Compliance with standards such as IEC 61439-1 and GB 7251.1 is required to ensure the specified degree of protection (e.g., IP54 dust and water resistance) and temperature rise limits (typically ≤40K).
There is currently no single, unified national standard specifically for air-cooling control cabinets; in practice, compliance is primarily based on the core industry standard *JB/T 10780-2024: Technical Conditions for Air Coolers and Control Cabinets for Transformers*, alongside various fundamental national standards.
The latest standard widely recognized within the industry is *JB/T 10780-2024: Technical Conditions for Air Coolers and Control Cabinets for Transformers*. It specifies that next-generation products must meet performance requirements such as an IP55 protection rating, dual-circuit redundant power supply, and precise multi-parameter coordinated control based on oil and winding temperatures.
