Product Introduction

The universal PGS series pole-mounted load break switch is suitable for systems with rated voltages of 12kV, 24kV, and 33kV, rated currents of 400A/630A, and frequencies of 50/60Hz. It can be used for load operation, line overload interruption, and switching operations of electrical systems. The switch can be equipped with a controller featuring the most advanced technical parameters. The PGS-A type is a manual load break switch for user selection; the PGS-M type is an intelligent load break switch for user selection. When a fault occurs on the distribution network line, it can automatically trip; it supports manual operation, electric operation, and remote operation; the electric controller is installed in a stainless steel enclosure and can be used under various environmental conditions.

Operating Environment

1. Air temperature: Maximum temperature: +40°C; Minimum temperature: -20°C.

2. Humidity: Monthly average relative humidity: 95%; Daily average relative humidity: 90%.

3. Altitude: Maximum installation altitude: 2500 meters.

4. No obvious corrosive or flammable gases, vapors, or other contaminants in the surrounding air. 5. No frequent severe vibration.Functions

    1. SF6 gas insulation: SF6 is a non-toxic, non-flammable electrical insulating gas with excellent arc-extinguishing performance.
    2. Bushing diversity: In addition to standard porcelain bushings, a variety of rubber bushings are also available.
    3. Visible open/closed status: The color indication of the main contact position indicator is clearly visible (green indicates open, red indicates closed); this indicator is always directly connected to the main conductor, ensuring accurate reflection of the conductor's actual status.
    4. Fast operation: A spring-energy storage operating mechanism is adopted to ensure rapid opening and closing operations (no more than 1 second).
    5.  Can be equipped with a controller: The electric controller is standard, allowing for local operation at ground level or remote operation from the master control system via the RTU screen.
    6. Robust switch construction: The switch body is manufactured from sturdy, corrosion-resistant materials, ensuring a long service life (30 years) and pole-mounted equipment characteristics.
    7. Standards: Sufficient SF6 gas is filled and sealed before leaving the factory; tested in accordance with IEC 60265 and GB 3804 standards.
