A high-capacity, 1-conductor non-mercury rotary connector designed for industrial power applications. It is engineered to handle significant current loads while maintaining near-zero contact resistance.
The A1H90PS is part of the high-power “PS” series. Traditional slip rings often fail at high amperages due to brush wear, heat, and sparking. This unit uses a liquid metal interface that provides a massive contact surface area relative to its size, enabling it to carry 900 Amperes continuously while rotating, with a contact resistance of < 1 mΩ.
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.
