As chaves seccionadoras sob carga Omni-Rupter promovem a interrupção de longa vida e alto desempenho do circuito sem arco externo, e são ideais para as seguintes funções de seccionamento:

  • Seccionamento de linha, incluindo divisão e seccionamento de alimentadores
  • Seccionamento de transformadores
  • Seccionamento de cabos

As chaves seccionadoras sob carga Omni-Rupter estão classificadas para 900 ampères de corrente contínua e de interrupção em tensões nominais de 14,4 kV e 25 kV, e classificadas para 630 ampères de corrente contínua e de interrupção em 34,5 kV. Essas chaves seccionadoras operadas em grupo estão disponíveis em uma série de configurações de montagem para atender à grande variedade de configurações de linha encontradas nos modernos sistemas de distribuição.

Every year the grid becomes more dynamic and complex. Utilities are now contending with multiple distributed energy resources (DERs) throughout the distribution system, creating new challenges around maintaining reliability.

These technologies create two-way power flow, which is straining existing infrastructure. To manage DERs, utilities are increasing grid sectionalization. But that’s creating its own challenges.

Achieving widespread sectionalization requires your overhead feeder switches to be dependableregardless of whether you deploy 10 or 1,000 switches. Ineffective switches can worsen customer outages, hurt your reliability performance metrics, and add operations and maintenance (O&M) costs to your balance sheet.

S&C’s Omni-Rupter® Switches are key for mass sectionalization because they’re dependable, robust, and hassle-free to install.
