Description

Technical Field

[0001] The invention belongs to the technical field of new high-performance electrical alloy materials, and particularly relates to a continuous true bright thermal composite high-frequency flexible water-cooled cable made of laminated nickel-iron alloy strips. Background Art

[0002] Water-cooled cables are mainly used in the energy conduction of medium and high-frequency electric furnaces with relatively high skin effect. Due to the relationship between the core flipping movement and the skin concentrated current, when connected to the induction furnace core, it is easy to heat up or have poor heat dissipation and cooling during operation, resulting in burnout, breakage, and open circuit. When replacing a new water-cooled cable, it takes a long time to reconnect before the induction furnace can operate. Moreover, the medium and high-frequency internal resistance of such cable conductors is large and the junction temperature is serious. Therefore, there is an urgent need to design a water-cooled cable with a flexible and fast replacement, high heat penetration rate, and extremely strong skin effect to replace it.

[0003] On the right side, we propose a continuous true bright thermal composite high-frequency flexible water-cooled cable made of laminated nickel-iron alloy strips, which increases the mechanical bearing capacity of the cable while expanding the random skin area and fusion effect of the conductor. The quick-type water-cooled cable socket and plug are coaxially connected, without the need to disassemble bolts and nuts, and the flexibility is universal without access dead ends, making the water-cooled cable more flexible, with lower internal resistance and lower energy loss, reducing the incidence of water-cooled cable failures, and at the same time, it is more convenient and fast to replace when water-cooled cable failures occur.
