SERGI CONSERVATOR SHUTTER Type TL

Essential fire protection for transformer safety

FEATURES

Isolates quickly and effectively the oil in the Conservator tank.​

Can be installed on either new or existing transformers​

Is available in two different sized models to DN50 (2-inch) and DN80 (3-inch) conservator piping​

When transformers explode after short-circuits, the SERGI CONSERVATOR SHUTTER Type TL isolates the conservator when an abnormal flow is detected for preventing the conservator oil to feed the consecutive oil fire.​

The SERGI CONSERVATOR SHUTTER Type TL is a flow sensitive shutter valve:​

  • Rapid Isolation: Quickly and effectively isolates the oil in the conservator tank when abnormally high oil flow is detected. This can be caused by a ruptured transformer tank, an open valve, a significant pipe leak, or a damaged radiator.​
  • Bidirectional Flow: Allows oil to flow in both directions when transformers are in normal operation with oil temperature and volume variations due to transformer power or outside temperature changes.​

It is important for transformer safety and recommended by industry-leading organizations such as IEEE, CIGRE, etc.​

Characteristics of the SERGI CONSERVATOR SHUTTER Type TL:​

  • Market-Exclusive Testing: The only shutter on the market tested under transformer insulation rupture conditions. Live test certificates are available upon request.​
  • Self-Contained and Mechanical: Fully mechanical design requires no external power source.​
  • Commissioning-Free: Ready to operate immediately without any need for commissioning settings.
  • Easy Operation: Includes a testing lever for straightforward functionality.​
  • Integrated Alarm System: Equipped with a magnetic switch that sends an alarm to the plant control room when the TL closes.​

The SERGI CONSERVATOR SHUTTER Type TL use is frequently recommended on electric utilities in earthquake and hurricane-prone areas, where movement often leads to ruptured or leaking transformer conservator pipes.​
