AI-Powered supplier vetting

SummaryThe supplier operates in power electronic components, optical fiber and optical cable manufacturing and sales, technical services, and related technology development. It reports ISO9001:2015, ISO45001:2018, ISO14001, and ISO50001 certifications, documented quality and service procedures, complaint-handling and corrective-action records, and an environmental impact assessment. The supplier provides extensive customization and ODM services, has introduced new products within the past year, and supplies OEM services to well-known brands. Manufacturing-related evidence includes valid contracts with associated subcontractors, inventory capability, finished-product inspection instructions, and a reported one-month lead time in both peak and off-season periods. Export experience is stated as 14 years, with exports accounting for 21%–30% of sales and access to overseas agents or branches. However, no overseas warehouse or showroom is available, no SDK is available, and the provided financial figures are zero;...

Supplier typeThe supplier is a manufacturer and seller of power electronic components, optical fibers, and optical cables, while also providing technical services and technology development, consultation, transfer, and promotion. This indicates a manufacturing-oriented technology supplier rather than a purely trading company.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, ISO14001, ISO50001, and other certifications. It also has a factory environmental impact assessment report, providing explicit evidence of quality, occupational safety, environmental, and energy-management certification coverage.

After-Sales capabilityThe supplier has documented corrective and preventive action procedures, complaint-handling procedures with follow-up records, written supplier-service assessment procedures, overseas agents or branches, and participation in the ENERGETAB trade show. However, the stated overseas-service-country count is 0, so the geographic scope of after-sales coverage is not fully clear.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and conducts technology development and related technical activities. Its stated close relationship with CEPRI further supports technical engagement, although no SDK is available.

Production capacityProduction-related evidence includes valid manufacturing contracts with associated subcontractors, inventory capability, uniform finished-product inspection instructions, a reported one-month lead time in both peak and off-season periods, and 50 qualified suppliers. No overseas warehouse or showroom is available, but those limitations do not negate the stated manufacturing capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, indicating broad product-development and customization support.

Client casesThe supplier reports providing OEM services to well-known brands and maintains a long-standing, close relationship with CEPRI. These statements provide customer-reference evidence, although no specific brand names, project details, or order outcomes are supplied.

Product Q&A

Q:What is the mechanical strength rating?

The U120B insulator has a bearing capacity of 120kN, ensuring high mechanical strength for power transmission applications.

Q:How does the stain-resistant feature work?

The glass is heat-treated so that overvoltage causes a puncture arc through the glass instead of a flashover, making the damaged unit visibly shattered while keeping the string intact.

Q:Is OEM and ODM service available?

Yes, we provide comprehensive customization options including OEM, ODM, sample customization, and flexible design modifications.

Q:What certifications does the product have?

The product is certified with CE and ISO9001 standards, and the company holds ISO45001, ISO14001, and ISO50001 management system certifications.

Q:What is the minimum order quantity?

The minimum order quantity is 100 pieces for this glass insulator product.
