AI-Powered supplier vetting

SummaryWenzhou Yuanda Electrical Equipment Co., Ltd. is a China-based manufacturer established in 1993, with 280 employees, more than 10 production lines, 50 quality-control staff, and stated output capacities for voltage stabilizers, miniature circuit breakers, and AC contactors. The supplier reports ISO 9001:2015 certification and product certifications including UL, CE, and 3C, as well as design patent technology. Its stated processes include advanced design software, testing equipment, and controls from raw-material procurement through finished products. However, the available information does not verify contract manufacturing, inventory, overseas services, ODM/OEM, SDK, environmental, or fire-drill capabilities. No customer cases or financial-strength evidence is provided. The audit record identifies TUV Rheinland and a valid report period, but the audit result is recorded as “0” without an explained interpretation.

Supplier typeThe supplier is explicitly identified as a manufacturer and a limited company located in Zhejiang, China. It has operated since 1993, supporting classification as an established manufacturing supplier.

CertificationsThe supplier reports ISO 9001:2015 certification and product certifications including US UL, EC CE, and 3C; it also states that it has held an industrial production permit and received export-advanced-enterprise recognition for three consecutive years. A TUV Rheinland audit report is listed with dates from November 4, 2025 to November 3, 2026, although the recorded audit result of “0” is not explained.

After-Sales capabilityThe supplier states that its marketing center provides comprehensive pre-sale, in-sale, and after-sale service to customers worldwide. However, overseas warehouse, showroom, and overseas agent or branch capabilities are all marked unknown, so the depth and delivery model of after-sales support cannot be fully verified.

R&D capabilityThe supplier reports using PROE/CAD and other design software, integrating decades of low-voltage electrical manufacturing experience, and holding product design patent technology. ODM, SDK, private-mold, 3D-design, and new-product R&D capabilities are marked unknown, limiting confirmation of broader innovation services.

Production capacityThe supplier reports more than 10 production lines, 50 quality-control staff, and stated annual capacities of 1,000,000 voltage-stabilizer boxes, 5,000,000 miniature circuit-breaker boxes, and 2,000,000 AC-contactor bags. It also describes testing equipment and process controls from raw-material procurement through finished production, providing explicit evidence of substantial production and quality-control infrastructure.

Product Q&A

Q:What is the main function of a power transformer?

The core function of a power transformer is to change the voltage level of alternating current (AC) in power systems. It can step up low voltage to high voltage for long-distance power transmission (reducing line loss) or step down high voltage to low voltage for industrial production and residential use. Meanwhile, it ensures electrical isolation between the input and output circuits to improve system safety.

Q:What are the common types of power transformers classified by cooling method?

Power transformers are mainly divided into two categories based on cooling methods: Oil-immersed transformers: The core and windings are immersed in insulating oil, which achieves cooling and insulation effects. They are widely used in outdoor power grids, with advantages of large capacity and low cost. Dry-type transformers: Insulating materials (such as epoxy resin) are used for encapsulation. They feature high fire resistance, low noise, and are suitable for indoor scenarios like high-rise bu

Q:What is the degree of protection for this transformer?

The standard degree of protection is IP54 for indoor use. An optional IP65 protection grade is available for customized requirements.

Q:What certifications does the company hold?

The company holds ISO 9001 Quality Management System certification and international approvals including CE, CB, UL, ETL, and CCC.

Q:What is the minimum order quantity?

The minimum order quantity is 1 Pc.
