AI-Powered supplier vetting

SummaryThe supplier presents itself as a professional manufacturer in the electrical and electronics sector, with a 17,316 m² manufacturing plant, R&D, production, sales, and after-sales functions, plus stated quality-management controls. It offers broad customization and ODM services, uses CNC laser cutting, shearing, and bending equipment, and has documented procedures for finished-product inspection, service assessment, corrective actions, and complaint handling. Its business scope includes distribution and control equipment, metal structures, charging piles, charging infrastructure, and related power equipment. However, it reports no new products in the past year, no SDK, no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Export-start information is confidential, overseas service coverage is recorded as zero, and the financial data provided are coded values without sufficient interpretable evidence. The materials do not establish certifications or specific customer cases.

Supplier typeThe supplier is identified as a professional manufacturer serving the Electrical & Electronics sector, with R&D, production, sales, and after-sales functions. Its stated business scope covers control equipment, metal structures, charging piles, charging infrastructure, and power facilities.

After-Sales capabilityThe company states that it provides after-sales service and has written procedures with records for service assessment, corrective and preventive actions, and customer complaints. However, it reports no overseas warehouse, showroom, agent or branch, and overseas service coverage is recorded as zero, limiting demonstrated international service reach.

Production capacityThe supplier reports a 17,316 m² manufacturing plant, CNC laser cutting, shearing and bending machines, standardized finished-product inspection instructions, and documented service procedures. It also reports peak- and off-season lead times within 15 workdays, supporting a positive assessment of stated production capability.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and separately states ODM availability. These repeated declarations provide direct evidence of broad customization capability.

Product Q&A

Q:What are the applicable voltage levels and capacity range of the box-type substation?

It is conventionally adapted to 10kV on the high-voltage side and 0.4kV on the low-voltage side, with a rated capacity ranging from 50kVA to 2500kVA. Non-standard customized expansion is supported to meet special needs.

Q:Which environments can the protection class of the box-type substation adapt to?

The standard protection class is IP54, which is dustproof and splashproof, suitable for outdoor, industrial park and other scenarios; optional IP55 enhanced protection is available to cope with harsh environments with heavy rain and excessive dust.

Q:How long is the installation cycle of the box-type substation?

Adopting factory prefabricated production, on-site only needs to complete foundation fixing, wiring and commissioning. The overall installation cycle is only 24~48 hours, which is much shorter than that of traditional civil engineering substations.

Q:What does the intelligent operation and maintenance function of the box-type substation include?

It supports real-time collection of 12 key data such as voltage, current and temperature, is equipped with RS485 and Ethernet interfaces, compatible with Modbus and IEC 61850 protocols, and can be remotely monitored and controlled through mobile APP or computer client.

Q:Can the box-type substation be compatible with the grid connection of new energy sources such as photovoltaic and wind power?

Yes, it is equipped with anti-islanding protection function as standard, and can support the access of new energy power generation units up to 2500kVA, meeting the grid connection needs of distributed power sources.
