<p>PURPOSE:To do the installation and the maintenance of a power cable line easily and besides to make occupied area small by having a coupling part, which couples a gas passage pipe with a gas feed pipe, and a connection, which electrically connects a single-core polyethylene insulated cable with a three-core gas-filled power cable. CONSTITUTION:A three-core gas-filled power cable 11 is equipped with a three- core cable where three pierces of simple cores 30 are intertwined. Interposed jute 21 is filled up in the hollow region between the core of this three-core cable and a shielding layer 22. Furthermore, a gas feed pipe 19 and a gas passage spiral pipe 20 are set in the interposed jutes 21. The three-core gas-filled power cable 11 is connected to the polyethylene insulated cable, where three elements are twisted, by a connector 50 for communication and stop units 43. The two gas passage pipes 2 intertwined into the polyethylene insulated cable 1, where three simple cores are intertwined, are coupled to the gas feed pipe 19 of the three-core gas-filled power cable 11 through a connector 50 for communication.</p> |
