The plank form oranger form covers up into the far
red outside radiation machine of type

Main Technical Parameter and Performance
1、Thermal-radiating property: the max. mono-color radiating rate of elements reaches0.9, and normal total radiating rate is large than 0.8;
2、Thermal-echo time: the time from room temperature to the constant value of radiating board surface temperature is no more than 20 minutes;
3、Alternating of clod and heat resistance: after five times of alternating test of cold and heat resistance: after five times of alternating test of cold and heat resistance, no flake off or breakaway be found;
4、Unevenness of thermal-radiating surface temperature: ≤15%
5、Power deviation: under rated working voltage≤5%;
6、Cold insulation resistance: 500Vtramegger＞2mΩ
7、Heat insulation resistance: 500Vtramegger＞0.5mΩ
8、Length of life＞3000 hours.
