Is the wire resistant to corona and high voltage?

Yes, the mica tape primary insulation withstands up to 800V pulse voltages and effectively prevents corona erosion.

What materials are used for the insulation layers?

The structure includes Mica Tape for primary insulation, Polyimide (PI) for thermal reinforcement, and Polyester (PET) for mechanical protection.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trade company in Jiangyin, Wuxi, with associated companies in manufacturing. It reports ISO9001:2015 and ISO14001 certifications, environmental assessment documentation, and recent fire-drill activity. Its engineers handle customer requirement confirmation, product design, technical production support, and after-sales support, with related R&D documentation available for audit. Customization is offered from samples, designs, and full or minor requirements. However, the supplier reports no valid manufacturing-capacity contract with affiliated subcontractors, no overseas agents, branches, warehouses, showrooms, or offline trade-show participation. Reported operating and profitability indicators are zero, while no SDK, well-known-brand OEM, Fortune 500 cooperation, or overseas-service coverage is documented.

CertificationsThe supplier reports ISO9001:2015 and ISO14001 certifications. It also has a factory environmental impact assessment report, supporting documented quality and environmental-management practices.

Financial creditThe provided 2024 financial indicators report zero operating revenue, operating cost, gross profit, operating profit, gross margin, and current ratios, including multi-year revenue and margin fields. These reported figures do not demonstrate financial strength or liquidity.

R&D capabilityThree R&D engineers are reported, with responsibilities covering customer-request confirmation, new-product design, and technical support. Design input, output, review, verification, and validation documents are available for audit, but no SDK is available; the evidence supports basic product-development capability rather than advanced software integration.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its engineers also design new products and confirm customer requirements, providing direct support for customized development.

Client casesThe supplier reports no OEM service for well-known brands and no cooperation with Fortune 500 companies. Although repeat-buyer preference is reported at 80%–100%, no named customer cases or independently described project references are provided.
