Asiantool A3HV High Voltage Multi Conductor

A high-capacity, 3-conductor non-mercury rotating connector designed for high-voltage environments (up to 500V). It is the standard choice for 3-phase AC power transmission or high-amperage DC circuits requiring a stable, low-resistance connection.

Description

The A3HV is engineered for industrial automation where electrical “noise” and voltage drops must be eliminated. By replacing mechanical brushes with a pool of liquid metal, it achieves a contact resistance of < 1 mΩ. This ensures 100% surface contact at all times, removing the signal jitter and carbon dust contamination associated with traditional slip rings.

The “HV” designation highlights its High Voltage architecture, featuring reinforced internal insulation barriers to prevent arcing between the three independent channels, even when operating at peak industrial voltages.

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

  • 3-Pole Configuration: Perfectly suited for 3-phase AC power transmission (L1, L2, L3) or high-voltage DC (+ / – / Ground).
  • High-Voltage Rating: Rated for up to 500V AC/DC, making it compatible with 480V industrial power grids.
  • Liquid Metal Technology: Provides zero maintenance and a significantly longer lifespan than brush-type connectors, as there are no parts to “wear down.”
  • Eco-Friendly (Non-Mercury): Uses a safe Gallium alloy, ensuring the unit is RoHS compliant for food-grade, medical, and high-tech manufacturing.
  • Low & Stable Torque: Requires minimal force to rotate (1500 gm-cm), which reduces the mechanical load on drive motors and prevents premature wear.
  • Superior Insulation: Features an insulation resistance of > 50 MΩ, ensuring high-voltage safety and separation between the three conductive paths.

Applications

  • Heated Rollers: Delivering 3-phase power to internal heating elements in industrial laminators and calenders.
  • Packaging Machinery: Powering rotating heat-sealing bars and heavy-duty cutting heads.
  • Rotary Welding: Carrying high-current welding power in automated robotic cells.
  • Wind Turbines: Used in pitch control systems where 3-phase motor power must pass through the rotating hub.
  • Plating Tanks: Delivering high-amperage DC power to rotating electrodes in electroplating lines.
