HIGH VOLTAGE

Azarklid Electric Industries Co., in cooperation with IDEA 45 Italy, is a manufacturer and supplier of internal medium pressure switches and open air blades up to 36 kV level, as well as high pressure open air disconnectors up to 550 kV level. The result of more than 40 years of cooperation experience is the design and production of medium pressure and high pressure switches with the highest reliability factor with a wide voltage and current range for harsh and polluted environmental conditions and with high thermal efficiency. Sectionals are designed and manufactured according to IEC6227-1 and IEC62271-102 standards.
