Technical field
The utility model relates to a kind of power transmission cable, a kind of flexible cable that is used for offshore wind generating of saying so more specifically.
Background technology
Along with the world energy sources growth of requirement, the clean energy resource wind power generation also more and more comes into one's own, in wind generator system, cable is the vitals of power transfer, signal transmission and drag chain control, it is installed in the environment of awful weather with wind power plant, and the normal operation of whole wind power plant is played crucial effects.China's development wind power generation starts from the nineties in last century, but up to the present, China does not still have wind-force generating and special-purpose cable thereof, does not formulate corresponding national standards and industry standard temporarily yet, and all cable basic sources of using in wind power plant are in import.Because the environment in the place that wind power plant is installed and used is all abominable relatively, especially employed cable in the offshore wind power system, what not only need to possess is high temperature resistant and low temperature resistant, and the performance of flexible flame retardant, also need to possess the salinity corrosion that prevents in the seawater, anti-hydrolysis, and the performance of antibiotic acid-proof, because the circumstance complication of China is various, the coastline is longer, marine weather is complicated and changeable especially, therefore the temperature contrast of environment is bigger, for guaranteeing the operate as normal of wind generator facility, therefore be necessary the structure of existing wind electric power generation cable is made improvements, especially need be low temperature resistant at it, anticorrosion, with and weather-proof performance on the requirement that develops skill.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency, and a kind of a kind of flexible cable that is used for offshore wind generating that can better adapt to offshore wind power system is provided.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
The utility model is used for the flexible cable of offshore wind generating, comprise oversheath, at least one soft electric conductor and packed layer, soft electric conductor places the inside of oversheath, the inboard of oversheath also is provided with lapping layer, the outside of soft electric conductor also is provided with insulating barrier and screen, described screen comprises internal shield and outer shielding layer, and insulating barrier is between internal shield and outer shielding layer; Described oversheath inside also is provided with gnd conductor, further improves the safety in utilization of cable, and gnd conductor is coated by the ground line insulating layer; Packed layer outer shielding layer, between line insulating layer and the oversheath.
Further technical scheme is: described soft electric conductor has three, and the outside of every soft electric conductor all is provided with internal shield, insulating barrier and outer shielding layer.
Further technical scheme is: also be provided with braid between described outer shielding layer and the packed layer.
Further technical scheme is: described braid is to adopt tinned copper wire to be processed into.
Further technical scheme is: described outer shielding layer and internal shield are to adopt semi-conducting material to be processed into.
Further technical scheme is: described insulating barrier is to adopt rubber-plastic elastomer to be processed into.
Further technical scheme is: described packed layer is to adopt polypropylene rope.
Further technical scheme is: described soft electric conductor adopts tinned copper wire to tangle and forms.
Further technical scheme is: described oversheath is to adopt haloflex to be processed into.
Compared with prior art, the beneficial effects of the utility model are: the rubber-plastic elastomer that insulating barrier adopted can still keep good pliability under subzero 60 ℃ low temperature environment, anti-twisting property excellence under cryogenic conditions, the variations in temperature that can adapt to the field of employment preferably, the oversheath that cooperates haloflex to be processed into, can better prevent the corrosion that long period of soaking produces in seawater, gnd conductor has further increased cable fail safe in use simultaneously, packed layer can make cable profile rounding more, and it is of the present utility model simple in structure, be more suitable for wind power system use at sea, and its weatherability is strong, applied range.
