1.Class 1 div 1 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. joint surface adopts circuit seal structure, with strong waterproof and dustproof function
4, 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
5.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
6. Steel pipe or cable wiring.

Installation:
When installing, open the junction box cover and the introduction device, select the appropriate inner diameter of the sealing ring according to the outer diameter of the cable, and then pass the cable through the compression nut of the introduction device, the gasket and the sealing ring are connected to the cavity, and fasten. The compression nut seals the cable, the introduction device that does not introduce the cable replaces the cable with a plug, and tightens the compression nut. Connect the wire to the corresponding position of the terminal block, connect the grounding wire, close the cover, and fasten the cover with bolt.
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.
