We supply tap changers, oil level indicators, moisture holders, bushings, pressure protection valves, protection relays, thermometers and thermometer pockets, valves and flanges, wheels, fans.
Tap changers are devices used to change the turns ratio by switching between the outputs provided at various points of the winding. Produced in 5, 6 or 7 stages, tap changers are available in models that change under load or with a thimble.
Maintaining the oil level in transformers is vital for transformer life. With oil level indicators, the oil level in transformers can be reliably controlled and measured. Oil level indicators are produced in different specifications as horizontal and vertical type.
The insulating oil used in transformers must be isolated from atmospheric air and therefore from moisture. Since moisture will affect the insulation level of the transformer, moisture traps are installed in the transformer boiler and provide moisture isolatio
Transformer bushings (insulators) are components that form the insulation system of the transformer and enable the connection of the output and input lines to the transformer body. Insulators are produced in the range of 1.2 kV 250 A-5000 A, 52 kV 250 A-8000 A.
It is necessary to maintain the pressure of the oil inside the transformers that provides insulation. In case of failure, the pressure inside the transformer is opened. The pressure protection valve opens when the pressure increases and ensures that the pressure level is reduced to the desired value.
In hermetic type transformers, transformer oil does not come into contact with air and thus has a longer service life. Transformer Protection Relay can measure the oil temperature, show the oil level and gas accumulation, and when it exceeds a certain limit, it cuts the circuit by detecting the internal pressure.
In transformers, temperature is a critical parameter for the safe and efficient operation of the transformer. The temperature of the transformer protection oil is monitored instantaneously by means of thermometers. Thermometers are mounted on the transformer with a thermometer pocket made of metal.
In oil type transformers, valves and flanges are the components that serve the oil system and connection points of the transformer. Butterfly valves, flanges and NV22 type oil drain valves used in oil type transformers are manufactured in DIN standards.
Wheels increase the transportability, ease of placement, maintenance accessibility and mobility of transformers. This enables transformers to be used and operated more flexibly. Transformer wheels made of metal are optional on transformers.
In order for the transformers to operate long-lasting and efficiently, the internal temperature of the transformer must be kept at a constant value. In "air forced", i.e. forced air cooled transformers, air is directed through ventilation fans on the radiators.
