Asiantool A3V4S NM High Voltage Multi Conductor

Description

The A3V4S NM is designed for complex rotating systems where multiple types of electrical loads must be transferred through a single, compact interface. Unlike standard slip rings, the “V” and “S” series designations typically indicate specialized High Voltage and Signal/Power combination capabilities.

By using liquid metal technology, the A3V4S NM achieves near-zero electrical noise and a contact resistance of < 1 mΩ. This ensures that even at high voltages, there is no arcing or signal degradation, making it perfect for transmitting sensitive data like thermocouples or video alongside high-power industrial loads.

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

hybrid Conductor Poles: Features a 3-pole configuration capable of handling different current ratings (30A/4A) for versatile power and signal mixing.
Non-Mercury Technology: Uses Gallium alloy for a maintenance-free, eco-friendly connection that eliminates the risks of mercury contamination.
High Voltage Integrity: Built with reinforced insulation to support 500V AC/DC, preventing electrical leakage in high-power applications.
Maintenance-Free: No mechanical brushes to replace, resulting in zero carbon dust and a significantly longer service life than traditional slip rings.
Ultra-Low Electrical Noise: Provides a “wet” contact that is electrically silent, essential for precision sensors and high-speed data.

Applications

Heating Rollers: Supplying high-voltage power to rotating rollers in laminating or textile machines.
Packaging Equipment: Transmitting power to rotary sealing bars while receiving temperature sensor feedback.
Wind Turbines: Providing pitch control power and signal transmission across the nacelle.
Robotic Arms: Managing motor power and encoder signals in high-torque rotating joints.
