耐扭曲電纜的基本要求由于風(fēng)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(fēng)力發(fā)電電纜還必須滿足環(huán)境溫度
-45℃~+50℃,運(yùn)行溫度為-40℃~+50℃的使用條件。我公司自2005年初開始致力于風(fēng)力發(fā)電機(jī)
專用電纜技術(shù)的研究,參照德國DIN VDE的標(biāo)準(zhǔn),對風(fēng)力發(fā)電機(jī)專用電纜進(jìn)行結(jié)構(gòu)優(yōu)化設(shè)計(jì),
并選用世界上優(yōu)的絕緣及護(hù)套材料,電纜的性能達(dá)到了國際水平。風(fēng)力發(fā)電機(jī)專用電纜分為動力電纜、
控制電纜電纜,
電纜的優(yōu)點(diǎn)如下:[object Object]
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(xué)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。FDZ-YEYH風(fēng)能電纜 1, with good low temperature and wear resistance, as well as fatigue resistance,
weather resistance, antimicrobial properties, oil, chemicals with excellent corrosion
resistance. Ordinary cables do not wear and corrosion resistance. 2、抗扭轉(zhuǎn)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(zhuǎn)為一次、
扭轉(zhuǎn)角度為 360°,次數(shù)不少于3000次的抗扭轉(zhuǎn)性能試驗(yàn),要求電纜試驗(yàn)結(jié)束后導(dǎo)體不發(fā)生斷裂、
護(hù)套表面不產(chǎn)生裂紋。普通電纜不適合在低溫情況下扭轉(zhuǎn)。 2, the anti bending properties and excellent performance of torsion: finished cable at
low temperature of -40 DEG C, can withstand the positive and negative four to one,
torsion angle is 360 degrees, the number of not less than 3000 times the anti torsion
test, after the test re of cable conductor fracture does not occur, the sheath
surface no cracks. General cable is not suitable for torsion at low temperature. 3、適用環(huán)境溫度-45℃~+110℃,運(yùn)行溫度為-40℃~+110℃。普通電纜運(yùn)行溫度為0℃~70℃。 3, applicable environment temperature of -45 DEG C and C 110, operation temperature
is -40 DEG C 110. The operating temperature of the ordinary cable is 0 DEG C to 70
DEG C. 4、電纜的敷設(shè)溫度不低于-30℃,普通電纜的敷設(shè)溫度為不低于0℃; 4, cable laying temperature of not less than -30 DEG C, ordinary cable laying
temperature of not less than 0 degrees c; 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。 5, cable bending radius: fixed installation is not less than 4 times the diameter
of the cable, mobile installation is not less than the cable diameter of 5 times.
The bending radius of the ordinary cable is 20 times of the outside diameter of the cable.
