Electricity Transmission & Distribution

Protecting life and equipment within electricity transmission and distribution

Our rupture discs for switchgear applications offer corrosion-resistant,low maintenance solutions that protect people and equipment from damage.

Should a pressure spike occur due to an electrical fault, the discs activate in milliseconds to provide quick, safe discharge of gases. The non-fragmenting designs increase protection for personnel, while tight tolerances and high operating ratios offer reliably breaking parameters.

Supporting the transition to net zero energy with innovative rupture disc solutions and service

We are experienced in working with the different pressures, sizes and disc profiles needed for switchgear units using clean air and other SF6 alternatives. Leak-tight designs reduce gas emissions and provide greater environmental protection.

 Our flexible R&D program allows us to quickly develop new designs and new technologies in partnership with you. Our innovative designs and manufacturing processes mean we can choose the best materials for your application, enabling you to stay ahead of changing demands in the power industry.

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.
