Product Description

Timetric Outdoor GW5 1250A AC Isolation Switch

Timetric Electric's GW5 AC high-voltage isolating switch, a product under the renowned Timetric brand, is designed for power systems with a rated voltage ranging from 35kV to 252kV. It is used for no-load switching of high-voltage lines and electrical isolation of equipment during inspection from live high-voltage lines.

Key Specifications:

Altitude: Suitable for installation up to 1000m above sea level, with a special type designed for altitudes up to 4000m.
Ambient Temperature: Operates reliably in temperatures from -35°C to +40°C, and down to -40°C in alpine regions.
Outdoor Wind Speed: Withstands wind speeds up to 34m/s.
Pollution Resistance: Suitable for moderately polluted areas.
Ice Coating: Handles ice coatings up to 10mm thick.
Seismic Intensity: Withstands seismic intensities not exceeding 8 degrees.
Installation Requirements: Should be installed in areas free from gas, steam, chemical deposits, dust, dirt, and other substances that may impact insulation and conductivity. Avoid severe vibrations.

Product Features:

Improved Structure: Enhanced waterproof function with bearing turntable design, and added oil injection holes and adjusting screws for easier maintenance.
Brazing Process: Conductive rod and contact joints are brazed, reducing main circuit resistance and minimizing heating issues during operation. Enhanced grounding circuit reliability with soft connections.
Surface Treatment: Exposed part of the main conductor is copper-plated with silver, providing a smooth, corrosion-resistant, and durable surface.
Enhanced Shaft and Hole Matching: Copper-copper or stainless steel-copper matching improves outdoor durability. Stainless steel components and hot-dip galvanizing enhance switch corrosion resistance.
Precision Castings: Safety improvements with precision castings instead of welded parts.
Installation Flexibility: Grounding knife switch allows interchangeability on-site using a unipolar linkage mode, simplifying construction installation.

In summary, Timetric Electric's GW5 AC high-voltage isolating switch, a product under the esteemed Timetric brand, offers a reliable and innovative solution for power systems. It ensures safe operation under diverse environmental conditions and provides added convenience during installation and maintenance.
