Hermetically Sealed Transformer Manufacturers
Hermetically sealed transformers are protective device-free, enclosing the insulating medium to prevent air infiltration, avoiding corrosion and sedimentation. Sealed oil transformers use closed water tanks to accommodate temperature changes. They ensure stable electrical characteristics, requiring minimal maintenance, ideal for harsh environments. Synthetic coolant encapsulated transformers are suitable for indoor use, offering environmental benefits. Equipped with nitrogen-filled air cushions, they regulate temperature-induced volume changes, ensuring durability and performance.
- The rated power is between 50KVA and 2500 KV
- The voltage level is between 1.1 KV and 33 KV
- Temperature of materials belonging to “A” category
- The design ambient temperature is 500 C
- The winding material in transformers can either be aluminum or copper.
- These transformers are sealed using oils such as ester oil, mineral oil, or silicone oil.
- The sealed transformers are equipped with pressure control valves, thermometers, liquid level indicators, anti-vibration devices, and protective enclosures.
- They are designed for outdoor installation, even in challenging environments, and are compact in size, making them suitable for high-voltage applications.
- One of the significant advantages of sealed transformers is their exceptional resistance to resonance overvoltage.
