Feature:
With long service life.Heating up fast.High thermal efficiency.Temperature uniformity. Can use vertically. When being used in the rated voltage,there is no volatile matter.It i the ne environmental protection electric heating wire.And an alternative to the costly nichrome wire.Can be customized according to customer requirements

Usage:
It is widely used in industrial furnace, household electrical appliances, infrared heater, etc.

The key properties:
1.The thickness of surface insulation resistance to oxidation layer: 5-15 μ m.
2. Insulation resistance: multimeter detection infinity.
3.The voltage-endurance of insulating single layer is greater than the alternating voltage 60 ν without breakdown.
4. The use of voltage: 6-380 ν.
5. Using temperature: Maximum1200 ºC
6. Service life: not less than 6000 hours.
7.Thermal shock performance: Electric heating element can withstand the cold and hot impact 600-6000 times without deformation.
