GWL high temperature series self-limiting temperature electric heating cable Technical indicators:
Standard color: red;
Temperature range: maximum working temperature 130 ± 5 ℃; maximum exposure temperature 150 ℃;
Construction temperature: minimum -40 ℃;
Thermal stability: After cycling back and forth from 10 ℃ to 149 ℃ for 300 times, the heating value of the heating cable is maintained above 90%.
Bending radius: 38.5mm at -20 ° C; 49.0mm at -30 ° C;
Silicone rubber flat cable Insulation resistance: When the length of the heating cable is 100m and the temperature is 75 ° C, the minimum value of the insulation resistance is 20MΩ, which is shielded or explosion-proof. At room temperature, use 2500VDC to shake between the shield and the conductive core for 1 minute. The minimum value is 20MΩ.
