JB/T 5347-2026 Takes Effect: TengQi Technology Helps Advance Transformer Radiator Quality Through Standards Development
Industry Standard Update
Advancing Transformer Radiator Manufacturing Through Shared Standards
On September 1, 2026, JB/T 5347-2026, the updated standard for plate radiators used in transformers, officially came into effect. It replaces JB/T 5347-2013 and provides a renewed technical framework for the oil-immersed transformer radiator industry.
At a glance: Jiangsu Tengqi Electric Power Technology Co., Ltd., operating under the TengQi Technology (TQT) brand, participated as a main drafting organization in the revision of JB/T 5347-2026. The standard addresses key areas including service conditions, classification, specifications, product designation, construction, principal materials, technical requirements and test methods for transformer plate radiators.
A New Reference Point for Transformer Plate Radiators
Over more than a decade, transformer cooling requirements, manufacturing practices and application expectations have continued to evolve. The transition from the 2013 edition to JB/T 5347-2026 reflects the industry's ongoing effort to keep technical guidance aligned with current development needs.
For manufacturers, project partners and users of oil-immersed transformer equipment, a well-defined industry standard creates a clearer common reference for radiator product development, manufacturing and quality-related evaluation. It supports more consistent communication throughout the supply chain while encouraging continued improvement across the sector.
What the Updated Standard Covers
JB/T 5347-2026 further refines the standard framework for plate radiators serving oil-immersed transformers. Its scope includes the following important subject areas:
A clearer basis for relevant operating-use considerations.
A structured approach to product categories and specifications.
Updated reference points for identification and construction.
Guidance supporting product manufacturing and quality development.
An improved reference framework for relevant verification activities.
