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.

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.
