400*500*160mm explosion proof junction box terminal box with cable
gland
Features:
1.Explosion proof junction box is used in the circuit below 380V,
as the wiring of various electrical equipment, and is used for
branching.
2. The material is glass fiber unsaturated resin, stainless steel,
cast aluminum alloy enclosure, surface spray, beautiful appearance.
3. IIB grade uses flat joint surface explosion-proof, reliable
explosion-proof performance;
4. IIC class uses the joint surface of the joint to prevent
explosion, the explosion-proof performance is reliable, and the
protection ability is good;
5. the direction of the inlet port is varied, the inlet port
can be arbitrarily selected according to user requirements and the
cable sealing joint of DQM series can be directly equipped
according to user requirements
6.the inlet box of the junction box is usually made of inch pipe
thread. It can also be machined into metric thread or NPT thread
according to user requirements, but it must be noted when ordering

Application:
1. Can be used in hazardous areas: Zone 1 and Zone 2 .
2. Can be used in explosive gas atmospheres of Category IIA and II
B IIC where the temperature classification is T6.
3. Two type of Ex d(IIB) and complex(IIC).
4. Flammable dust atmosphere.
5. Widely using in the fields of oil, chemical industry ,
spaceflight ,war industry and so on.
Maintenance:
1.The junction box shall not be dismantled at will. After the
pre-stage power supply is disconnected during maintenance, the
cover can be opened for maintenance. The explosion-proof joint
surface should not be damaged during maintenance. After the
maintenance, the explosion-proof joint surface is cleaned and
coated with 204-1 anti-rust oil. After the joint is completed, the
bolts (nails) of each part can be used only after being fastened.
2. The junction box should be inspected regularly. It is found that
the sealing ring of the cable introduction device is deteriorated
and other parts should be replaced in time.
