High Impedance Design
1. High Impedance for Safety

The high-impedance design is a critical safety feature, precisely tailored to meet stringent safety standards of vacuum furnace electrical environments. It suppresses current surges during short circuits, preventing hazardous arcs and overheating.

2. High Current for Heating

Exceptional high-current output capability enables rapid temperature rise. By precisely matching heating element characteristics, it delivers powerful current to meet high-temperature process requirements and accelerate production capacity.

High Current Capability
Premium Craftsmanship
3. Premium Craftsmanship

Cylindrical core design features compact form and exceptional magnetic permeability. Utilizing the vacuum pressure impregnation (VPI) process, insulation performance is enhanced to prevent intrusion of moisture and dust.

Operation Environment
  • Altitude: Not exceeding 1000m (derating required above 1000m).
  • Ambient Temperature: -25ºC to 55ºC.
  • Relative Humidity: ≤95%.
  • Installation: No chemical deposition, dust, or explosive medium.
  • Voltage: Sinusoidal wave, relatively balanced three-phase voltage.
