Product Description

Specification

The Outdoor Pole-Mounted Vacuum Circuit Breaker is a robust medium-voltage switching device designed for overhead power distribution systems in substations and grid networks. It utilizes a vacuum interrupter within composite insulation materials (e.g., silicone rubber and engineering plastics) to reliably break and make electrical circuits under normal or fault conditions, such as overloads and short circuits. This breaker supports remote control via integrated intelligent controllers and is compatible with automation systems for real-time grid monitoring. Suitable for altitudes up to 3,000 meters and temperatures ranging from -40°C to +85°C, it ensures safe operation in harsh environments while replacing oil-insulated breakers for eco-friendly performance.

Key Features

High Reliability: Vacuum interruption technology ensures efficient arc quenching with minimal maintenance, offering up to 20,000 mechanical operations and a long     service life.
Compact Design: Pole-mounted structure with lightweight composite insulation (e.g., silicone rubber) enables easy installation on poles or towers, saving space     compared to conventional breakers.
Smart Compatibility: Integrates with controllers for automation functions like remote switching, fault detection, and auto-reclosing, supporting communication via   GSM, fiber optics, or Ethernet.
Environmental Resilience: Operates reliably in extreme conditions, including high humidity, pollution level III areas, and wind speeds up to 34m/s, with options for   high-altitude adaptation

Applications

Urban and Rural Grids: Protects 10kV-35kV overhead distribution lines by interrupting fault currents and managing load switching.
Substation Control: Serves as a primary switching device in substations for circuit isolation and capacitor bank control.
Renewable Energy Integration: Safeguards connections in solar or wind farm networks where frequent operations are required.
Industrial Power Systems: Provides backup protection for factories and mining facilities with medium-voltage supply lines.
