Quick Details
Specifications
In the electric power system, large capacity transformer is mainly oil immersed power transformer, its stable operation is important to ensure the safe operation of the power system. At present, the nitrogen-injection fire extinguish in device with its exclusive feature of prevention first and combination of fire prevention and fire fighting, has become an important fire control facility for oil immersed power transformer.
BPZM is the newly device which are specially applied for oil immersed transformer.
