Product Overview

This high-power rectifier is widely used in metallurgical, chemical, papermaking, graphite, and military industries, providing DC power for electrolysis processes of aluminum, zinc, copper, magnesium, sodium, lead, manganese, caustic soda, chlorine dioxide, etc. It also serves as a heating power supply for DC arc furnaces, graphitization furnaces, mineral smelting furnaces, steel wire heating, and high-voltage transmission line de-icing.

Product Features

  1. Low Vibration & Noise Design

    • Conductive busbars inside the rectifier cabinet are insulated with epoxy-coated I-beams, ensuring minimal vibration and noise.

  2. Enhanced Insulation Performance

    • Internal busbars are supported by high-strength epoxy resin boards, significantly improving insulation reliability.

  3. High-Efficiency Cooling System

    • Rectifier components utilize single-press-formed copper heat sinks, ensuring optimal contact with uniform surface pressure, reducing contact resistance and component loss.

  4. Isolated Overvoltage Protection

    • Over-voltage protection devices are physically isolated from the main circuit, preventing main cabinet failures caused by protection device damage and enhancing safety.

  5. Space-Saving Integrated Design

    • The rectifier system supports integrated modular packaging, combining the main rectifier cabinet, control cabinet, distribution cabinet, DC disconnect switch, and pure water cooler into a single sealed container. This reduces footprint and prevents dust ingress.

  6. Adaptability to Extreme Environments

    • For Arctic or extreme heat regions, an adaptive thermal management system is optional, including built-in air conditioning and thermal insulation layers. This maintains a constant internal temperature regardless of external conditions.
