E8005 explosion-proof head explosion-proof performance in line with GB3836.1-2000 "explosive gas environment electrical equipment general requirements", GB3836.9-90 "explosive environment with explosion-proof electrical equipment "m" provisions to make a pouring structure, explosion-proof logo for ExmII.T4, Suitable for plant with II.A, IIB, II C, T1 to T4 surface temperature group explosive gas or vapor and air formation of explosive gas mixture. The clever design of the watered explosion-proof head makes it have many outstanding advantages that the existing type of explosion-proof head does not have, in particular, it is small in size, light weight, very convenient installation and maintenance, has automatic function, brings convenience to construction and monitoring, and uses importshaft seal, so that the shell protection level reaches IP56 level, and takes into account the pouring-type structure, Even for a short period of time in water, it works.This reflects the development trend of explosion-proof head.
