6kV~35kV 交聯(lián)聚乙烯絕緣電力電纜
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900C，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。
近年來，公司先后按IEC標準為全國城網(wǎng)改造、首都國際機場、北京西客站、中央電視臺、安順電廠、泰
山核電站、二灘水電站、北侖電廠、伊敏電廠、揚州二電廠、上海地鐵、寶鋼集團、揚子石化等重點工程提供
該系列產(chǎn)品，質(zhì)量優(yōu)良，獲得用戶一致好評。CROSS-LINKED POLYETHYLENE(XLPE)INSULATED POWER CABLE
For XLPE insulated power cable, either chemical method or physical method is method is employed to
transform the molecular structure of PE from chain into three-dimensional network, i. e.
thermo-plastic PE is transformed into thermosetting XLPE. After cross-linking, the thermal and
mechanical properties of PE have been greatly improved while its excellent electrical property are
still retained.
The maximum permissible operating temperature of the conductor of a XLPE insulated power cable is
900C which is higher than that of paper, PVC or PE insulated power cable. The cable has the advantage
of simplicity in construction, lightness in weight, convenience in application besides its excellent
electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with
no limitation of level difference along the route.
According to the standards of IEC, in the last few years, We have supplied XLPE cables to the Chinese
urbon power network reconstruction project, Beijing Capital International Airport, Beijing West
Railway Station, CCTV Station, Anshun Power Plant, Qinshan Nuclear Power Station, Ertan Hydroelectric
Power Station , Beilun Power Plant, Yimin Power Plant, Yangzhou Second Power Plant, Shanghai Subway,
Bao Steel Group and Yangzi Petrochemical Company, etc.. The products were given highly evaluation
from customers.
