Reliable Service , 6.6 kV - 50 kVA , Oil - Immersed Transformer , Anti-lightning Impulse , Excellent Overload​


Product Description




1.Great ability of short circuit resistance
2. Cold rolled silicon steel core and oxygen-free copper wires, higher efficiency and lower loss;
3. Complete sealed structure, low maintenance;
4. Vacuum oil filling prevents air bubbles, high stability of insulation;
5. Excellent rated capacity.

6 .The cancellation of oil conservator makes the transformer more convenient to use;

The replacement of oil tube into corrugated tank makes the transformer easier to cool;

The physical property of corrugated tank increases the reliability of the transformer;

The adoption of sanforizing makes sure the robustness of long distant transportation.




The product has been widely used outside, such as power transmission and transformation system for agriculture, village, communities, mining, petrochemical enterprise, light industry area and etc.


Transformer short-circuits and overload


Current transformers shall be capable of mechanically and thermally withstanding the same over-currents and overload, for the same periods, as the associated windings of the power transformer.


 Insulation levels and short-circuiting for testing


Current transformers (including the neutral bushing CT’s on partially graded neutrals) shall withstand all dielectric tests applied to the power transformer windings, and shall be in position and in circuit during the power transformer voltage withstand and impulse tests.


Open circuits shall be avoided during testing of the transformer.


All current transformers shall be shorted and earthed in the factory and delivered to site in that condition.





The current transformer shall be tested and test certificates provided as specified in 5.2 Test by the





Terminals and locknuts


All current transformer terminals inside the power transformer shall be of the stud type and all connections shall be securely locked using lock nuts or locking plates. Steel lock washers are not acceptable.
