Technical specification of water-cooled cable for metal smelting furnace
Technical specifications of water-cooled cables for metal smelting furnaces The cross-section is in the range of 25-6000 square millimeters; the length is in the range of 0.3-70 meters, and it conforms to the national standard GB. To
1. The electrode (also called the cable head) is non-contact, no solder joints, and no welds. It is processed by a whole copper rod on a CNC lathe or milling machine. It is beautiful and durable; the electrode and the wire are connected by cold Squeezing, does not damage the line, and has low resistance. To
2. Outer tube, use rubber tube, water pressure resistance>0.8MPA, breakdown voltage resistance higher than 3000V. There is also a flame-retardant outer tube for users to choose in special occasions;
3. Fasten the electrode and the outer tube. For cables below 500mm2, use copper clamps. Others use 1Cr18Ni9Ti materials, which are non-magnetic and rust-free; they are squeezed and tightened by large hydraulic equipment, which is beautiful, durable, and has a good sealing effect;
4. The soft wire is processed on a special winding machine with fine enameled wire. Soft, small bending radius, large effective cross section;
5. Using enameled wire as water-cooled cable, the power transmission efficiency is high. Because of the insulation between each enameled wire, it conducts medium-frequency and high-frequency currents, and has no surface skin effect. Compared with other water-cooled cables of the same cross-section, it generates less heat when passing the same current;
6. Using enameled wire as the conductor of the water-cooled cable can increase the service life of the water-cooled cable. Because the wires of the water-cooled cable are immersed in water for a long time, the working environment is very harsh. In the past, we used bare copper wires to make water-cooled cables. When the water-cooled cables were used for a period of time, when the cable jacket was opened, a layer of green copper rust would be seen on the surface of the wires. Later, we switched to enameled wire as water-cooled cable. Because the enameled wire has a paint film protective layer, it can play a role in anti-corrosion. Users report that the service life of water-cooled cables made of enameled wires is 1.5 to 2 times that of bare copper ires.
