Electricity Transmission & Distribution

Protecting life and equipment within electricity transmission and distribution

Electricity is generated via a portfolio of new and traditional energy sources into Ultra High Voltage (UHV) and High Voltage (HV) electricity (AC or DC) to ensure efficient transmission with minimal energy loss.

Electrical substations then transform UHV and HV to Medium Voltage (MV) and Low Voltage (LV) which enables the electricity to be used in industrial and domestic applications. The OsecoElfab portfolio provides protection for applications throughout the transmission and distribution process.

Circuit Breakers

Special high-performance rupture discs are used to protect high voltage SF6 gas circuit breakers. The rupture disc design is normally customized for the breaker.

Gas-Insulated Switchgear

The gases used to insulate gas-insulated switchgear (GIS) systems are most effective when compressed. They are therefore kept under high pressure. Should the pressure drop, arcing can occur, leading to potentially devastating fires and explosions. OsecoElfab offers a full line of rupture discs to provide high-integrity pressure relief. Our unique designs feature superior leak-tightness with a wide choice of materials.


High voltage transformers often utilize a rupture disc to protect the tank on high voltage transformers.
