Hermetically Sealed Transformers: Ultimate Protection for Reliable Power
Introduction
In environments where reliability and protection are paramount, Hermetically Sealed Transformers provide a superior solution. Designed to prevent moisture, dust, and contaminants from entering the transformer, these units ensure long-lasting, maintenance-free operation. Ideal for harsh climates and sensitive installations, they guarantee uninterrupted power supply with enhanced durability.
What is a Hermetically Sealed Transformer?
A Hermetically Sealed Transformer is an oil-immersed transformer completely sealed from the external atmosphere. Its tank is welded airtight, preventing any ingress of moisture, oxygen, orAs the transformer heats up during operation, the oil expands and contracts within the contaminants, which could degrade insulation and oil quality. This design eliminates the need for conservator tanks and reduces maintenance.
How Does It Work?
The transformer’s core and windings are immersed in insulating oil inside a sealed tank.
A flexible diaphragm or bladder inside the tank accommodates this oil expansion without allowing air to enter.
The airtight seal preserves the oil’s insulating properties and protects the internal components from external contaminants.
Purposes
To protect transformer oil and insulation from moisture and oxidation
