6kV~35kV 交联聚乙烯绝缘电力电缆
XLPE Insulated Power Cable
交联聚乙烯绝缘电力电缆是采用化学方法或物理方法,使聚乙烯分子由线型分子结构转变为三维网状结
构,由热塑性的聚乙烯变成热固性的交联聚乙烯,从而提高了聚乙烯的耐老化性能、机械性能和耐环境能力，并
保持了优良的电气性能。
交联聚乙烯绝缘电力电缆导体的允许长期最高温为900C，较低绝缘电缆、聚氯乙烯绝缘电缆和聚乙烯绝
缘电缆高，且具有重量轻、结构简单、使用方便、耐化学腐蚀和敷设不受落差限制等优点。
近年来，公司先后按IEC标准为全国城网改造、首都国际机场、北京西客站、中央电视台、安顺电厂、泰
山核电站、二滩水电站、北仑电厂、伊敏电厂、扬州二电厂、上海地铁、宝钢集团、扬子石化等重点工程提供
该系列产品，质量优良，获得用户一致好评。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.
