Technical specifications for water-cooled cables for medium frequency furnaces The cross-section is in the range of 25 to 6000 square millimeters; the length is in the range of 0.3 to 70 meters, which conforms to the national standard GB.
1. The electrode (also called the cable head) is non-contact, no solder joint, no weld seam, and is processed with a whole copper rod on a CNC lathe and milling machine. It is beautiful and durable; the connection between the electrode and the wire is cold. Squeeze, do not hurt the line, the resistance is small.
Second, the outer casing, the use of hose, water pressure >0.8MPA, breakdown voltage is higher than 3000V. There is also a flame-retardant outer casing for users to choose in special occasions;
Third, the electrode and the outer casing are fastened. The cable below 500mm2 is made of copper clamp. The other ones are made of 1Cr18Ni9Ti. It is non-magnetic and does not rust. It is squeezed and fastened with large hydraulic equipment. It is beautiful, durable and has good sealing effect.
Fourth, the soft wire is processed by a fine enamel wire on a special winding machine. Soft, small bending radius, large effective section;
5. The enameled wire is used as a water-cooled cable, and the power transmission efficiency is high. Because of the insulation between each enameled wire, the intermediate frequency, high-frequency current is transmitted, and there is no surface skin effect. Compared with other water-cooled cables of the same cross-section, the heat is less when passing the same current;
6. Use the enameled wire to make the wire of the water-cooled cable, which can improve the service life of the water-cooled cable. Because the wire of the water-cooled cable is immersed in water for a long time, the working environment is very bad. In the past, we used copper bare wire as a water-cooled cable. When the water-cooled cable was used for a period of time, open the cable jacket and you will see a layer of green copper rust on the wire surface. Later, we switched to enameled wire to make water-cooled cable. Because the enameled wire has a protective layer of paint film, it can play a role in anti-corrosion. The user reports that the water-cooled cable made of enameled wire has a service life of 1.5 to 2 times that of bare copper wire.
