GW10 High Voltage Disconnect Switch

1.GW10 High Voltage Disconnect Switch: Reliable Power Grid Protection

When you need a robust solution for high-voltage busbar isolation, the GW10 High Voltage Disconnect Switch stands out. Designed for 126–550 kV transmission networks, this outdoor disconnect switch ensures safe electrical isolation in substations, power plants, and industrial grids. Its single-column vertical pantograph design, corrosion-resistant materials, and compliance with IEC 62271-102 make it ideal for harsh environments—from coastal salinity to extreme temperatures.

3.Key Features & Advantages

1. Durability in Harsh Conditions

The product uses stainless steel components and hot-dip galvanized steel to resist rust, pollution, and salt fog. Its aluminum alloy profile enhances heat dissipation, ensuring stable performance even in desert or coastal areas.

2. Low Maintenance & High Efficiency

With a maintenance-free design and self-cleaning insulators, this switch reduces downtime. The short friction travel during operation minimizes wear, while bent copper plates simplify repairs.

3. Optimized Safety

Grading rings and shields at contacts ensure even electric field distribution, reducing radio frequency interference. Externally compressed stainless springs provide stable pressure for reliable disconnection.

4. Flexible Installation

Mountable on both base sides, the switch adapts to space-constrained substations or retrofits.

4.Real-World Applications

Be used in a wide range of industries.

 

Industrial Plants

Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.

Substation

Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.

Commercial Buildings

Retrofit aging systems in hospitals or malls with silent (<45dB), flame-retardant capacitors that meet NFPA 70 fire codes.

 

5.How It Works?

The GW10 High Voltage Disconnect Switch operates via a vertical pantograph mechanism. When activated, the stainless steel arms lift the contacts vertically, breaking the circuit without arcing. This design ensures smooth operation even after 10,000+ cycles.

6.Manufacturing & Quality Assurance

• ISO 9001-Certified Production: Every switch undergoes 23+ quality checks, from raw materials to final assembly.
• Rigorous Testing: Dielectric strength tests (up to 550 kV), seismic simulations (IEEE 693), and salt fog corrosion tests.
• Patented Innovations: 12+ patents in insulator materials and contact spring technology.
