SDL series of Water Cooled Cable 1.1 Characteristic 1) Strands of copper twist wire are wound together by special process to avoid all kinds of drawbacks caused by bore welding. Special insulating materials are used against strands rubbing and electric erosion, therefore the service life of cable is extended by eight to ten years. The well-distributed current is favourable to three phases equilibrium, for this reason, the hot spots are smoothed. 2) The cable joint is made into plane joint using the electrolytic copper bar to ensure better pressure joining, reliability and conductibility. Moreover, because the flow rate and direction of cooling water at the joint of the cable are very reasonable, to be able to make every strands of cable to be cooled sufficiently. 3) All parts of cable are made of nonmagnetic material. 4) Special heat-resistance rubber is adopted for making outer layer of cable and a few of bumper protection sleeves are used to avoid the rubbing among the rub pipes during operation. 5) Since the electrolytic copper twist wires are pressed to the copper joint, the contact resistance is nearly zero. 6) The water pressure testing on the cable is done before delivering, ensuring non- leakage of cooling water. 7) All strands wires are supported by the core pipe, ensuring the cable position not changed the operation. 8) Because of lower reactance of cable and steady operation, it is able to increase the output of transformer by 10-15 percent, with a distinguished electricity saving.

The outside dimension and the connect dimension can be made as per users special requirement. The joint and the soft copper conduit are pressed together tightly with little contact electric resistance. 2) The soft copper conduit is made of copper bare wire with a cylindrical net structure, the current is distributed equally on the cable which can lower reactance. 3) The outer layer pipe of the cable is made of heat resistance wear resistance, voltage resisting rubber. Bumper protection sleeves can be offered at users option, the sleeves are used to avoid the rubbing among the rubber pipes during operation, thus the service life of the cable is extended. 4) The connection of the copper joint and the rubber pipe is strengthened by hoops which are pressed by special equipment, this connection structure can bear 0.6Mpa hydraulic pressure.
