Protection Devices
Bimetal thermometers are designed to monitor the temperature of the oil in the boiler in hermetic or expansion tank transformers. The thermometer is equipped with a two-contact switch (with or without) and a sweep pointer. The Bimetal Thermometer should be used with the thermometer pocket welded to the top cover of the distribution transformer.
Moisture Holders
Moisture Holders are used to remove moisture from the air entering the tank of transformers with oil-cooled expansion tanks. In this way, it prevents water condensation in the expansion tank and increases the operating safety of the transformer.
- Moisture Holder type L Form E (DIN 42562 / EN 50216-5)
- Moisture Hodler Form A / B / C (DIN 42567 / EN 50216-5)
Oil Level Indicators
Our oil level indicators are used in oil type distribution and power transformers with hermetic and expansion tanks.
- Magnetic oil level indicators Din 42569 Form A,B,D,E
- Vertical oil level indicators (Oli-D)
- Vertical magnetic oil level indicators (Oli-E)
- Oil level indicators with ball hermetically (Oli-C)
Pressure Relief Device Valves
Pressure relief device valves are used for the purpose of evacuating the high pressure formed inside the hermetic oil type transformers from inside the transformer tank.
- Pressure Relief device Valve – G1″
- Pressure Relief device Valve Long spring- G1″
- Pressure Relief device Valve – G1 ½”
- Pressure Relief device Valve – G2″
- Pressure Relief device Valve (with relief valve) – G2″
Transformer Radiator Valves
Transformer Radiator valves with steel body are produced according to Din 42560 norm. It is positioned between the radiator and the boiler by welding or mounting on the boiler wall of oil-type power and distribution transformers. It provides the passage of the insulating liquid circulating in the boiler and radiators of the transformers.
