1972 - Development of the First Domestic Low Oil Cutter
The first examples of the indigenous low-fat breaker were produced in the high-voltage fuse production workshop of the Turkish Electricity Authority's regional directorate in Adapazarı, by Tevfik Mağara and his maintenance and repair team. Many of these breakers were used in the plant for many years.
1977 - Start of Low Oil Cutter Manufacturing in Izmir
Low oil cutter poles and mechanisms were produced in technical cooperation with Electroputere - Romania. Electrical cabling, winding motor, on/off coils and other equipment were manufactured locally. The initial workshop was 300 m² in İzmir 2nd Industrial Site and the capacity was increased to 600 m² in a short time. By the end of 1978, the mechanisms were completely produced domestically.
1977 - Start of Medium Voltage Parafuse Production
In cooperation with MINEL - Yugoslavia, production started by importing silicon carbide variable resistors, porcelain insulators and other parts were supplied locally. The first investment was 200 kV lightning impulse voltage test equipment.
1980 - First Silicon Carbide Variable Resistor Manufacturing for Medium Voltage Surge Arrester
MINEL - Production started at the factory in Kemalpaşa with technology purchased from Yugoslavia.
1980 - Domestic Insulation Production in Epoxy Resin Plant
The production of glass fiber epoxy insulated pole tubes was started and the production of low oil cutters was completely domesticized.
1984 - First Domestic Medium Voltage SF6 Gas Breaker Production
NMG - SF6 gas interrupters were produced locally with technology purchased from Italy. Insulated poles were manufactured in epoxy resin plant.
1985 - 72.5-170 kV High Voltage SF6 Gas Breaker Production
In cooperation with Energoinvest - Yugoslavia, SF6 gas insulated poles were imported and other parts were produced locally. 350 kV high voltage and 900 kV lightning impulse devices were used in the tests.
1985 - 72.5-170 kV High Voltage Surge Arrester Production
Cooperation with Siemens - Germany, import of silicon carbide variable resistor and production started with locally produced parts.
1985 - 72.5-170 kV High Voltage Center Disconnector and Pantograph Type Disconnector Production
Designed and produced entirely locally by R&D engineers.
1985 - 380 kV High Voltage Surge Arrester Production
Produced in cooperation with Siemens - Germany; some parts are imported, other parts are locally produced.
1985 - Production of External Type SF6 Air Arc Extinguished Automatic Load Separator
Designed and produced entirely locally by R&D engineers.
1986 - First Domestic Vacuum Cutter Production
FUJI - Vacuum shear cells were imported from Japan and manufactured by purchasing isolated pole bearings and mechanism technology.
1986 - Medium Voltage Jumping Intermittent Metal Oxide Variable Resistance Surge Arrester Production
In cooperation with Hitachi - Japan, metal oxide variable resistors were imported and other parts were produced domestically.
1991 - Establishment of Batel Elektromekanik
Founded to contribute to Turkey's energy infrastructure. It entered the sector with domestic production and innovative engineering approach.
1991 - BATEL 36kV 630A 16kA and 36kV 1250A 25kA SF6 Gas Breaker Pole Production
One of the important steps of domestic production capacity was realized.
