AI-Powered supplier vetting

SummaryThe supplier operates in power transmission, distribution, monitoring, control, electrical equipment, instruments, software, and related technical services. It reports more than 22 years of core-team development and nationwide recognition, while export activity began one year ago and exports represent 51%–70% of sales. The supplier provides extensive customization and 3D software design services, but reports no new products in the past year and has only one R&D engineer. Quality-related certifications include ISO 9001:2015 and CE. Quality assurance is stated, although finished products are checked by packing staff, and no written corrective-action or complaint-handling procedures are reported. The supplier has no stated inventory, overseas warehouse, or overseas showroom capability. No Fortune 500 cooperation is reported, and the available financial figures are not sufficient for assessment.

Supplier typeThe supplier is positioned as a power and electrical equipment provider, with business scope covering power transmission and distribution equipment, intelligent monitoring and control equipment, instruments, electrical components, technical services, repairs, and related software and hardware. The core team is reported to have more than 22 years of development experience, indicating an established industry focus.

CertificationsThe supplier reports an ISO 9001:2015 management-system certificate and CE product compliance certification. These certifications provide explicit evidence of formal quality-management and product-compliance credentials.

After-Sales capabilityThe supplier reports no written procedures or records for corrective and preventive actions or effective customer-complaint handling. It also reports no inventory capability, overseas warehouse, or overseas showroom, limiting documented after-sales and overseas service support.

R&D capabilityThe supplier has technical development and R&D-related business scope and provides 3D software design services, but it reports no new products during the past year and only one R&D engineer. The evidence shows some technical capability but does not demonstrate strong recent product innovation.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also provides 3D software design services. These statements directly support broad customization capability.

Product Q&A

Q:What is the warranty period for the transformer?

We provide a one-year warranty (12 months since customer receive & use the machine). The manufacturer also guarantees to provide life-long paid maintenance services for the product.

Q:What are the main features of the core and winding?

The core is made of high permeability magnetic grain oriented cold rolled silicon steel sheet with a multi-stepped step design. The winding adopts corrugated oil passage, no immersion paint process, and uses concentric coils.

Q:How does the transformer handle temperature changes?

The corrugated fins have a 'breathing' function that compensates for the volume change of transformer oil caused by temperature rise and fall, eliminating the need for an oil storage cabinet.

Q:Is customization available for this transformer?

Yes, customization is available. Options include sealing technology (Fully Sealed, No Conservator) and energy efficiency improvements (Low No-Load and Load Losses).

Q:What safety protection devices are included?

Transformers from 30-2000kVA are equipped with a pressure relief valve. A gas relay with alarm and trip terminals can be installed according to user requirements. Oil temperature measuring devices are also available.
