1.the first thing is that you must be clear about your needs, according to your actual situation, choose the most suitable distribution cabinet type. This is the most basic criterion that should be followed in the selection process.
       2. There are four main types of distribution box materials for the explosion-proof type of the box shell
of the distribution box, including aluminum alloy, stainless steel, carbon steel and engineering plastics. In the selection, according to the actual construction needs to be selected, but no matter what kind of material is selected to make the box, the box must adhere to the complete.

3. look at the distribution box box standard domestic distribution box types are many, different box structure has different types, each standard box in the structure, technical parameters have different requirements, applicable occasions and prices are also different. Explosion-proof distribution box type and selection

4. look at the distribution box equipment base of high-quality distribution box in the air switch base are smooth and have a sufficient space to play, in the selection should pay extra attention to this.

5. Look at the bus of the distribution box, the wiring bus in the distribution box should be separated from the setting up of change, protect the grounding wire, the phase line, and be intact, with good insulation function to ensure the safety of daily use.

6. The load and parameters of the distribution box will vary greatly in the environment of the electricity load, so it is necessary to recognize the type and standard of the distribution box according to the nature and use of the load.

7, look at the brand In addition, the purchase of explosion-proof distribution boxes should also look at the brand, and select products with high visibility, good reputation, safety and reliability.

8. Look at the price of explosion-proof distribution box composed of explosion-proof cabinets, components (refers to circuit breakers, AC contactors, thermal relays, etc.), surface explosion-proof components (explosion-proof lights, explosion-proof buttons, etc.), accessories, wires and other auxiliary materials, labor costs, etc.

9. The manufacturer of the explosion-proof distribution box of the component should provide technical drawings. If there is no technical drawing, the requirements inform the specific technical requirements. The demand tells us which components are installed in the explosion-proof distribution box, and there are no requirements for the brand of the components. The main switch is not required, the requirements of the main switch are all switches with leakage maintenance is still the main switch with leakage maintenance. Understanding these parameters, we can make a general quotation for the explosion-proof distribution box. 10, look at the explosion-proof certificate and explosion-proof level Finally, we must pay attention to a high-quality explosion-proof distribution box must have an explosion-proof certificate, which is an important indicator of the strength of the distribution box manufacturer and the quality of the product! In addition, the explosion-proof distribution box explosion-proof grade has IIB and IIC grades, and the explosion-proof symbol should be seen with the manufacturer's requirements when purchasing.
