable has higher strength and can be used for development and utilization in the field of offshore energy.

Description

Technical field
The utility model relates to a kind of power cable, and particularly a kind of boats and ships and ocean engineering are with soft anti-mud medium and high voltage cable.
Background technology
Because the particularity of offshore engineering equipment operating environment and the use of high-power power-equipment, supporting with it medium and high voltage cable has been proposed more and more higher technical performance requirement, wherein most typical is requirement softness, low smoke, zero halogen, low temperature resistant, high temperature resistant, anti-mud, decay resistance, in addition, also need it to have higher-strength, the energy tension is difficult for wearing out etc.
On February 10th, 2010, publication number is the Chinese utility model patent of CN201402665, a kind of mesohigh fire-resisting cable is disclosed, aim to provide a kind of extraordinary mesohigh fire-resisting cable with good electric property and good fire-resistance property, the core of cable is coated with mica tape, band, flame-proof silicon rubber layer, vertical alclad alloy band and sheath outward successively; Between core and mica tape, flame-retardant filler is set.Though this cable has superiority aspect fire-resistant, can not satisfy boats and ships and ocean engineering low temperature resistant, high temperature resistant, the anti-mud of cable, corrosion resistant performance requirement.
The utility model content
For overcoming problems of the prior art, the utility model provides a kind of boats and ships and ocean engineering with soft anti-mud medium and high voltage cable, can low temperature resistant, high temperature resistant, anti-mud, corrosion-resistant, also have higher intensity.
For solving above technical problem, a kind of boats and ships provided by the utility model and ocean engineering are with soft anti-mud medium and high voltage cable, three thoroughly do away with the stranded back of edge core constitutes cable, three gaps of thoroughly doing away with the edge core are filled with non-hygroscopic halogen-free flameproof inserts, the periphery of described cable is surrounded with lapping layer in the polyester belt, lapping layer is extruded with the Halogen inner covering outward in the described polyester belt, described Halogen inner covering is surrounded with the outer lapping layer of polyester belt outward, the outer lapping layer of described polyester belt is provided with the metal armouring layer outward, and described metal armouring layer is extruded with the Halogen polyolefin of anti-mud oversheath outward.
With respect to prior art, the utility model has been obtained following beneficial effect: non-hygroscopic halogen-free flameproof inserts has fire retardation, and compliance with environmental protection requirements; The setting of the outer lapping layer of lapping layer and polyester belt makes cable when bending in the polyester belt, layer with layer between can slide relative, avoid producing bigger internal stress; The Halogen inner covering makes cable have good fire retardation; The Halogen polyolefin of anti-mud oversheath has good physical and chemical performance, makes cable not only have elasticity, simultaneously also have the effect of oil resistant, salt tolerant, anti-mud, and cable is aging slow, long service life; The metal armouring layer has the effect that strengthens the cable resistance to tension, also makes it can bear certain mechanical pressure, also has good shielding action simultaneously; Above structure makes that cable has that soft bending radius is little, high strength, corrosion-resistant, shield, the advantage of high temperature resistant and low temperature.
As preferred version of the present utility model, described insulated wire cores comprises the stranded soft thin copper wire conductor of phase line, the periphery of the stranded soft thin copper wire conductor of described phase line is coated with the semiconductive conductor shield, described semiconductive conductor shield is coated with ethylene propylene rubber insulated layer, described ethylene propylene rubber insulated layer is coated with the semiconductive insulation screen, and described semiconductive insulation screen is coated with metal phase-splitting screen.Ethylene propylene rubber insulated layer is wrapped in outside the semiconductive conductor shield by extruding, ethylene-propylene rubber has good insulation performance effect and heat resistance, the semiconductive conductor shield can be eliminated the rough of the stranded soft thin copper wire conductive surface of phase line, avoids Electric Field Indensity on Surface of Conductor to increase; The semiconductive insulation screen makes ethylene propylene rubber insulated layer form good the contact with metal phase-splitting screen, prevents to produce in the cable running free discharge.
As preferred version of the present utility model, described metal armouring layer adopts tinned copper wire braiding armour.
As preferred version of the present utility model, described metal armouring layer adopts zinc-plated copper wire braiding armour.
