Guangdong Xinyuan Hengye Power Transmission Device Co.,Ltd. Quality Control

Power fittings are core components of transmission lines, and their quality directly affects the safe and stable operation of power grids. Quality certification serves as a core benchmark for measuring quality and ensuring project safety, and is also a key prerequisite for enterprises' industry access, market trust, and international layout.

The current quality certification system for power fittings includes three core categories:

1. Domestic certification, based on industry standards issued by the National Energy Administration (such as DL/T series), requiring full-item performance testing by authoritative third-party institutions; UHV fittings must meet additional special and stringent requirements.
2. International certification, such as EU CE and US UL certifications, which need to comply with local technical, environmental and safety standards, and are essential for expanding international markets.

The certification process mainly includes four closed-loop links:

1. application,
2. type test,
3. factory inspection, and
4. post-certification supervision, ensuring product quality stability throughout the entire chain.

As a pioneer in supplying UHV fittings, Xinyuan Hengye's products have fully passed domestic industry standard certifications and third-party testing, and have also obtained multiple international certifications, adapting to the needs of power transmission projects in many countries. The company also participates in the formulation of multiple standards and has established a full-process quality traceability system to ensure that every product meets certification standards, providing solid protection for the safe operation of over 1,000 power transmission and transformation projects worldwide.
