Overview

The 27kV pole-mounted three-phase recloser, specifically designed for overhead power grid protection, not only integrates overload/short-circuit protection and automatic reclosing functions but also is compatible with remote monitoring systems, effectively enhancing the reliability and automation level of the distribution network.The U-Series 3 phase pole mounted auto recloser (or circuit breaker) uses the latest technology in solid dielectric epoxies, vacuum interruption, and other materials. This device does not use any gas or oil insulation. Instead, cyclo-aliphatic epoxy bushings are used to insulate the vacuum interrupters. This type of construction results in a more lightweight unit. The design has been optimized for automation, remote control, and monitoring applications and has built in current and voltage measurement for data logging.
