Outdoor Isolation Switch with Pure Copper Manual Changeover and PV Safety Integration

Product Description

Product Description

The Outdoor Disconnecting Isolation Switch is a high-voltage device designed to safely isolate electrical circuits for maintenance, inspection, or emergency shutdown. Engineered for outdoor applications, it features strong mechanical strength, excellent insulation performance, and high resistance to environmental conditions.

With a robust galvanized steel structure and weatherproof design, this switch ensures reliable operation in substations, transmission lines, and distribution systems. It provides visible and secure disconnection, minimizing risks during power system servicing.
 

Key Features of Outdoor Disconnecting Isolation Switch

• Visible Isolation Point
  Provides a clear and safe disconnection, ensuring visual confirmation for maintenance and safety compliance.

• Robust Weather-Resistant Design
  Engineered for outdoor environments with high resistance to UV, rain, dust, and temperature fluctuations.

• High Dielectric and Thermal Performance
  Maintains stable operation under high voltage and high current, with excellent insulation properties.

• Reliable Mechanical Structure
  Features strong mechanical strength and smooth operating mechanism, with low operating force.

• Advanced Material Use
  Made with epoxy resin, silver-plated contacts, and corrosion-resistant hardware for long service life.
   

Environmental Conditions for Use

• Installation altitude should not exceed 1000 meters.

• Ambient temperature range: maximum +40°C, minimum -30°C.

• Relative humidity: daily average ≤95%, monthly average ≤90%.

• Seismic resistance: designed to withstand earthquakes up to magnitude 8.

• The environment should be free of fire hazards, severe pollution, chemical corrosion, or intense vibration.
