AI-Powered supplier vetting

SummaryYONGU GROUP CORPORATION CO., LTD. is a China-based limited company operating in electrical and electronics, with a stated establishment date of 1999 and manufacturing operations in Zhejiang. The supplier reports substantial industry experience, export activity since 2005, 507 employees in one record, and a 35,000 m² manufacturing plant. Its product range covers power fittings, clamps, cable accessories, insulators, switches, breakers, fuses, arresters, and related products. Evidence supports ISO 9001 and ISO 14001 certification, dedicated research and testing facilities, production licensing, and product testing by several Chinese power-industry institutions. The supplied information does not sufficiently establish after-sales execution, financial credibility, customization capability, or identifiable customer cases. Some company-scale data is inconsistent across records, including employee count, establishment history, and facility size, so those details should be verified.

Supplier typeThe supplier is identified as a combined, limited company headquartered in Zhejiang, China, engaged in electrical and electronics and offering a broad portfolio of power fittings, cable accessories, switching equipment, and protection products. It also reports export activity and accepts FOB, CIF, and CFR quotation terms, indicating capability to engage in international trade.

CertificationsThe supplier reports ISO 9001:2015 and ISO 14001:2015 certificates, earlier references to ISO 9001 and ISO 14000, production licenses, and product testing by recognized Chinese electric-power inspection and research institutions. These records provide explicit evidence of quality and environmental management certifications and product compliance-related credentials.

R&D capabilityThe supplier reports a dedicated technical research and development center recognized as a provincial township business technical service center and enterprise technical center, together with machinery, physics, chemistry, pressure, partial-discharge, and heat-cycle testing facilities. This directly supports established R&D and technical testing capability.

Production capacityEvidence includes a stated 35,000 m² manufacturing plant, production licenses, advanced laboratory equipment, a broad product portfolio, and testing of electric anchor clamps and related products by multiple power-industry institutions. The records support meaningful manufacturing capability, although company-scale figures differ across slices and should be verified.

Product Q&A

Q:What are the available connection types?

The arresters feature either a piercing electrode that penetrates insulation or a non-piercing clamp method that preserves insulation.

Q:How does the internal gap work?

The internal gap breaks down under lightning overvoltage to discharge surge current through the MOV, while isolating the MOV from system voltage during normal operation.

Q:What voltage levels are supported?

These devices are specifically engineered for lightning protection on 10-35kV overhead distribution lines with insulated conductors.

Q:Does the piercing type damage the cable?

No, the piercing type features a sharp electrode that penetrates insulation to make direct contact without stripping the cable.

Q:What is the lead time for orders?

Peak season lead time is one month, while off-season lead time is within 15 workdays.
