High Impedance Design
🛡️ 1. High Impedance for Safety

The high-impedance design is a critical safety feature, precisely tailored for vacuum furnace environments. In a short circuit event, current surge is effectively suppressed, preventing hazardous arcs and overheating, safeguarding equipment and operators.

🔥 2. High Current for Heating

Exceptional high-current output capability enables rapid temperature rise. By matching the electrical characteristics of heating elements, it delivers powerful current to meet high-temperature process requirements and increases production capacity.

Heating Output
Craftsmanship
💎 3. Premium Craftsmanship

Cylindrical core design with high magnetic permeability and vacuum pressure impregnation (VPI) process. Varnish penetrates winding spaces to enhance insulation. Meticulous end-sealing prevents moisture and dust intrusion.

🌍 Operation Environment
  • Altitude: Not exceeding 1000m (derating required above 1000m).
  • Ambient Temperature: -25ºC to 55ºC.
  • Relative Humidity: ≤95%.
  • Site Requirements: No bad effect on insulation, chemical deposition, dust, or erosive medium.
  • Power Quality: Sinusoidal wave and balanced three-phase voltage.
