The GW4-10/15kV-B is an anti-bird variant of the GW4 outdoor high-voltage disconnect switch, optimized for regions with frequent bird activity. Its design reduces the risk of bird-caused flashover — a common outage cause on exposed 10kV/15kV overhead lines.
Built per GB 1985-2014 and TB/T railway industry standards, the switch features a hot-dip galvanized steel frame, copper alloy contacts and high-strength post insulators, operating from -40°C to +70°C at altitudes up to 4,000 m.
Installation follows standard practice: pole-side or independent foundation mounting with manual, motorized or hand-crank operating mechanisms.

Frequently Asked Questions
What does the anti-bird design prevent?
Birds perching or nesting on switchgear can bridge live parts and cause flashover trips. The anti-bird variant's geometry and protective details reduce this risk on exposed lines.
Which voltage classes are available?
10kV and 15kV outdoor systems.
Which standard applies?
GB 1985-2014 for HV AC disconnectors, plus TB/T railway industry standards.
