Three-phase dry power transformers with geofole cast insulation with voltage up to 10.5 kV are designed to convert electricity in the networks of power systems and consumers of alternating current electricity of a nominal frequency of 50 Hz.

Transformers are equipped with Siemens windings, the windings are aluminum.


Three-phase dry power transformers with geofole cast insulation with voltage up to 10.5 kV are designed to convert electricity in the networks of power systems and consumers of alternating current electricity of a nominal frequency of 50 Hz.

Transformers are equipped with Siemens windings, the windings are aluminum.

To isolate the windings, an epoxy compound with quartz filler (geafol) is used.  Additionally, the windings are reinforced with fiberglass, which eliminates the occurrence of cracks in the epoxy compound even when transformers are overloaded.  Geafol does not have a harmful effect on the environment, does not emit toxic gases even when exposed to arc discharges.  Thanks to this insulation, the windings are maintenance free.

To measure and control the temperature, the transformers are equipped with a TR-100 digital temperature relay with three PT100 temperature sensors built into the LV windings.  For special transformers (for powering semiconductor converters, etc.), as well as at the request of the customer, an additional sensor is installed to control the temperature of the magnetic circuit.

The TP-100 temperature relay equipped with the RS-485 MODBUS RTU interface is connected to direct or alternating voltage from 24 to 260 V.

In case of a dangerous increase in temperature, the output control relay of the alarm circuits is triggered.  If the temperature increase continues and the temperature exceeds the maximum permissible value, the output relay control alarm (emergency shutdown of the transformer) is activated.

At the request of the customer, other types of devices for temperature control can be installed.

Transformers TSGL, TSDGL (without a protective cover) is equipped with temperature sensors with a cable length of ten meters, which allows you to transfer the thermal protection relay or fan control box for TSDGL to the building envelope or other structural elements of the substation (up to six meters) to ensure its safe and  convenient service.  At the request of the customer, other types of thermal protection can be installed.

Transformers TSDGL, TSDZGL, TSDZGLF, TSDZGL11, TSDZGLF11 are equipped with a forced cooling system consisting of a control box and winding cooling fans.  The use of forced ventilation allows to increase the capacity of dry transformers up to 40%.
