江蘇春晨電纜有限公司FDZYEYH風能電纜 風力發(fā)電機專用電纜(風力發(fā)電電纜),除滿足普通電纜的性能外,還必須滿足彎曲半徑小、頻繁扭轉的基本要求,由于風力發(fā)電電纜多用在氣候條件較為惡劣的地區(qū),一般多用在我國的北方地區(qū),氣候較寒冷,且晝夜溫差較大,因此風力發(fā)電電纜還必須滿足環(huán)境溫度-45℃~+50℃,運行溫度為-40℃~+50℃的使用條件。我公司自2005年初開始致力于風力發(fā)電機專用電纜技術的研究,參照德國DIN VDE的標準,對風力發(fā)電機專用電纜進行結構優(yōu)化設計,并選用世界上最優(yōu)的絕緣及護套材料,電纜的性能達到了國際領先水平。風力發(fā)電機專用電纜分為動力電纜、控制電纜電纜,電纜的優(yōu)點如下:
1、具有良好的耐低溫和耐磨性,以及耐疲勞性、耐氣候老化性能、耐微生物性能,對油品、化學品具有極好的耐腐蝕性。普通電纜不具有耐磨性和耐腐蝕性。FDZYEYH風能電纜
2、抗扭轉性能和彎曲性能優(yōu)異:成品電纜在-40℃的低溫環(huán)境下,能經(jīng)受正、反各四轉為一次、扭轉角度為 360°,次數(shù)不少于3000次的抗扭轉性能試驗,要求電纜試驗結束后導體不發(fā)生斷裂、護套表面不產(chǎn)生裂紋。普通電纜不適合在低溫情況下扭轉。
3、適用環(huán)境溫度-45℃~+110℃,運行溫度為-40℃~+110℃。普通電纜運行溫度為0℃~70℃。
4、電纜的敷設溫度不低于-30℃,普通電纜的敷設溫度為不低于0℃;FDZYEYH風能電纜
5、電纜彎曲半徑:固定安裝不小于電纜外徑的 4倍,移動安裝不小于電纜外徑的5倍。普通電纜的彎曲半徑為電纜外徑的 20倍。
sulated power cable, either chemical method or physical
method is employed to transform the molecular structure of PE from
chain into three-dimensional network,i.e. thermoplastic PE is transformed
into thermosetting XLPE. After cross-linking,the thermal and mechanical
properties of PE have been gratly improved while its excellent electrical
property are still retained.
The maximun permissible operating temperature of the conductor
of a XLPE insulated power cable is 90℃ which s higher than that
ofpaper,PVC or PE insulated power cable.The cable has the advantage
of simplicity in construction,lightness in weight,convenience in application
besides its xecellent electrical,thermal,mechanical and anti-chemical
corrosion properties.It can also be laid with no limitation of level defference
along the route.
