Abstract
The utility model discloses a distortion-resisting highly-antiflaming medium voltage shield cable used in wind power generation. The shield cable comprises conductors, a semiconductive shielding layer, an insulating layer, an insulation shielding layer and a copper wire sparse-wound shielding layer, which are arranged from inside to the outside in turn. The shield cable also comprises an insulation shielding warping tape disposed between the insulation shielding layer and the copper wire sparse-wound shielding layer, and the copper wire sparse-wound shielding layer uniformly wraps the insulation shielding warping tape. With adoption of the structure where the insulation shielding warping tape is arranged outside the insulation shielding layer, invagination of the copper wire sparse-wound shielding layer is effectively prevented; and the copper wire sparse-wound shielding layer effectively adapts to the frequently twisting characteristics of wind power generation cables, and thus the shield cable provided by the utility model is superior in performance.
Description
Technical field
The utility model relates to a kind of warp resistance high flame retardant MV shielded cable used for wind power generation.
Background technology
Wind energy is a kind of clean regenerative resource, be also at present on the largest scale in numerous new forms of energy, technology is the most ripe, the power generation mode that has business development prospect most, can utilize nearly 1,000,000,000 kW of wind energy resources according to open source information demonstration China mainland and inshore, China's " planning of regenerative resource Long-and Medium-term Development " points out, the year two thousand twenty China wind-powered electricity generation total installation of generating capacity reaches 3,000 ten thousand kW, and 2013-2020 is still the gold period of being well worth doing.Wind electric power generation cable has control cables in wind-power engine room and tower cylinder, signal cable, warp resistance power cable etc., because of wind field environment severe, and power cable swings and distortion with impeller, so cable for wind power generation General Requirements is higher, as require low temperature resistant, oil resistant, warp resistance, weather, UV resistant, acid and alkali-resistance etc.Domestic wind electric power generation cable is substantially pressed the domestic industry standard such as TICW01 and is produced, and my company, because order needs, needs higher warp resistance and high flame retardant, requires environmental protection simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of warp resistance, high flame retardant, softness, has the wind field tower cylinder generating MV shielded cable of function of shielding, UV resistant.
Realizing this technical scheme that uses novel object is a kind of warp resistance high flame retardant MV shielded cable used for wind power generation, comprises from the inside to the outside: conductor, semiconductive shielding layer, insulating barrier, insulation screen, copper wire are dredged around screen; Also comprise and be arranged at insulation screen and the thin insulation shielding twining package tape between screen of copper wire; Described copper wire is dredged around screen uniform winding outside insulation shielding twining package tape.
On described conductor, cover tin coating.
Described insulation screen, insulation shielding twining package tape and copper wire are dredged and are jointly evenly extruded around three layers of screens, one-body molded.
Warp resistance high flame retardant MV shielded cable used for wind power generation also comprises that uniform winding is in the conductor twining package tape of conductor outside.
Described insulating barrier is EPR.
Warp resistance high flame retardant MV shielded cable used for wind power generation also comprises that being coated on copper wire dredges the sheath around the EVA of screen outside material.
Adopt technique scheme, the utlity model has following beneficial effect: the structure that (1) the utility model insulation shielding arranges insulation shielding twining package tape outward has effectively stoped copper wire to dredge caving in around shielding, copper wire is dredged the characteristic that has effectively adapted to the frequent distortion of wind electric power generation cable around shielding, therefore superior performance.
(2) the utility model can also arrange the sheath of EVA material, halogen-free environmental.
(3) the utility model meets UL1072 and relevant UL series standard, and after tested, product structure, performance all meet relevant criterion, flame retardant rating FT4.
