HCLtwo (three) - Jfour type high temperatureConstant power electric heating beltThe working principle, structure, and application of HCLtwo (three) - Jfour are the same, and can be used in explosive gas mixture Tthree-T6 groups in Zone 1 and Zone two of the factory. The main difference is that it has a high temperature resistance level: the medium maintains a temperature of ≤ twofifty ℃, and the insulation material is high-temperature composite material and PFA fluoroplastic. The insulation layer material can withstand up to twosixty ℃, and its main specifications and technical indicators are shown in the following table:
