HCL2 (3)-j4 type high temperatureConstant Power Electric TropicsThe working principle structure, the application HCL2 (3)-j4 type is same, may use in the factory one area, the second area explosive gas mixture T3-T6 group place. The main difference is: High temperature resistance grade: Medium maintenance temperature ≤250℃, insulating material for high-temperature composite materials and PFA fluorine plastic. Insulating layer material up to 260 ℃, its main specifications, technical indicators see the following table:
