A high-capacity, 1-conductor non-mercury rotary connector engineered to transfer substantial electrical power (up to 150A or 250A depending on the specific sub-variant) through a rotating interface with near-zero resistance.
The A1HH is designed for industrial environments where mechanical brushes would fail due to friction-induced heat, electrical arcing, or carbon dust buildup. By using a liquid metal pool, it ensures 100% surface contact across the rotating joint at all times. This results in a contact resistance of < 1 mΩ, making it ideal for high-current applications that require stable voltage delivery without the “electrical noise” common in traditional slip rings.
Asiantool’s slip rings (rotating electrical connectors) utilize special insulation, sealing, and conductive technologies. In the first three to four years of our company’s establishment, we worked in the direction of developing multi conductor models for A8H, A6H, A4H and other relevant models. At the same time, our company’s research and development team has also developed a single conductor model for theelectrical plating of 250A-A1H25S. Now, we have upgraded the product quality and introduced multi conductor models for up to 14 poles of A1430 and single heavy current conductor models up to 7500 A. for mass production.
