Description
Technical field
The utility model relates to a kind of power cable, is specifically related to a kind of offshore platform and uses cable.
Background technology
China is an ocean big country, has about 3,000,000 square kilometres of seas under its jurisdiction and 18000 kilometers coastlines, and the island of area more than 500 square metres has more than 5000, and marine resources are very abundant, and the exploitation of ocean concerns national security and rights and interests.Along with the variation of international situation and the growth of china's overall national strength, the importance and the urgency of development marine cause, construction ocean power highlight day by day, and ocean engineering science and technology has been put into national medium-to long-range program for scientific and technological development.
Offshore platform as the important terminal of ocean development, often is seated on the ocean farly apart from land, so transport some necessitys except cargo ship and helicopter, also needs the cable of a large amount of different purposes to support the family, activity in production.Power supply mainly is to lean on cable to accomplish on the ocean platform; But maritime environment is complicated and changeable, and the special operation environment of offshore platform can be described as life and operation under the ten minutes harsh conditions; This just requires used cable that performances such as excellent anti-mud, corrosion-resistant, salt spray resistance, oil resistant, cold-resistant, high flexibility, high flame retardant will be arranged; Particularly can be in low temperature environment anti-mud, anti tear, anticorrosive, keep flexibility, to guarantee the normal operation of offshore platform system.
The utility model content
The utility model has overcome the deficiency of prior art, provides a kind of offshore platform to use cable, solves prior art not enough problem aspect anti-mud, low temperature resistant, corrosion resistant, salt spray resistance, flexibility.
For solving above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of offshore platform is used cable; Comprise at least one copper conductor, rubber insulation and oversheath; This offshore platform also comprises semiconductive conductor shield, semiconductive insulation screen, filler, twining package tape, bed course and braiding armour with cable; Described semiconductive conductor shield is arranged between copper conductor and the rubber insulation, and described semiconductive insulation screen, filler, twining package tape, bed course and braiding armour are successively set between rubber insulation and the oversheath.
For making the utility model play better technique effect:
Technical scheme further is that above-mentioned copper conductor is stranded tin-coated copper conductor.
Technical scheme further is that above-mentioned filler is a polypropylene PP plastic ties, is applied to the filling of multicore cable, so that the cable rounding.
Technical scheme further is that above-mentioned twining package tape is the 0.1mm reinforced light non-woven fabrics, and this material light specific gravity is less than 65g/m
2, pulling force is strong, and is high temperature resistant, good insulating, and pliability is good.
Technical scheme further is above-mentioned bed course by density is that the Halogen mixture of 0.95～0.97g/cm3 constitutes; Have anti-mud, anticorrosion, anti-salt, performance such as weather-proof; Under-50 ℃ low temperature environment, still keep good pliability, the anti-twisting property of low temperature is excellent; Long-term work temperature maximum can reach 125 ℃; Tensile strength can reach more than the 15MPa; Elongation at break can reach more than 500%, and anti-salt bath performance is splendid, and belongs to recyclable material.
Technical scheme further is that above-mentioned braiding armour is a tinned copper wire braiding armour.
Technical scheme further is that above-mentioned oversheath is a halogen-free thermosetting mixture sheath.
Compared with prior art, the beneficial effect of the utility model is: the utility model can still keep good pliability under-50 ℃ low temperature environment, and the anti-twisting property of low temperature is excellent; Long-term work temperature maximum can reach 125 ℃; Tensile strength can reach more than the 15MPa; Elongation at break can reach more than 500%; Good waterproof performance; The anti-salt bath performance of specific rubber is splendid; Guaranteed that simultaneously electric field strength evenly distributes, had excellent shielding properties.Thereby the utility model has tangible technical advantage for the offshore platform under China's severe cold, heat, the coastal and island environment with the cable of anti-mud.
