Defrost heater

Products description: Use aluminium tube as carrier, put silicone heating wire or PVC heat wire into tube to make different shape of heat part. Separate them into two types according to aluminium tube outer diameter. It is good in seal, instant in heat conduction Applications: Apply to rated voltage bellow 250w,50-60Hz, related humidity<90%,diffuse heat after conduct electricity in an environment temperature of -30degree---+50 degree. It is generally used in refrigerator defrosting, defrost other appliance. Technical data: 1. Insulation resistance: after putting the whole tube in water for 24 hours, Insulation resistance>100Mohm, after heating for 30 min. the heated insulation resistance >20Mohm 2. Dielectric test of AC 2000v and destine current 10mA and working for 2S, the tube does not have the flashover phenomenon 3. leakage current: leakage current under 1.15 times of rated power <0.5mA 4. Power tolerance rated power of rated voltage +5%-10% 5. Down-lead intension after the test of 100N pull, the lead wire part does not get moved and ruptured.
