Voltage range notes

  • Product identity: GW9-[blank](W) Series Outdoor High-voltage Disconnecting Switch.
  • Core duty: outdoor AC no-load isolation for 50/60 Hz, 6.6-24 kV systems.
  • 35 kV rows come from the GW12-33kV additional model table; 36 kV rows come from the GWD2 dimension table.
  • The 33 kV porcelain product photo is visual material only; electrical selection follows the rating table rows.
  • Model suffixes such as /1000 and /1200 are kept exactly as shown in the supplied tables; confirm the final model code during quotation.

GW9 rating data

Core GW9-12/24(W) rows stay separate from related model groups and additional variants to avoid treating every voltage as the same model family.

Structure and product variants

Confirmed structure notes and selected visual variants from the prepared assets.

Structure notes

  • GW9-12/24(W) is a single-pole switch type with normal and anti-pollution versions.
  • Main assembly includes frame, support insulator, conductive part and operating mechanism.
  • Each pole has two blades. A pressure spring and adjusting nut maintain contact pressure near the contactor base.
  • Blade support structure locks after closing to support dynamic and thermal stability under normal or short-circuit conditions.
  • Anti-pollution type is intended for serious pollution areas.
