Open Ventilated 3D Wound Core Dry-type Transformer

The SG(B) Series H-Class Open Ventilated Dry-Type Power Transformer is a three-phase non-encapsulated dry-type transformer manufactured with NOMEX® H-class insulation system. It features high safety, reliability, energy efficiency, fire resistance, explosion-proof performance, and simple maintenance. With advanced design, reasonable structure, and elegant appearance, its key performance indicators such as partial discharge level, no-load loss, load loss, noise level, and humidity resistance exceed relevant domestic and international standards. This transformer adopts an open ventilated structure, ensuring excellent heat dissipation and stable operation under heavy loads. The H-class insulation system allows safe operation at higher temperatures, significantly improving thermal endurance and service life. Designed to perform reliably in high-humidity, polluted, and high fire-risk environments, the SG(B) series can be installed near lakes, rivers, coastal areas, and other harsh environments. It is especially suitable for locations with high fire safety requirements and dense population.
