Three Phase Water Cooled Cable Heat Resistance Electric arc furnace

S Water Cooled Power Cable Special heat-resistance rubber nonmagnetic material

SDL series of Water Cooled Cable

1.1 Characteristic

1. 1Strands 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.

1. 2The 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.

1. 3All parts of cable are made of nonmagnetic material.

1. 4Special 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.

1. 5Since the electrolytic copper twist wires are pressed to the copper joint, the contact resistance is nearly zero.

1. 6The water pressure testing on the cable is done before delivering, ensuring non- leakage of cooling water.

1. 7All strands wires are supported by the core pipe, ensuring the cable position not changed the operation.

1. 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.
2. With this kind of cable, the current density can be raised, consequently the copper is saved, and the breaking off of copper wires and the spreading out of strands are prevented.

This new type of cable is easy to install, is reliably operated and is convenient for maintenance, are welcomed by maintenance workers.
