Frequently Asked Questions (FAQ)

Q1: What are the primary application fields for the GW4-40.5 series?
A: It is widely applied in photovoltaic power stations, wind power stations, substations, and SVG static var generator supporting equipment for opening and closing circuits under no-load conditions.

Q2: How does the switch prevent dangerous misoperations like live grounding?
A: The switch comes equipped with integrated grounding blades and built-in mechanical interlocks, effectively preventing "closing lines with live wires" and "earthing wires with live power" while removing the need for operators to handle separate external grounding wires.

Q3: What operation and grounding configurations are available?
A: It can be flexibly configured with single-side grounding, double-side grounding, manual mechanisms, electric mechanisms, and integrated installation lightning arresters based on project requirements.

Q4: What are the environmental and altitude limits for normal operation?
A: It is designed for altitudes not exceeding 3000m, ambient temperatures between -40°C and +40°C, wind speeds up to 35m/s, earthquake intensities up to 8 degrees, and is well-suited for polluted areas near cities and industrial zones (excluding locations with fire/explosion risks, severe vibrations, or strong chemical corrosion).
