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.
