Water cooled cable, commonly known as water cable, is a special type of hollow water cable used for high current heating equipment. It mainly consists of three parts: electrode (cable head), soft wire, and outer protective sleeve.
Structural characteristics:
Electrode: Whole copper rod processing, surface passivation or tin plating to improve conductivity and corrosion resistance.
Soft wire: woven with tinned copper stranded wire or enameled wire, high flexibility, large cross-sectional area, capable of carrying high current.
Outer protective sleeve: Reinforced with a layer of synthetic rubber, it has high pressure resistance and can withstand working water pressure ≥ 0.6 MPa, preventing leakage.
Cooling channel: The hollow structure allows cooling water to circulate inside the pipe, quickly removing the heat generated by the wires and maintaining a cable temperature rise of ≤ 40 ° K.
Main application scenarios:
High current power supply for various industrial electric furnaces (induction furnaces, electric arc furnaces, resistance furnaces, vacuum furnaces, etc.).
High power Power Transmission, large-scale heating systems, metal melting, and heat treatment equipment.
In recent years, it has also been used in new energy facilities such as high-pressure fast charging piles that require efficient heat dissipation.
Technical advantages:
Good heat dissipation effect: Water cooling method reduces temperature faster than traditional air cooling and increases cable current carrying capacity.
Long lifespan: Reduce temperature rise, minimize insulation aging, and extend service life.
Safe and reliable: The sealed structure is leak proof, and the outer sheath has high pressure resistance, making it suitable for harsh industrial environments.
Typical specification parameters (common models):
Rated voltage: AC 600/1000 V, DC 1000/1800 V.
Working water pressure: ≥ 0.45 MPa (some products ≥ 0.6 MPa).
Wire cross-sectional area: ranging from several hundred mm ² to thousands of mm ², can be customized according to power requirements.
There are clear standards for mechanical indicators such as minimum bending radius and geometric mean radius.
