Product Description

ZW20-12F Outdoor high voltage intelligent column demarcation vacuum circuit breaker
Product Overview

ZW20-12F Outdoor High-Voltage Vacuum Circuit Breaker Overview
The ZW20-12F is an intelligent outdoor vacuum circuit breaker designed for 12KV power distribution systems. It integrates protection, control, and automation functions, ideal for fault isolation in overhead lines and enhancing grid reliability. Its compact design, durability, and smart features make it a key component for modernizing power distribution networks.

Key Features

1. Intelligent Boundary Control
   Equipped with a built-in smart controller, it enables remote communication and automated operations to swiftly detect and isolate single-phase grounding faults and phase-to-phase short circuits, minimizing outage impact on non-fault areas.
2. Compact and Robust Design
   Features a fully sealed enclosure filled with SF6 gas for enhanced insulation. Its lightweight and space-saving structure allows easy pole-mounted installation, suitable for harsh outdoor environments.
3. Low Maintenance
   Modular design with a maintenance-free structure reduces operational costs. The spring-operated mechanism ensures high reliability for frequent switching operations.
4. Environmental Adaptability
   Resistant to moisture, pollution, and extreme temperatures (-45ºC to +45ºC), ensuring stable performance in high-altitude regions and diverse climatic conditions.

Applications

• Grid Responsibility Demarcation: Installed at user entry points or branch lines to isolate faults and protect the main grid from downstream disturbances.
• Urban/Rural Grid Upgrades: Enhances automation and reliability in overhead line systems, accelerating fault response and recovery.
• Industrial Power Supply: Safeguards critical equipment in factories and mines by enabling rapid fault isolation in high-demand scenarios.
• Renewable Energy Integration: Supports distributed energy systems with grid-friendly protection and control, ensuring seamless renewable energy adoption.

Combining intelligence, adaptability, and reliability, the ZW20-12F elevates grid safety and operational efficiency, making it a cornerstone of smart power infrastructure.
