AI-Powered supplier vetting

SummaryRadin Electric Technology Co., Ltd. is identified as both a trading company and manufacturer/factory in China, focused on low-voltage distribution, protection, and electrical control products. The supplier reports more than 10 production lines, 50 years of total R&D engineer experience, 41–50 quality-control staff, and annual automatic transfer switch output of 200,000 units. It holds ISO 9001 certification and describes quality controls covering design, manufacturing, storage, transportation, and technical service. The supplier also reports technical support from pre-sale through after-sales service, service stations and agents, and exports to multiple global regions. Evidence supports production scale, quality-system certification, and service capability. However, the provided information does not establish financial credibility, customer-specific cases, or a defined customization program.

Supplier typeThe supplier is described as both a trading company and a manufacturer/factory, with a stated focus on producing low-voltage distribution and protection products. Its legal and operational descriptions identify it as a China-based electrical manufacturing enterprise, although one slice also classifies the company nature as a trading company.

CertificationsThe supplier explicitly reports certification of its management systems under ISO 9001. This provides direct evidence of a documented quality-management certification, though no other certifications are stated.

After-Sales capabilityThe supplier states that it has a professional technical support and service team covering pre-sale through after-sales service, and that it is building working agents and service stations to provide local support. These claims directly indicate an organized support structure, although service performance metrics are not provided.

R&D capabilityThe supplier reports 50 years of total R&D engineer experience and describes the successful launch of RDQ dual-power automatic transfer switches and RDW intelligent air circuit breakers. It also states that it applies advanced technology to electrical products, providing direct but limited evidence of product-development capability.

Production capacityThe supplier reports more than 10 production lines, 41–50 quality-control staff, and annual production of 200,000 automatic transfer switches. Its manufacturer/factory classification and stated focus on production further support operational capability, although capacity for products other than automatic transfer switches is not quantified.
