Oil Load Break Switch – Reliable Switching for Oil-Immersed Distribution Transformers

Our Oil Load Break Switch is specifically designed for use in oil-immersed distribution transformers, providing safe and reliable on-load switching capabilities within medium-voltage power systems. This internal switch allows operators to isolate, energise, or change transformer tap positions under load conditions, ensuring efficient voltage regulation and safe maintenance operations.

The switch is fully enclosed in insulating transformer oil, which serves both as a cooling medium and an arc-extinguishing agent. Constructed with high-quality copper alloy contacts, arc-resistant insulation materials, and a robust rotary mechanism, the oil load break switch ensures smooth operation, minimal contact wear, and long-term mechanical durability.

Key Features:

  • Voltage Class: 10kV / 20kV / 35kV
  • Current Rating: 200A to 630A (customizable)
  • Switching Type: Load break, oil-immersed
  • Structure: Rotary mechanism with visible contact positioning
  • Contact Material: Copper alloy with arc-resistant design
  • Installation: Internal mounting for oil-filled transformer tanks
  • Operation: Manual or motor-driven (optional)
  • Insulation Medium: Transformer-grade mineral oil

Applications:

  • Oil-immersed distribution transformers
  • Compact transformer substations
  • Renewable energy systems (wind/solar)
  • Urban and rural medium-voltage distribution networks

Advantages:

  • Enables safe load switching without de-energising the system
  • Arc-extinguishing oil chamber ensures prolonged service life
  • Compact and modular design for easy integration into the transformer tank
  • Customizable voltage and current ratings to meet project specifications

Our oil load break switch is a vital component for enhancing safety, flexibility, and efficiency in medium-voltage transformer applications.
