珠江高压电(dian)缆YJV22
珠江电缆中高压电缆
怎么差异高压电缆和低压电缆
首要能够(gou)看结构。高压电缆层(ceng)数多，剥开最外(wai)层(ceng)里边还有(you)铠装、屏蔽层(ceng)、绝(jue)缘(yuan)层(ceng)、导体(ti)等。低压电缆一(yi)般(ban)拨开最外(wai)层(ceng)，里边便是绝(jue)缘(yuan)层(ceng)或许导线。
其次，高压(ya)电缆(lan)绝缘层比较厚，低压(ya)电缆(lan)绝缘层比较薄(bo)。低压(ya)电缆(lan)绝缘层一(yi)般在3毫米(mi)以内(nei)，高压(ya)电缆(lan)绝缘层一(yi)般在5毫米(mi)以上。
再次(ci)，能够看电(dian)缆(lan)最(zui)(zui)外层(ceng)的(de)铭(ming)牌。在电(dian)缆(lan)的(de)最(zui)(zui)外层(ceng)上一般(ban)都印刷了电(dian)缆(lan)的(de)相关参数(shu)(shu)，其中就包含电(dian)缆(lan)类型(xing)、截(jie)面积、额外电(dian)压、长度等参数(shu)(shu)
高(gao)压(ya)电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)是电(dian)(dian)(dian)(dian)(dian)压(ya)等(deng)级(ji)在1kV伏以(yi)上至750KV总(zong)称(cheng)高(gao)压(ya)电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)。首要用(yong)处是电(dian)(dian)(dian)(dian)(dian)力(li)(li)部门(men)(men)用(yong)于运(yun)送电(dian)(dian)(dian)(dian)(dian)力(li)(li)，电(dian)(dian)(dian)(dian)(dian)压(ya)改换之用(yong)。一般常用(yong)于远距(ju)离运(yun)送电(dian)(dian)(dian)(dian)(dian)力(li)(li)，变电(dian)(dian)(dian)(dian)(dian)站电(dian)(dian)(dian)(dian)(dian)压(ya)等(deng)级(ji)改换。咱(zan)们常见常用(yong)的(de)电(dian)(dian)(dian)(dian)(dian)压(ya)等(deng)级(ji)都在220KV以(yi)下。远距(ju)离运(yun)送电(dian)(dian)(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)(dian)(dian)压(ya)等(deng)级(ji)都是超高(gao)压(ya)。都是电(dian)(dian)(dian)(dian)(dian)力(li)(li)部门(men)(men)指定专门(men)(men)电(dian)(dian)(dian)(dian)(dian)力(li)(li)工人施工、专门(men)(men)保护(hu)。对这方面的(de)高(gao)压(ya)电(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)许多(duo)人都不太(tai)清(qing)楚的(de)。
高(gao)压电(dian)缆(lan)依据耐(nai)压等级有(you)多种(zhong)类型分(fen)为(wei)：1。油浸纸绝(jue)(jue)缘(yuan)电(dian)缆(lan)。耐(nai)压等级有(you)1KV～750KV。2。塑料绝(jue)(jue)缘(yuan)电(dian)缆(lan)。耐(nai)压等级1KV～220KV。3。橡(xiang)皮绝(jue)(jue)缘(yuan)电(dian)缆(lan)。耐(nai)压等级1KV～138KV。4。气体绝(jue)(jue)缘(yuan)电(dian)缆(lan)。耐(nai)压等级220KV～500KV。
低压(ya)绝(jue)缘(yuan)(yuan)电(dian)缆适(shi)用(yong)(yong)(yong)于(yu)耐压(ya)450V/750V以下的电(dian)气配备用(yong)(yong)(yong)处极广分类也许多(duo)。一般工业用(yong)(yong)(yong)塑料(liao)绝(jue)缘(yuan)(yuan)电(dian)缆用(yong)(yong)(yong)于(yu)固定敷设。移动用(yong)(yong)(yong)橡套低压(ya)绝(jue)缘(yuan)(yuan)电(dian)缆。建筑装(zhuang)置首(shou)要(yao)用(yong)(yong)(yong)于(yu)电(dian)源总(zong)电(dian)路、各(ge)干支、分支路的敷设。也有用(yong)(yong)(yong)于(yu)电(dian)梯(ti)装(zhuang)置的特(te)种扁形(xing)电(dian)梯(ti)电(dian)缆。
