33kV HT Panel

A 33kV HT Panel is a high tension medium voltage switchgear assembly used for receiving, switching, controlling, and protecting electrical power at 33kV distribution level. The Schneider Electric EvoPact HVX-O is a vacuum circuit breaker designed for air-insulated switchgear up to 36kV, available in fixed, withdrawable, and integrated protection system configurations. The EvoPact HVX operating mechanism gives the device an opening and closing speed that is independent of the operator whether the command is electrical or manual, and ensures that the open order always takes priority over the close order. It is widely used in primary distribution substations, heavy industries, renewable energy grid connections, and large infrastructure projects where reliable 33kV switching and fault protection is critical.
