中文摘要:
      市区内的公用事业单位,拥有不少管道式及直埋式地下电缆。由于XLPE绝缘电缆的兴起,需要将XLPE电缆与管道式及直埋式电缆相连接。不同绝缘的电缆转换接头,就是通过人为的技术,将XLPE电缆与混合式的电缆形成一体化的电缆系统。本文叙述转换接头成功地开发、设计、试验及安装,达到了新的技术要求。这些转换接头系将一条管道内置三根138kV高压充油(液体)(high pressure fluid filled HPFF)电缆,与电缆沟内分离敷设的三根XLPE电缆相连接。这种转换接头采用prymian的插入式装配(Cliek-fit)高压连接系统,因此不需要将XLPE电缆安装在管道内。
英文摘要:
      Many utilities have a substantial namber of existing underground pipe type and self contained cables.The growing use of XLPE insulated cables creats a need to connect XLPE cables to pipe type and self contained cables. Transition joints connecting cables with different insulating technologies can be instrumental in the integration of XLPE cables into systems with mixed cables technologies.This article describes the succesful development,design,testing,and installation of a transition joint with new capabilities.These transition joints connect one steel pipe containing three 138kV high pressure fluid filled (HPFF) cable with three XLPE cables installed separately in ducts. These transition joints utilize Prysmian’s Click-Fit® High Voltage Jointing System and eliminate the need to install the XLPE cables in steel pipe.
