Overhead Line Project in Indonesia

Project overview

This outdoor utility project focused on improving feeder reliability across medium-voltage overhead distribution lines. The installation environment required equipment suitable for continuous outdoor service, clear fault isolation and dependable reclosing performance.

Customer challenge

Long feeder routes and outdoor exposure increase the risk of temporary faults, delayed isolation and extended outage windows. The project needed a practical combination of switching, protection and overvoltage devices that could be coordinated on pole-mounted networks.

Solution applied

• Pole-mounted reclosers for automated fault interruption and service restoration
• Sectionalizers to isolate faulted sections and keep healthy feeders energised
• Surge arresters for lightning and switching overvoltage protection

Project outcome

The package supports feeder protection, selective isolation and more stable outdoor power supply for utility networks operating under demanding field conditions.
