‌The National and Group Standards for Wind Turbine Seals and Smart PV Tracking Systems, in which Jingwei participated in drafting, have been officially released.

‌

Recently, the National Standardization Administration and relevant industry organizations officially released the ‌National Standard GB/T 33154-2025 "Rubber Seals for Yaw Bearings and Pitch Bearings of Wind Turbines"‌ and the ‌Group Standard T/CI 1083-2025 "Smart Tracking PV Mounting Systems."‌ MAANSHAN JINGWEI NEW ENERGY DRIVE EQUIPMENT Co., LTD . and its subsidiary MAANSHAN JINGWEI NEW ENERGY DRIVE EQUIPMENT Co., LTD served as key drafting units, deeply involved in the technical review and drafting of both standards, marking another recognition of the company's technical strength in wind turbine sealing and PV tracking systems.

The two standards focus on key components and technological systems in the new energy industry, aiming to further improve the technical specification system for wind and PV sectors and provide crucial technical support for achieving the "dual carbon" goals.

‌GB/T 33154-2025‌ systematically regulates the performance requirements of rubber seals for yaw and pitch bearings throughout their lifecycle. The new standard introduces specifications for multi-lip seal structural design, establishes a precise dimensional tolerance system, and sets stricter finished product performance indicators, meeting the sealing reliability demands of wind farms in extreme environments such as high/low temperatures, strong UV exposure, and high salt spray.

‌T/CI 1083-2025‌ focuses on the intelligent upgrade of PV tracking systems, clarifying key performance parameters such as tracking accuracy, wind resistance, and seismic resistance, promoting the expansion of mounting systems from flat terrains to complex scenarios like mountainous and water surfaces, and providing an important technical basis for improving the overall power generation efficiency and system reliability of PV power plants.

As an enterprise in the wind and PV new energy sector, Jingwei has long been deeply engaged in R&D for critical technologies in sealing systems and new energy equipment, continuously increasing R&D investment, and building a full-chain technical system covering material formulation, structural design, and performance testing.

During the drafting of ‌GB/T 33154-2025‌, Jingwei actively contributed its engineering experience in sealing structure and material performance, collaboratively promoting the implementation of related technologies. In ‌T/CI 1083-2025‌, it assisted in demonstrating technical parameters for the adaptation between tracking systems and seals, effectively driving the transformation of corporate innovation achievements into industry-wide norms.

In the future, Jingwei will leverage the release of these two standards to continue deepening R&D investment, promoting the coordinated improvement of technological innovation and standardization in the new energy sector, and contributing to the high-quality development of the modern new energy industry.
