GW4 Series Outdoor High Voltage Isolating Switch The GW4 Series is a robust and reliable outdoor high-voltage isolating switch designed for use in transmission and distribution systems up to 245 kV. It serves as a critical component in electrical networks, providing visible isolation for maintenance, circuit segmentation, and load switching under no-current conditions. Design and Construction The GW4 series features a double-break, center-rotating structure, ensuring high mechanical stability and electrical performance. The switch consists of two insulator columns supporting movable contacts that rotate horizontally to open or close the circuit. This design minimizes mechanical stress and enhances operational reliability. - Base Frame: Made of hot-dip galvanized steel for corrosion resistance, ensuring durability in harsh outdoor environments. - Insulators: High-strength porcelain or composite insulators provide excellent dielectric properties and resistance to pollution, UV, and extreme weather. - Contacts: Self-cleaning silver-plated contacts ensure low contact resistance and reliable conductivity. - Operating Mechanism: Manual, motorized, or motor-assisted operation options are available, with optional remote control for automation. Key Features 1. High Breaking Capacity: Suitable for disconnecting rated currents and withstanding short-circuit forces. 2. Maintenance-Free Design: Minimal lubrication points and corrosion-resistant materials reduce upkeep. 3. Flexible Configuration: Can be installed in horizontal or vertical layouts, adapting to substation space constraints. 4. Safety Compliance: Meets IEC 62271-102 and other international standards for high-voltage switches. Applications - Substations: Isolates transformers, busbars, and feeders for safe maintenance. - Renewable Energy Farms: Disconnects solar/wind power connections. - Industrial Plants: Segments high-voltage circuits in factories. Advantages - Long Service Life: Engineered for 30+ years of operation. - Easy Installation: Pre-assembled modules simplify deployment. - Environmental Resilience: Operates in temperatures from -40°C to +55°C and withstands heavy wind/ice loads. In summary, the GW4 Series offers a cost-effective, durable solution for high-voltage isolation, combining safety, reliability, and adaptability for modern power systems.
