Asiantool A7HV NM High Voltage Multi Conductor

Description

The A7HV NM is the high-voltage specialist in the 7-conductor family. The “HV” designation indicates that the internal spacing and dielectric materials are optimized to prevent arcing and leakage at higher voltage thresholds.

By using liquid metal instead of traditional carbon brushes, the A7HV NM maintains a constant “wet” contact with an extremely low resistance of < 1 mΩ. This technology eliminates the electrical noise, carbon dust, and mechanical wear associated with standard slip rings. It is an ideal solution for powering rotating industrial heaters, multi-phase motors, or complex automated carousels that require both high-power delivery and signal integrity.

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 higher voltage peaks (up to 500V AC/DC) across all 7 poles.
Liquid Metal Technology: Provides an ultra-stable, “silent” electrical connection with near-zero electrical noise, protecting sensitive PLC and sensor data.
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, making it safe for use in food processing, medical manufacturing, and environmentally sensitive zones.
High Current Capacity: Supports up to 30A per pole, allowing for substantial power transfer in a relatively compact form factor.
Low Rotating Torque: Requires very little force to rotate, which reduces the thermal and mechanical load on the drive system.
