Safety reinforced shell,inside are mounted Explosion-separate type elements
The shell mould-shaped by glass fiber reinforced and unsaturated ployster
elegant-insisting impact-withstanding and perfactions of corrosion-proofing,
electro static-insisting impact-withst and ding and perfact thermal reliability.etc
The explosion-separate type,control switchwith compact structure,
steady property,small volume,high capacity,and long-trmlife has several
functions to e selected freely.Explosion-proofing button by ultrasonic
encapsulation arts,ensuring the dependable combining intension The function
of it can combine freely in two units.The explosion-proof indicator by special
design,using within the AC voltage soope of 220V-380V generally.
All the exposed fastening pieces are made of stainless steel and
Of anti-lost type,which be convenient to maintaining.
The joint of shell and cover is the form of deviou-labyringhian truture,Water-
proof,dust-proof.
