Pole-mounted switchgear equipment is used for switching, fault management and line sectionalizing on medium-voltage overhead lines. The function of each device is determined according to the network configuration and protection coordination requirements.

Automatic circuit reclosers interrupt fault currents within their rated capacity and reclose according to a predefined operating sequence. Load-break switches perform specified load-switching duties. Automatic line sectionalizers operate in coordination with a suitable upstream protection device to help isolate the faulty section of the line. These functions vary depending on the selected product.

Controller options may include metering, event recording, protection, remote control and SCADA communication. Voltage and current ratings, short-circuit capabilities, insulation levels and outdoor performance requirements are determined on a product-specific basis. Reclosing and automatic restoration scenarios are designed according to the network’s operating rules.
