Disconnectors

In a power network, a disconnector is used to ensure that an electrical equipment is completely de-energized and isolated for service or maintenance. Hitachi Energy offers a wide range of reliable and energy efficient disconnectors ranging from 72.5 kV to 800 kV. 

Maximum reliability and minimal maintenance

Hitachi Energy offers a wide range of reliable and energy efficient disconnectors to meet the requirements of different sites and network conditions. The disconnectors range from 72.5 kV to 550 kV.  Our disconnectors are designed as per IEC 62271-102 and IEC 62271-1 standards. Also, other standards and regulations (eg, IEEE, GOST, and GB) can be met on request. Accredited testing laboratories carry out type tests on the disconnectors in accordance with the latest regulations. The world-class quality of disconnectors is ensured through comprehensive electrical and mechanical routine tests on the poles and operating mechanism of each disconnector.
