Waterproof and explosion-proof end terminal box
Explosion-proof tail-end box is manufactured in accordance with the relevant provisions of the national standard GB3836.1-2000, GB3836.3-2000 "Explosion-proof electrical equipment for explosive environments, general requirements, increased safety electrical equipment "e"" equipment. Explosion-proof level Exe Ⅱ T4, suitable for the temperature group of T1 ~ T4 of explosive gas mixtures in Zone 1 and Zone 2 of the factory.
1．Model and structure
Explosion-proof end box is divided into two boxes, it is used for the end of the electric tropical, so that the end of the electric tropical and the outside world, the lower box cavity has a partition, so that the end of the electric tropical bus bar is reliably separated.
Explosion-proof terminal junction box is used for the end of the electric heat tape, so that the break of the electric heat tape and the outside world reliable isolation. Its shell material is made of PMC plastic.
Main technical parameters：
Rated voltage: -220V/380V
Protection grade: IP54
(1) found that the junction box shell deformation, cracks or damage, should stop using, replace the new parts.
(2) The installation should prevent a short circuit between the core wire and the electric heating wire and the outer braided copper wire.
Warning：The two wires at the end of the electric heat tape should be separated
