The heater core is made of iron chromium aluminum alloy wire or nickel chromium alloy wire as heating body, using natural mica or artificial powder mica plate as insulation layer, heating core can be made into a circle, plate, ring, cuboid and various special-shaped products. It has good aging resistance, good surface temperature uniformity, fast heating speed, long service life, automatic power off protection over overheating and other properties.

1. High temperature resistance, mica plate can withstand 600℃ high temperature;

2. Good insulation performance. Insulation resistance is greater than 100MΩ;

3. The power cord adopts high-temperature fluorine-plastic line;

4. Pressure: 1500V/1min;

5. Power deviation range: ±5%;

6. Can design temperature controller, fuse double protection.
