Frequently Asked Questions (FAQ)
Q:
What options are available for the substation shell housing material?
The substation shell can be constructed from a variety of materials including cold rolled steel plates, stainless steel plates, composite color plates, aluminum alloy plates, or glass fiber reinforced cement.
Q:
Can this substation be customized for non-standard working environments?
Yes. If your operating environment does not meet our standard service conditions (such as high altitude above 1000m or extreme temperatures), we can design and manufacture customized solutions tailored to your specific requirements.
Q:
What types of transformers are compatible with the transformer unit?
The unit is designed to accommodate S9-M and S11-M oil-immersed transformers, as well as SCB dry-type transformers, depending on your system specifications.
