Product Overview
This S11-20(10)kV dual voltage oil immersed transformer is an upgraded version of the classic S9 series. Its biggest feature is that it can flexibly switch voltage (10kV or 20kV). This is particularly suitable for the needs of power grid upgrades. It can withstand more short-circuit current than the old S9 (capacity increased by 30%) and has lower noise during operation (reduced by about 5 decibels). It also adopts a fully sealed design that does not leak oil and is extremely energy-saving (20% energy-saving than S9).
Type And Meaning
Product Features
Pressure Relief Valve
Our oil-immersed transformers are equipped with a pressure relief valve. Once the internal pressure is too high (such as in the event of a fault), it will quickly open and release the pressure to prevent
Signal Thermometer
We also have a signal thermometer installed to monitor the transformer oil temperature in real time. Once the oil temperature exceeds the safe range, it will immediately alarm and remind personnel to handle it.
Buchholz Relay
We also have a Buchholz relay to monitor the fault gas generated inside the transformer. Once the gas is detected, it will immediately send out a signal to prompt the staff to inspect and repair.
