01Read the ratings by assembly, not by company name
Scroll sideways to compare all columns.
The manufacturer describes mining flameproof dry-type transformers for 10 or 6 kV systems, with a published capacity span of 100–2,500 kVA. The mobile-substation and transformer-for-mobile-substation descriptions extend to 4,000 kVA. Those are different catalogue entries; the higher upper rating should not be applied automatically to the standalone dry-type family.
The associated high-voltage vacuum-switch description states 10 or 6 kV and 500 A. The low-voltage protection-box description states 660–3,300 V and 800–2,000 A. These spans organise an inquiry; they are not a single assembly specification. Confirm the transformer rating, switch rating and outgoing protection arrangement together before deciding whether a proposed package matches the mine’s network.

02A mining specification needs more than a kVA value
The manufacturer labels these families as mining flameproof equipment. For the actual order, define the operating environment, installation rules and required model-specific approvals alongside the electrical duty. The enclosure, cable entries, interlocking and protection interfaces belong in the assembly specification. A catalogue category does not establish approval for every configuration or every destination country.
If the purchase is a replacement transformer section, identify the existing mobile-substation model, dimensions, connections and switching interfaces. If it is a complete assembly, identify which incoming switch, outgoing protection box and accessories are included. For bid comparison, request loss and impedance values for the proposed transformer section at the same rating and reference conditions, rather than comparing the price of unlike assemblies.

03Match the switching section before replacing it
The company introduction lists both a permanent-magnet-mechanism high-voltage vacuum switch and another high-voltage vacuum-switch category for mobile substations. Each is described at 10 or 6 kV and 500 A. Equal voltage and current labels do not establish mechanical, control or interlocking interchangeability. For a replacement, identify the installed mechanism, control supply, cable arrangement and how the switch connects to the transformer section.
The manufacturer also names its historical KBSGZY-1000–3150/10(6) mobile-substation series in the company introduction. That specific family is useful when locating an older unit's records, but it does not define the present supply range for every accessory. Send the existing assembly identification and requested replacement boundary with the inquiry. The low-voltage protection box has its own published voltage and current ranges, so its configuration must be matched to the outgoing network independently of the incoming switch rating.

04New equipment and repair are separate conversations
The company introduction describes both manufacturing and repair of domestic and overseas equipment, including historical repairs of Polish, British and German products. That supports asking about repair as a service route; it does not establish compatibility with every imported unit. A repair inquiry should include the nameplate, fault history, existing protection arrangement and available inspection records before a repair scope is agreed.
The published factory address is No. 30 Qianling Second Road, Qiandian Town, Shuncheng District, Fushun. A city-government report published on 30 April 2024 names the company among factories visited during equipment-renewal research. This is an independent dated activity record, rather than a product test certificate. For a visit connected to an order, identify the assembly and test stages you need to inspect.

Questions buyers ask
Can the 4,000 kVA upper rating be used for every listed dry-type transformer?
No. The company gives 2,500 kVA as the upper end for its standalone mining dry-type category and 4,000 kVA for the mobile-substation categories. Specify which assembly is required.
Is a mobile substation quotation the same as a transformer quotation?
No. Ask whether the incoming vacuum switch, outgoing protection box, interlocking and accessories are included. Compare the agreed assembly boundary.
Does the catalogue label establish approval in my country?
No. Identify the destination requirements and request documents for the exact proposed model and configuration.
Can a repair inquiry start without identifying the existing equipment?
A useful repair assessment needs the nameplate, fault history and interface information. Historical repair experience does not establish that any unidentified unit can be repaired.
