Asiantool A3HV NM High Voltage Multi Conductor

Description

The A3HV NM is the high-voltage specialist of the 3-conductor family. The “HV” designation indicates that the internal spacing and dielectric materials are optimized to safely manage higher voltage thresholds (up to 500V) without the risk of electrical arcing or leakage between the three poles.

Unlike traditional slip rings that use carbon brushes—which create dust, wear out, and generate electrical interference—the A3HV NM uses liquid metal to maintain a constant “wet” contact. This results in an exceptionally low contact resistance (< 1 mΩ), making it ideal for transmitting sensitive sensor data 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

High Voltage Integrity: Engineered with superior insulation to safely handle high voltage peaks across all 3 poles.
Liquid Metal Technology: Provides an ultra-stable connection with near-zero electrical noise, protecting sensitive PLC and data signals from interference.
Maintenance-Free: No brushes to replace and no lubrication required for the entire lifespan of the device, ensuring maximum machine uptime.
Eco-Friendly (Non-Mercury): Uses Gallium alloy, ensuring the device is safe for global use and meets environmental regulations like CE RoHS.
High Current Capacity: Supports up to 30A per pole, allowing for efficient power transfer in a compact form factor.
Low Rotating Torque: Requires minimal force to rotate, which reduces the mechanical load on the system’s drive motor.
