model implication



1. the outer casing of the product is cast aluminum alloy zl102. adopting a one-time die-casting process, the surface is smooth, the appearance is beautiful, the internal structure is high in density, the impact resistance is strong, and the outer casing has good explosion- proof performance.

2. after the surface of the outer casing is deburred by industrial robots and high-speed shot blasting, the advanced automatic high-pressure electrostatic spray and heat-curing line technology is adopted, and the plastic layer formed on the surface of the shell has strong adhesion and good corrosion resistance.

3. when the main cavity is an increased safety type, the explosion-proof indicator light, button, voltmeter, ammeter, potentiometer and transfer switch are installed inside.

4. when the main chamber is an explosion-proof type enclosure, it is equipped with common indicator lights, buttons, voltage, ammeter, potentiometer and transfer switch for industrial use.

5. outdoor products can be equipped with rain cover according to user requirements.

6. the sealing strip adopts two-component polyurethane primary casting foaming process, which has high protection performance.

7. when the single-chamber explosion-proof control box incoming cable is directly introduced, an explosion-proof stuffing box should be used.

8. all exposed fasteners are made of stainless steel.

9. the cable incoming direction can be made into various forms such as up and down according to user requirements.

10. the inlet and outlet ports are usually made of pipe threads, and the cable clamping and sealing device is arranged. it can also be made into metric thread, npt thread, etc. according to the requirements of the user's site.

11. steel pipes and cable wiring are available.
