Do you keep products in stock?

Normally no. All products are produced based on your order quantity.

What information is needed for custom transformers?

Technical drawings and specification documents are best. You can also provide details such as winding material, input voltage, and rated capacity.

The supplier reports two quality-control staff, ten quality-control test items or equipment units, and two R&D engineers. It offers extensive customization, ODM services, and OEM services for known brands, and reports new products within the past year. Production equipment covers transformer-related processing, winding, drying, oil filtration, pouring, cutting, and forming. Financial and cash-flow information is indicated for 2021–2023, but no financial figures are provided. Overseas service coverage is recorded as zero countries, although multiple quotation and payment terms are accepted. No Fortune 500 cooperation...

Supplier typeThe supplier is a manufacturer, seller, and maintenance provider for transformers, distribution cabinets, and electrical equipment, while also selling related accessories, lubricants, wires, and cables. This indicates a directly relevant electrical-equipment supplier with production and maintenance activities.

CertificationsThe supplier reports ISO9001:2015 and ISO14001:2015 certifications, plus ISO45001:2018 and ISO14001 under its management and sustainability-related certifications. Product compliance is listed only as “Others,” so the management-system certification evidence is stronger than the product-standard evidence.

After-Sales capabilityAfter-sales service is an assigned responsibility of the two R&D engineers, and the supplier reports written, recorded procedures for service capability assessment, complaint handling, and corrective and preventive actions. However, overseas service coverage is recorded as zero countries, limiting evidence of international after-sales reach.

R&D capabilityThe supplier reports new products within the past year, ODM capability, customization from samples and designs, and two R&D engineers responsible for new-product R&D and after-sales service. It has no available SDK, but the stated product-development evidence supports an active basic R&D capability.

Production capacityThe supplier lists a broad set of transformer-production equipment, including silicon-steel slitting, CNC punching, winding, vacuum oil filtration, drying, pouring, cutting, shearing, and bending machinery. It also reports written warehouse-control procedures and records, although production capacity, throughput, and equipment quantities are not provided.

Customization capabilityBoth the R&D and design-capability records state customization from samples, customization from designs, full customization, minor customization, and flexible customization. The supplier also reports ODM services, providing explicit evidence of broad customization support.
