Product Description
The following is an introduction to it:
- Main Features
- High Conductivity: It uses special materials and structural designs to reduce cable resistance, thereby enhancing power transmission efficiency.
- Excellent Cooling Performance: It is equipped with a water - cooling system that can effectively dissipate the heat generated by the current, preventing the cable from overheating and ensuring its normal operation in high - temperature environments.
- Good Corrosion and Oxidation Resistance: The metal parts of the cable are usually made of stainless steel or special alloys, and the outer sheath is made of high - temperature - resistant materials, which can maintain stable performance in harsh environments.
- Structural Design
- Conductor: Usually made of high - conductivity materials such as tinned copper stranded wire or enameled wire. The tinned copper stranded wire has good corrosion resistance, and the enameled wire can reduce the skin effect, improve the efficiency of current transmission, and is soft and flexible, with a small bending radius.
- Outer Sheath: It is made of a synthetic rubber tube with a reinforced cloth layer, which has the characteristics of high pressure resistance, high temperature resistance, and good bending performance.
- Electrode: The electrode is usually processed from a whole copper bar, and the surface is passivated or tinned to improve corrosion resistance and conductivity. The end of the electrode is often provided with a lifting ring for easy on - site installation, and the connection between the hose and the electrode is fastened by two stainless - steel clamps to ensure reliable sealing.
- Performance Requirements
- Electrical Performance: The breakdown voltage of the outer sheath rubber tube of the water - cooled cable is generally required to be not less than 2300V, and the maximum surface temperature rise (including the connection part) is not more than 40K.
- Mechanical Performance: For example, the test tension of a 200mm² nominal cross - sectional area is 15KN, and on this basis, the test tension value increases by 5KN for every 100mm² increase in the nominal cross - sectional area of the water - cooled cable.
- Sealing Performance: The outer sheath rubber tube should be able to withstand a working water pressure of not less than 0.6MPa, and there should be no leakage of cooling water at the interface with the electrode.
- Application Scenarios
- Steel and Non - Ferrous Metals Industry: It is widely used in arc furnace equipment in steel and non - ferrous metals smelting to transmit high - current electrical energy.
- Casting Industry: In the casting process, it is used in arc furnaces to provide power for metal melting.
- Other Industries: It can also be used in occasions requiring high - temperature, strong corrosion, or high - voltage environments, such as the electrolysis industry and chemical reactors.
