Air-break isolators and disconnect switches engineered for dependable isolation across the 11 kV–245 kV range — for substations, distribution networks and industrial switchyards.
An isolator only matters when it works every time. ENSOL manufactures air-break isolators with robust contact systems, smooth operating mechanisms and corrosion-resistant hardware, built to maintain isolation distances and switch reliably for years. Available in single and double break, with manual or motorised operation, across distribution and transmission voltage classes.
Double-break and centre-break isolators for outdoor substations across voltage classes.
Reliable disconnection for maintenance isolation and network reconfiguration.
Distribution-class air-break switches for the 11 kV–33 kV network.
Isolators with integrated earthing for safe maintenance.
Hand-operated or motor-operated mechanisms to suit the application.
Distribution protection hardware available alongside isolators.
