Abstract
The utility model discloses a polyurenthane insulating towing chain cable for wind electricity, comprising a modified polyurenthane protective layer, a tin plated copper wire braiding shielding layer, a lapping layer, a filling layer, a plurality of wire cores and polyurenthane insulating layers wrapped outside the wire cores, a plurality of the wire cores wrapped with the polyurenthane insulating layers are twisted into a cable core, the filling layer is wrapped among the twisted cable cores, and the lapping layer, the tin plated copper wire braiding shielding layer and the modified polyurenthane protective layer are sequentially wrapped outside the cable core. The middle of the twisted cable core is a main cable core, and the other wire cores are surrounded and distributed at the periphery of the main cable core; therefore, the cable adopts cable cores with soft material, the tin plated copper wire braiding shielding layer and the modified polyurenthane protective layer, so as to lead the cable to have good cold resistance, high-temperature resistance, ultraviolet radiation resistance and acid-base-salt corrosion resistance. The cable can be widely applied to electrical connection of a wind-electricity generator room and a storage battery below a tower pole, and the normal using environment temperature is -50 DEG C to +90 DEG C.
Description
Technical field
The utility model relates to the cable technology field, specifically relates to a kind of wind-powered electricity generation with the Polyurethane drag chain cable that insulate.
Background technology
At present, the cable that is applied to wind power generator is by core and is wrapped in the outer field restrictive coating of core and constitutes, the cable of this type is cold-resistant, high temperature resistant, UV resistant radiation and acid and alkali-resistance salt corrosion performance are all relatively poor, the normal serviceability temperature scope of such cable is-20 ℃～+ 70 ℃, when working temperature surpasses this value range, cause the cable aging speed to be accelerated, insulation or restrictive coating cracking, reduction of service life, cause electric loss rate to improve simultaneously, increase the cost consumption of product, increased cost for enterprise and user.Therefore how to make cable can improve these performances and become the problem that current cable technology industry is particularly paid close attention to.
The utility model content
The purpose of this utility model is to overcome the problems referred to above, and the wind-powered electricity generation that a kind of cold-resistant, high temperature resistant, UV resistant radiation and soda acid salt corrosion be provided is with the Polyurethane drag chain cable that insulate.
For reaching the purpose of foregoing invention, the technical scheme that is adopted is: a kind of wind-powered electricity generation is with the Polyurethane drag chain cable that insulate, comprise modified polyamine ester restrictive coating, tinned copper wire woven shield, lapping layer, packed layer, several core and be wrapped in the outer polyurethane insulating layer of every core, the described mutual stranded formation cable conductor of several cores that is enclosed with the polyurethane insulating layer, between the cable conductor after stranded packed layer is arranged, the cable conductor outside is enclosed with lapping layer, tinned copper wire woven shield and modified polyamine ester restrictive coating successively.The described stranded back cable conductor central authorities core of serving as theme, all the other cores are around being distributed in this master core periphery.
In sum, the utility model adopts core and the tinned copper wire woven shield and the modified polyurethane restrictive coating of special soft material, makes cable have good cold-resistant, high temperature resistant, UV resistant radiation, acid and alkali-resistance salt corrosion performance.The electrical equipment that is widely used in wind power generator cabin electric storage means to the tower bar connects; Normal environment for use temperature-50 ℃～+ 90 ℃.
