Pole Top Vacuum Switch

Pole Top Vacuum Switch for Flexible Load Switching and Overhead Line Sectionalizing

Designed for modern medium-voltage distribution systems, the Pole Top Vacuum Switch provides a reliable and economical solution for overhead line switching, feeder sectionalizing, and network reconfiguration. Unlike a protection circuit breaker, this switch is primarily intended for load switching and network isolation, allowing utilities to improve operational flexibility while reducing maintenance costs. Its compact structure, maintenance-free vacuum interrupter, and excellent environmental resistance make it an ideal choice for overhead distribution networks, renewable energy projects, industrial power systems, and rural electrification.

Our product portfolio also includes the 12KV Pole Mounted Circuit Breaker, the intelligent 12KV Outdoor Vacuum Circuit Breaker, the versatile Pole Mounted Vacuum Circuit Breaker, and the compact Outdoor Pole Top Circuit Breaker. These products can be combined within the same distribution network to provide optimized switching, protection, automation, and feeder management solutions for utility operators.

Purpose-Built for Distribution Automation Projects

The Pole Top Vacuum Switch is engineered for applications where frequent switching operations are required without the complexity of integrated protection relays. Its sealed vacuum interrupter provides stable dielectric performance throughout its service life, while the lightweight pole-mounted construction significantly reduces transportation, installation, and maintenance costs. Optional motor-operated mechanisms enable remote switching, allowing operators to isolate faulted sections or transfer loads without dispatching maintenance crews.

Designed with distribution automation in mind, the switch can be integrated with RTUs, fault indicators, communication gateways, and SCADA platforms. Utilities can remotely monitor equipment status, execute switching operations, and improve service restoration times after outages. Its modular architecture also allows future upgrades without replacing the complete installation.
