Applications: Focus on Insulating Oil Circulation
The OWP-BL43-200 is tailor-made for electric insulating oil circulation, a critical function in high-voltage electrical equipment. It ensures efficient heat dissipation and insulation maintenance for various applications:
- Oil-immersed power transformers (110kV, 220kV, 500kV and above)
- Oil-immersed reactors
- Oil circuit breakers
- Oil-immersed transformers (current/voltage)
The pump circulates insulating oil to absorb heat from cores and windings, preventing overheating and extending equipment lifespan. Its wide voltage range (18-32VDC), robust construction, and extreme temperature resistance make it suitable for harsh industrial environments. Constant flow control guarantees consistent oil circulation, while dry running and overload protection prevent damage during unexpected operating conditions.
