We supply the full range of switching and protection equipment for medium and high-voltage transmission and distribution applications across all voltage levels.
Click on any product below to view the full range of specifications, configurations, and equipment examples we can source for your project.
We source circuit breakers from 145 kV to 765 kV, covering the full transmission voltage range. Available in SF6, vacuum, and air-insulated technologies — including outdoor live-tank, dead-tank, and GIS-integrated configurations. Whether you need a single unit or a complete substation supply, we identify the right solution from our qualified manufacturer network.
Load-break and fault-interrupting circuit switchers for substation and feeder applications. Cost-effective alternatives to full circuit breakers where fault current levels allow, available for outdoor overhead and pad-mounted installations across medium and high-voltage systems.
Gang-operated and single-pole disconnectors for safe isolation of equipment during maintenance. Available in vertical, horizontal, and pantograph designs for outdoor AIS and gas-insulated substation applications, from medium voltage through ultra-high voltage.
Fast-acting and maintenance grounding switches for safe grounding of de-energized lines and equipment. Available with make-proof capability for operation on systems with live or induced voltage, ensuring personnel safety during substation and line maintenance.
Single-phase and three-phase automatic circuit reclosers for overhead distribution lines. Programmable automatic reclose sequences reduce outage duration and improve system reliability on medium-voltage distribution networks, with integrated protection and control electronics.
Current-limiting and expulsion fuses for transformer, capacitor bank, and feeder protection across medium-voltage systems. Available in indoor and outdoor configurations for a wide range of interrupting ratings and voltage classes.
Metal oxide surge arresters for overvoltage protection of transformers, cables, and rotating machines. Available in station, intermediate, and distribution classes for installations across the full range of system voltages, with polymer and porcelain housing options.

In medium voltage and high voltage systems, switching and protection equipment performs the functions that keep the network safe and stable.
Detects electrical faults — short circuit, overload and earth fault
Isolates damaged sections of the network
Maintains system stability and continuity of supply
Protects transformers, cables and switchgear
Reduced equipment failure risk
Prevention of widespread power outages
Improved overall system reliability
Extended equipment service life
Properly specified switching and protection systems directly improve grid performance.
