How do you package transformers for transport?

LCL shipments use sturdy wooden crates with moisture-proofing. FCL shipments have transformers securely fastened inside the container to withstand ocean transport.

What is the warranty period?

We offer a 12-month warranty from the date of manufacture. Extended warranties are available for major components.

How do you provide technical support if the product malfunctions?

We provide remote guidance via phone, email, or video. On-site service by engineers is available if required (additional fees apply), along with long-term spare parts supply.

AI-Powered supplier vetting

SummaryThe supplier is a combined company with manufacturing, export, service, quality-control, R&D, and sustainability capabilities. It performs 100% finished-product inspection and holds ISO9001:2015, ISO45001:2018, ISO14001, CCC, and CE certifications. It supports extensive customization and has OEM experience for popular brands, but does not provide ODM services, has no available SDK, and lacks R&D audit documentation and new product development evidence from the past year. Export sales represent 41%–50% of total sales, while overseas service infrastructure is limited: no overseas agents, branches, warehouses, or showrooms. Production-related controls include inventory capability and one-month lead times, but there is no valid manufacturing-capacity contract with affiliated subcontractors and no written service-capability procedures or inspection records. Financial records are indicated for 2022–2024, but the slices do not provide sufficient evidence to assess financial strength.

Supplier typeThe supplier is explicitly identified as a combined company rather than an offshore company. Its described business scope covers manufacturing, export trade, service, quality control, R&D, and sustainable development capabilities, indicating an integrated supplier profile.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, along with CCC and CE product-certification capability. These are explicit certification-related credentials supporting quality, occupational safety, environmental management, and product compliance.

After-Sales capabilityThe supplier has in-stock service capability and has participated in the South Africa Power Exhibition, but it reports no overseas agents or branches, no overseas warehouse, no overseas showroom, and service coverage in zero countries. This demonstrates limited overseas after-sales infrastructure.

R&D capabilityThe supplier has CAD capability and engineers can develop products according to customer voltage, capacity, appearance, material, and size requirements. However, it has no available SDK, no R&D audit documentation, no new products reported in the past year, and no ODM service, limiting evidence of independent innovation.

Production capacityThe supplier operates automatic winding and cutting equipment, performs 100% finished-product inspection, maintains inventory capability, and reports one-month peak- and off-season lead times. Nevertheless, it has no valid manufacturing-capacity contract with affiliated subcontractors, and its service-capability assessment has no written procedures or records.

Customization capabilityThe supplier explicitly offers customization from designs, full customization, minor customization, and flexible customization. Its R&D responsibilities also cover customer-defined voltage, capacity, appearance, material, and size, providing direct evidence of broad customization capability.

Client casesThe supplier explicitly reports OEM service for popular brands, export sales representing 41%–50% of total sales, and participation in the South Africa Power Exhibition. These indicate brand-OEM and export-market experience, although no specific customer names, project details, or case outcomes are provided.

Product Q&A

Q:What types of transformers do you primarily manufacture?

We mainly produce oil-immersed transformers for outdoor and industrial use, and dry-type transformers for indoor, commercial, and high-safety requirement locations.

Q:Are windings made of copper or aluminum?

We offer both. Copper provides higher conductivity and efficiency but costs more. Aluminum is a lower-cost, lighter, fully qualified alternative.

Q:What is the minimum order quantity?

For standard products, the MOQ is 1 unit. For customized products, the MOQ is determined through negotiation based on specific specifications.

Q:What payment methods do you accept?

We accept T/T (Telegraphic Transfer), typically with a 50% advance payment and the remaining 50% paid before shipment.

Q:What is the delivery lead time?

Standard small transformers take 15-30 days. Large or custom transformers take 45-90 days or longer, depending on quantity and type.
