Asiantool A4HV High Voltage Multi Conductor

Description

The A4HV is designed for industrial automation where electrical “noise” must be eliminated. By replacing mechanical brushes with liquid metal, it achieves a contact resistance of < 1 mΩ, effectively removing the signal jitter, friction, and carbon dust associated with traditional slip rings.

The “HV” designation highlights its High Voltage architecture, featuring reinforced internal insulation barriers to prevent arcing between the four independent channels, making it safe for 480V industrial power grids.

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

4-Pole Configuration: Ideal for 3-phase AC power plus a dedicated ground/neutral, or two independent high-voltage DC circuits (+/-).
High-Voltage Rating: Rated for up to 500V AC/DC, allowing it to safely interface with standard industrial power systems.
Liquid Metal Technology: Provides zero maintenance and a near-infinite signal integrity lifespan compared to contact-based slip rings.
Eco-Friendly (Non-Mercury): Uses a safe Gallium alloy, ensuring RoHS compliance for food-processing, medical, and cleanroom applications.
Low & Stable Torque: Maintains a constant, low rotating torque (2000 gm-cm), reducing the mechanical load on drive motors.
Superior Insulation: Features an insulation resistance of > 50 MΩ, critical for high-voltage safety and signal separation.

Applications

Heated Rollers: Delivering 3-phase power to internal heaters while providing a dedicated ground path for safety.
Laminating Machines: Managing the high-voltage power for rotating pressure and heat rollers.
Packaging Equipment: Powering high-draw sealing bars and conveying PLC timing or sensor signals.
Robotic Bases: Providing the primary electrical link for rotating robotic workstations and automated turntables.
Wind Turbines: Used in pitch control systems where motor power and ground/neutral must pass through a single axis.
