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:
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.
International certification, such as EU CE and US UL certifications, which need to comply w...
