Asiantool A1H300PS NM Single Conductor

Description

The A1H300PS NM is built for “Power and Signal” (PS) stability at high magnitudes. While most slip rings struggle with heat and wear at high amperages, this model uses a liquid metal pool to ensure 100% surface contact at all times. This results in an incredibly low contact resistance of < 1 mΩ, preventing the heat buildup typically seen in traditional carbon brush systems.

Because it is a single-conductor unit, it is often used in pairs for DC circuits or as a primary power feed for large rotating masses where grounding or secondary phases are handled through separate units or the machine chassis.

Brand

Asiantool

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.

Features

Ultra-High Current Capacity: Rated for a continuous 300A, suitable for heavy industrial welding, plating, or large motor applications.
Liquid Metal Technology: Provides an ultra-stable connection with zero maintenance, as there are no brushes to wear out or adjust.
Eco-Friendly (Non-Mercury): Uses Gallium alloy, ensuring the device is RoHS compliant and safe for use in modern manufacturing environments.
Minimal Electrical Noise: The liquid interface ensures a “silent” electrical path, which is crucial if the power line is also used for high-frequency carrier signals.
Robust Construction: Designed to withstand the thermal expansion and mechanical stresses associated with high-current loads.
Low Rotating Torque: Despite its high power rating, the internal liquid friction is minimal, allowing for smooth rotation.
