High-voltage disconnect switch GW1

AChigh-currentdouble-column

Product Overview
GW1 is an outdoor double-column vertical-opening high-voltage AC disconnector designed for distribution and catenary applications. Rated voltage options cover 12, 24, 31.5 (railway) and 40.5 kV, with rated current up to 6000 A and robust withstand capability for system protection.

Key attributes

• High current-carrying capacity and maintenance-free contact design
• Long mechanical life through low-friction contact materials
• High standardization and compatibility with pole installation types
• High protection grade for the operating mechanism (IP66DM-compatible design)

Features

• High current-carrying capacity & maintenance-free — Contacts incorporate a self-cleaning action that preserves contact quality and minimizes on-site maintenance requirements.
• Long mechanical life — Graphite silver-plating on conductor sliding contact areas provides self-lubrication, reducing operating torque and extending service life.
• High standardization — Designed for compatibility with mounting solutions across all pole types used in railway catenary and outdoor distribution systems; standardized accessories simplify interchangeability and installation/debugging.
• High protection grade for operating mechanism — Top-output mechanism removes left/right output installation errors and dimensional constraints. The mechanism output shaft uses a labyrinth sealing structure to meet IP66DM protection requirements.
