66kV Three-phase ,oil-immersed ,two Windings, on-load Tap Changing Power Transformer

Product Details

66kV three-phase ,oil-immersed ,two windings, on-load tap changing power transformer

S(F)Z11- 66kV two windings, on-load voltage regulation transformer

(1) Reasonable construction: use modern computer technology to analyze the characteristic about electric, magnetic, force and thermal for transformer, and on this basis to design construction drawings, making product construction be more reasonable and completed.

(2) Advanced performance: in addition to that product performance can meet relevant national standard, special design can also perform as per user requirement and PD level is obviously less than specified value of national standard.

(3) Safe and reliable: Winding insulation structure, ampere-turn arrangement and cooling system are designed on basis of analysis for transformer electric, magnetic, force and thermal performance, improving transformer ability to withstand over-voltage and short-circuit current and the local overheating does not occur.

(4) High quality components: select high quality components from domestic or abroad as per user requirement, making product performance will be more reliable.

(5) Worry-free for user: beautiful appearance, no leakage and free- untanking.
