1、 Basic technical parameters

1. Explosion-proof marking：
   • Indicate the explosion-proof level and applicable scope of the distribution box, such as ExdIIBT4, ExdeIICT6, etc.
2. rated voltage：
   • Usually AC220V/380V, but other voltage levels can also be customized according to customer needs.
3. rated current：
   • The rated current of the main circuit and the rated current of the branch circuits need to be determined according to customer requirements.
4. Protection level：
   • Such as IP54, IP55, IP65, etc., indicate the protection ability of the distribution box against water and dust.
5. corrosion resistance grade：
   • WF1, WF2, etc. represent the anti-corrosion performance of the distribution box.

2、 Box material and structure

1. material：
   • Common materials include cast aluminum alloy, welded steel plates, stainless steel, etc. Customers can choose according to their actual needs.
2. structural form：
   • Choose wall mounted, vertical, etc. according to the installation environment and usage requirements.
3. size：
   • Determine the specific dimensions of the box based on customer needs and installation space.

3、 Internal configuration and functionality

1. Number of circuits and current：
   • The customer needs to specify the number of circuits in the distribution box and the corresponding current for each circuit.
2. Brand and model of electronic components：
   • Customers can choose the brand and model of components such as circuit breakers, switches, indicator lights, etc. according to their actual needs.
3. Special functional requirements：
   • If equipped with leakage protection function, remote control function, etc., customers need to clearly inform.

4、 Installation and wiring

1. Installation method：
   • Wall mounted, column mounted, etc., customers need to choose according to the installation environment.
2. wiring method：
   • Customers need to clearly inform them of the wiring methods such as steel pipes, cables, explosion-proof hoses, etc.
3. Import and export specifications：
   • For sizes such as DN32-DN100/G1.2-G4 inches, customers need to determine according to their actual needs.

5、 Other precautions

1. Drawings and Parameters：
   • Customers can directly provide drawings or specify specific parameters for suppliers to quote and customize.
2. Certification and Standards：
   • The customer needs to clarify the certification standards and requirements that the distribution box must meet, such as GB3836 series standards, IEC60079 standards, etc.
3. Usage environment：
   • The customer needs to clarify the usage environment of the distribution box, such as explosive gas environment, combustible dust environment, etc., so that the supplier can choose the appropriate explosion-proof level and material.

In summary, the data required for customizing explosion-proof power supply maintenance boxes includes basic technical parameters, box material and structure, internal configuration and function, installation and wiring, and other precautions. Customers need to choose and clarify according to their actual needs and usage environment, so that suppliers can produce explosion-proof power supply maintenance boxes that meet the requirements.
