中低壓銅芯及鋁芯交聯(lián)聚乙烯絕緣電力電纜(YJV電纜,YJV22電纜,YJLV電纜,YJLV22電纜)
XLPE Insulated Power Cable |
交聯(lián)聚乙烯絕緣電力電纜是采用化學(xué)方法或物理方法,使聚乙烯分子由線型分子結(jié)構(gòu)轉(zhuǎn)變?yōu)槿S網(wǎng)狀結(jié)構(gòu),由熱塑性的聚乙烯變成熱固性的交聯(lián)聚乙烯,從而提高了聚乙烯的耐老化性能、機(jī)械性能和耐環(huán)境能力,并保持了優(yōu)良的電氣性能。
交聯(lián)聚乙烯絕緣電力電纜導(dǎo)體的允許長期最高溫為90攝氏度,較低絕緣電纜、聚氯乙烯絕緣電纜和聚乙烯絕緣電纜高,且具有重量輕、結(jié)構(gòu)簡單、使用方便、耐化學(xué)腐蝕和敷設(shè)不受落差限制等優(yōu)點(diǎn)。

U0-電纜設(shè)計(jì)用的導(dǎo)體對(duì)地或金屬屏蔽之間的額定工頻電壓;
U-電纜設(shè)計(jì)用的導(dǎo)體間的額定工頻電壓;
Um-設(shè)備可承受的“最高系統(tǒng)電壓”的最大值。
The rated voltage of the cable for a given
applixation shall be suitable for the
operating conditions
in the system in which the cable is used,and
is expressed in the form of U0/U(Um)kv
Where:
U0-The rated power-frequency voltage between
conductors and earth metallic screen ,for
which the cable designed;
U - The rated power-frequency voltage
between conductos, for which the cable
designed;
Um- The maximum value of the“highest system
voltage”for which the equipment may beused.
