FDP2-J4型高溫恒功率電熱帶,其工作原理,産品結構及應用與FDP2-J3型恒功率電熱帶相同,所不同的是其絕緣材料採用瞭(le)耐高溫防水玻璃纖維和耐溫高於(yú)F46的PFA氟塑料,流體維持溫度可達180℃~205℃,它尤其适合瀝青、重粘油管線伴熱,該産(chǎn)品可用於(yú)工廠一區、二區爆炸場所。
FDP2-J4 Hi-temp heating cable properties is similar to FDP2-J3,The difference is that the insulation material is Hi-temp water proof fiberglass and PFA fluoropolymer. It is suitable for industrial application where temperature excursions to 205℃ or process temperature maintenance to 180℃~205℃.Particularly use in maintenance temp such as pipeline of Pitch,crude oil.It is applied in ordinary(non-hazardous)areas and division 1,2 hazardous(mixed gas)Class locations.
