交聯聚乙烯絕緣電力電纜是采用化學方法或物理方法,使聚乙烯分子由線型分子結構轉變為三維網狀結構,由熱塑性的聚乙烯變成熱固性的交聯聚乙烯,從而提高了聚乙烯的耐老化性能、機械性能和耐環境能力，并保持了優良的電氣性能。 交聯聚乙烯絕緣電力電纜導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、結構簡單、使用方便、耐化學腐蝕和敷設不受落差限制等優點。 近年來，公司先后按IEC標準為全國城網改造、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品，質量優良，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. 產品標準Standard 本產品按GB12706《額定電壓35V及以下銅芯、濾芯塑料絕緣電纜》標準生產，同時還可根據用戶需要按國際電工委員會推薦標準IEC、英國標準、德國標準及美國標準生產。 The product is manufactured according to the standard of《GB12706 or IEC、BS、DIN and ICEA upon request. 適用范圍Applications 本產品適用于工頻額定電壓3.6/6kv～26/35kv輸配電線路作配送電能子用。 The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 3.6/6kv～26/35kv. 使用特性Operating characteristics · 工頻額定電壓U0/U為3.6/6kv～26/35kv。 Rated power-frepuency voltage U0/U: 3.6/6kv～26/35kv. · 電纜導體的最高允許工作溫度：90℃。 Max.admissible operating temperature of the conductor:90℃. · 短路時（最長時間不超過5s）電纜導體的最高溫度不超過2500C。 Max. short-circurt temperature of conductor shall not exceed 2500C.
