Sectionalizers

Automated devices that isolate faulted sections to improve power system reliability.

Home / Sectionalizers

Overview

For a long time there had been a strong need in the market for low cost and effective sectionalizing, especially for semi-urban and rural feeders. Long overhead lines with too many branches and limited load, it becomes commercially unviable to install expensive solutions. Sharika’s SmartOn™ SLBS is the right solution for 11 to 36 KV networks with multiple options of control. With strong and efficient mechanical construction with comprehensive suite of automation levels, SLBS can fit every budget. Technical collaboration with S. Korea and matchless build quality with ease of operation & maintenance, SLBS can effectively bring down SAIFI & SAIDI, giving satisfied consumers and recover unserved revenue
