Types and Characteristics of Water-cooled Cables
Water cooled cable for electric arc furnace: the electrode surface is tinned, corrosion resistant, with good conductivity. The end is provided with a lifting ring, convenient for site installation. The rubber tube and the electrode are fastened with two stainless steel clamps, safe and reliable. The outer protective sleeve is made of high-quality rubber tube, flexible, with good bending performance. The flexible conductor is made of high-strength enameled wire, corrosion resistant, without surface skin effect.
Water-cooled cable for submerged arc furnace: the electrode is processed with a whole copper bar; The flexible conductor is made of enameled wire, and there is no green rust in long-term use; The outer sheath rubber pipe is resistant to high working water pressure and will not break; The cooling water path is smooth and the cooling effect is good; The outer sheath rubber pipe has high puncture resistance voltage, large current transmission, safety and reliability; Various specifications and models for users.
Electroslag furnace water-cooled power cables: electrode has a variety of structures (flat flange type, bell mouth type, rotating electrode type), and the inlet and outlet positions have three types (on the electrode side; on the flange plane; on the electrode end face); The flexible conductor is made of enameled wire, and there is no green rust in long-term use; The outer sheath rubber pipe is resistant to high working water pressure and will not break; The cooling water path is smooth and the cooling effect is good; The outer sheath rubber pipe has high puncture resistance voltage, large current transmission, safety and reliability; Various specifications and models for users.
Submerged arc furnace water cooled cable: the electrode material is T2 red copper, the electrode structure can be made according to the user's requirements, and the surface is tinned; The position of water inlet and outlet can be determined according to the installation position of the user's equipment. The outer sheath rubber tube is subject to high temperature fire protection treatment, which is suitable for the working environment of submerged arc furnace and safe and reliable in transmitting large current.
Water-cooled cable of vacuum furnace: one end of the cable electrode is of the horn mouth lock nut type, connected with the induction ring in the vacuum furnace, and the other end of the electrode structure is of the flat flange type, connected with the capacitor. The outer sheath rubber tube of the cable has a taper seal ring, so as to ensure the sealing with the shell of the vacuum furnace. The water-cooled cable inside the vacuum furnace has a high-temperature protection treatment on the outer sheath. The cooling water of the water-cooled cable directly enters the induction ring in the vacuum furnace for circulating cooling. It is widely used in the vacuum sintering furnace of NdFeB magnetic materials, and can replace the imported cables.
Water-cooled cable of intermediate frequency furnace: soft conductor adopts enameled wire, when transmitting intermediate frequency current, it has no skin effect on the surface, high power transmission efficiency, low heat generation, and the outer sheath rubber tube is not easy to age; The enameled wire is softened, and the stress at the connection part with the electrode is small. When the furnace is tilted and inverted repeatedly, the connection part between the water-cooled cable electrode and the flexible conductor will not be broken.
