AI-Powered supplier vetting

SummaryBushing (Beijing) presents itself as an equipment and electronic-product supplier focused on high-end intelligent bushing applications. It holds ISO9001:2015 and ISO14001:2015 certificates, reports documented service, corrective-action, and complaint-handling procedures, and offers OEM, ODM, SDK, and broad customization services. Production evidence includes two production lines, stated HV bushing output of 10,000 pieces, 14 quality assurance and control inspectors, and finished-product inspection instructions. However, the supplier reports no valid manufacturing contract with related subcontractors, no standardized outsourcing procedure, and no ongoing batch quantity reconciliation. It has inventory capability and an overseas showroom but no overseas warehouse. The information indicates innovation, customization, quality-system, and production capabilities, while customer cases and financial credibility remain insufficiently evidenced.

Supplier typeThe supplier operates in equipment manufacturing and related electronic-product, instrument, software, and technical-service activities. Its stated focus on intelligent bushing products, together with reported OEM and ODM services, supports classification as a manufacturer with integrated technical and customization capabilities.

CertificationsThe supplier explicitly reports ISO9001:2015 and ISO14001:2015 certificates, indicating stated certification in quality and environmental management systems.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaints. It also reports inventory capability, an overseas showroom, and defined quotation and payment options, but lacks an overseas warehouse; the documented procedures nevertheless provide explicit evidence of service capability.

R&D capabilityThe supplier reports new products during the past year, ODM service, available SDK support, and technology development, consulting, exchange, and transfer activities. These statements provide explicit evidence of active R&D and technical innovation capability.

Production capacityProduction evidence includes two production lines, stated HV bushing output of 10,000 pieces, 14 quality assurance and control inspectors, finished-product inspection instructions, and inventory capability. However, the supplier reports no valid manufacturing contract with related subcontractors, no outsourcing SOP, and no continuous batch quantity reconciliation, which are material production-control weaknesses.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization. The same capability is reported in both R&D and design-service information, supporting a broad customization offering.

Product Q&A

Q:What makes this oil tank ideal for transformers and power equipment?

Sealed design prevents oil contamination from air, dust, or moisture, ensuring long-term stability. Corrugated stainless steel construction expands/contracts with oil volume changes, eliminating mechanical jamming and extending service life beyond 30 years. Full sealing reduces labor costs by eliminating frequent oil changes or vacuum filtration.

Q:How does the corrugated structure improve performance?

Volume compensation automatically adjusts to oil expansion/contraction during temperature fluctuations. Pressure resistance maintains internal oil resistance against metal cores under extreme operating conditions (<0.005MPa). Maintenance-free design requires no manual adjustments, reducing downtime and operational costs.

Q:What industries or equipment use this oil tank?

Power grids: Large/medium transformers (110kV-1000kV). Industrial plants: High-voltage switchgear, circuit breakers. Renewable energy: Wind turbine transformers, solar inverters.

Q:How is the oil level monitored?

Mechanical oil level gauge provides an intuitive, contact-type indicator with high/low alarm signals (DA/AC, 220V 0.3A). Accurate measurement connects to the external atmosphere via a desiccant vent to prevent false readings.

Q:What certifications or standards does it meet?

IEC 60137 compliance for transformer bushings and reservoirs. GB/T 14598 Chinese national standard for electrical equipment reliability. IP65 rating for dust/water resistance for outdoor installations.
