AI-Powered supplier vetting
SummaryDALIAN HIVOLT POWER SYSTEM CO., LTD. is identified as a China-based limited company in Dalian, with its entity type described as both a trading company and manufacturer/factory. Its stated product scope centers on electrical insulators and related components. The supplier reports ISO 9001 and ISO 14001 certifications, five production lines, 41–50 R&D engineers, and 41–50 quality-control staff. It states that products can be supplied to IEC, ANSI, BS, or customer specifications and offers replacement for quality-defective insulators within 12 months after receipt. Reported production includes glass, transformer bushing, composite, and station post insulators, with Shanghai listed as the shipment origin and a one-month off-peak lead time. Trade records show transactions involving VANGUARD ELECTRIC LLC and INTERNATIONAL ELECTRICAL SALES CORP.; however, the available records are limited and do not establish broad customer depth or long-term performance.
Supplier typeThe supplier is described as a trading company in the company classification and as both a trading company and manufacturer/factory in the entity-type record. This supports a mixed trading and manufacturing business profile, although the slices do not independently verify the extent of its own manufacturing operations.
CertificationsThe supplier reports ISO 9001 and ISO 14001 management-system certifications. It also states that manufacturing follows ISO 9001:2008 processes and that products can meet IEC, ANSI, BS, or customer specifications, providing explicit evidence of certification and standards-oriented quality controls.
After-Sales capabilityThe supplier explicitly promises to replace insulators with quality defects at no charge within 12 months after receipt. This is direct evidence of a defined after-sales remedy, though the slices do not describe response times, service locations, or claim procedures.
R&D capabilityThe supplier reports 41–50 R&D engineers and describes powerful testing facilities and ongoing product-quality improvement. These statements support the existence of R&D and testing resources, but no specific new product, patent, or innovation achievement is provided.
Production capacityThe supplier reports five production lines and stated annual outputs of 100,000 glass insulators, 1,000,000 transformer bushings, 500,000 composite insulators, and 50,000 station post insulators. It also reports a one-month off-peak lead time, providing explicit evidence of established production capacity and delivery planning.
Customization capabilityThe product scope includes multiple insulator types, including porcelain, composite, glass, transformer bushing, station post, hollow, silicone rubber, polymer, and pin-type insulators. The supplier explicitly states that it can supply products to IEC, ANSI, BS, or customer specifications, supporting customization capability.
Client casesTrade records associate the supplier with VANGUARD ELECTRIC LLC for polymer post-type insulators and with INTERNATIONAL ELECTRICAL SALES CORP. for an electrical connector item. These records provide identifiable customer and shipment examples, but the limited number of documented transactions does not demonstrate a broad or extensive customer portfolio.
