Integrating advanced SF6 gas insulation and arc-extinguishing technology with a specialized bypass design, it is designed to realize safe load transfer and equipment maintenance without power interruption, while boasting low power loss, excellent heat dissipation, and strong overload capacity.Compliant with international IEC standards, this switch features corrosion-resistant 304 stainless steel housing, stable mechanical performance, and flexible operation modes, making it an ideal core component for global urban and rural power grids, industrial facilities, and commercial infrastructure projects. It perfectly meets the procurement needs of overseas clients for high-quality, low-maintenance, and safe bypass switching equipment.

Core Features 

Focusing on durability, stability, and operability, the switch has distinct competitive advantages that align with the core demands of overseas purchasers:

• Permanent Corrosion Resistance: The switch cabinet is manufactured with 304 stainless steel, which achieves permanent corrosion resistance, effectively adapting to harsh outdoor environments such as coastal areas, chemical plants, and high-humidity regions, and ensuring long-term stable operation without cabinet damage.
• Stable & Durable Mechanical Performance: The main circuit operating mechanism adopts a simple toggle (inverted triangle) structure, which is not affected by high-frequency vibration, gravity, or external impact caused by earthquakes or strong winds. It features excellent operational stability, long mechanical service life, and supports both manual and electric closing/opening operations. It also has good compatibility with backup protection devices, ensuring seamless coordination in power system protection.
• Flexible Quick-Plug Bushings: Equipped with quick-plug bushings, and optional European and American self-locking quick-connect plug-in interfaces, which greatly simplifies on-site installation, disassembly, and maintenance, improving construction efficiency and reducing labor costs.
• Comprehensive CT/RVT Protection: Configured with CT/RVT protection device to prevent overcurrent and CT open circuit of current measurement devices, as well as overvoltage of voltage measurement devices, effectively protecting the switch and associated power equipment from damage, and ensuring the safe and stable operation of the power distribution system.
• Rich Monitoring & Detection Functions: Equipped with live display, counting display, and phase checking function, which facilitates on-site operation, equipment status monitoring, and fault judgment, reducing the difficulty of on-site maintenance.
• Multi-Mode Safe Operation: Supports manual operation, electric operation, on-site remote control operation; optional long-distance remote control closing/opening function, ensuring convenient, fast, and safe operation, and adapting to different on-site operation needs of overseas projects.
• Optional Fault Protection (Customizable): Optional fault detection, alarm, and automatic fault cutoff functions, which can timely identify equipment faults, issue alarms, and automatically cut off faulty circuits, facilitating quick fault handling and reducing downtime, thus improving the reliability of the power distribution system.
