GW1 Outdoor AC High Voltage Isolation Switch – 12kV Three-Phase Disconnect Switch with High-Strength Ceramic Insulating Posts for Outdoor Power Distribution
The GW1 Outdoor AC High Voltage Isolation Switch is an essential safety component designed for installation on outdoor high-voltage power distribution lines. Specifically engineered for cutting off or converting lines under voltage but no-load conditions, this three-phase electrical appliance provides a reliable visible gap for maintenance. The unit is composed of three separate single-pole disconnect switches, each featuring high-durability ceramic insulating posts, static contacts, gate knives, and arc angles. Built to endure harsh environments, it is suitable for altitudes up to 3000m and temperatures ranging from -25°C to +40°C, ensuring operational stability in diverse outdoor climates.
GW1 Outdoor AC High Voltage Isolation Switch (12kV / 24kV / 40.5kV)
Product Overview
The GW1 Series is a robust outdoor AC high-voltage isolation switch (disconnect switch) engineered for high-voltage power distribution lines. It is specifically designed to cut off or convert lines in power systems under voltage but no-load conditions. This three-phase electrical appliance consists of three separate single-pole units that work in synchronization to provide a visible safety gap for equipment maintenance.
