Outdoor Sectionalizing Vacuum Load Break Switch 12kV

Product Overview

• Professional Sectionalizing & Switching Performance：Engineered for 12kV outdoor AC systems, it excels in making/breaking load currents and closing short-circuit currents, with a vacuum arc-extinguishing core delivering stable, excellent breaking performance and strong adaptability to frequent operation scenarios.
• Dual-Component Integrated Intelligent Design：Consists of a high-quality FZW28-12 vacuum load break switch and a dedicated controller, connected by aviation-grade sockets and outdoor sealed control cables. The sealed connection ensures anti-interference, waterproof, and dustproof performance, guaranteeing reliable operation in harsh outdoor environments.
• Precise Fault Detection & Sectionalizing Capability：Reliably detects mA-level zero-sequence currents and phase-to-phase currents in the distribution network, accurately distinguishing internal and external line faults of the sectionalizing point. This realizes targeted fault isolation and protection, minimizing power outage ranges and improving the reliability of urban and rural power grid power supply.
• Ideal for Grid Automation & Frequent Operation：Optimized for automated urban and rural power distribution networks, it perfectly matches grid automation protection systems; the mature vacuum arc-extinguishing structure and stable operating mechanism make it suitable for long-term frequent switching, meeting the operational needs of substations and industrial and mining enterprises.
• Robust Outdoor Engineering Design:Adopts a fully sealed and reinforced housing structure, with excellent resistance to extreme temperatures, humidity, wind, and moderate pollution. It features a compact volume, light weight, and easy pole-mounted installation, reducing on-site construction and maintenance difficulty.
• Low-Maintenance & Reliable Operation:The vacuum arc-extinguishing chamber has no gas leakage or combustion risks, and the internal components are wear-resistant and anti-aging. The product is designed for maintenance-free operation under normal use, eliminating regular servicing and reducing the lifecycle operation and maintenance costs of the power grid.
• Wide Compatibility & Scenario Adaptability:Suitable for seamless integration with the protection systems of substations, industrial and mining enterprise power distribution networks, and urban/rural automated grids, with flexible matching capabilities for different types of 12kV outdoor distribution line configurations.
