Three-phase transformers are used to convert the available 3-phase mains voltage into any load voltage. To cater for the wide range of application areas involved,these transformers are essentially available in the same kinds of designs as the single-phase transformers, e.g. Three-phase dry-type transformer: separate winding version Three-phase series transformer: autotransformer winding version Three-phase safety, isolating, mains or insulating transformer: separate winding version In terms of how the 3 coils are connected, there are various options available and each of these provides the transformers with specific properties. The vector group code is composed of the following elements: The upper-case letter indicates the higher-voltage winding (the highest voltage in terms of operation). The lower-case letter indicates the lower-voltage winding. The brought-out neutral is indicated by means of N or n (depending on voltage level). â?¢ The distinctive number indicates the phase angle of the lower voltage in relation to the higher voltage (distinctive number multiplied by 30). The following winding connection options are available Delta: D, d Wye (or star): Y, y Zigzag: Z, z Example: Dyn5 Higher-voltage winding is delta-connected. Lower-voltage winding is star-connected with a brought-out neutral. The lower voltage lags behind the higher voltage by 150�° (5 x 30�°). Unless specifically requested otherwise, the transformers are configured with a double-star connection and a brought-out neutral (vector group Yyn0); for autotransformers the vector group is YNa0. Our three-phase transformer range includes all our standardised types for the 25 30.0 kVA performance range and a frequency of 50/60 Hz

1. The transformer core is made of imported high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current. The core is� tightly� bound to ensure the compactness and reduce noise. 2. The high and low voltage windings are� made of oxygen-free copper. The low voltage winding of 500KVA and below is of double-layer cylinder structure,� of 630kVA and above adopt double helix or four helix structure. High-voltage winding adopts multi-layer cylinder structure. 3. Dyn11 is used in the transformer connection group to reduce the influence of harmonics on the power grid and improve the quality of power supply. 4. The transformer is a fully sealed structure, with three coats of primer and one coat of finish paint applied on the inner and outer surfaces. The product is salt fog proof, moisture� proof and fungus-proofing, beautiful, durable and reliable 5. The measured noise value is lower than the standard and maintenance free under normal operation.

D363 & D364 range of current transformers are combination designed 3 CT in 1, save more space comparing general unit CT, suitable for primarycurrent 75A to 600A, supporting the use of molded case circuit breaker according to the rated current size.

On the basis of the S9 series, the S11 series products have an average no-load loss of 20%. The no-load current is 70-85% lower than the S9. The temperature rise is reduced by 10K, and the service life is more than doubled. Even under the load of 20%. it can still be used for a long time. The running noise is reduced by 2-4 decibels. High and low voltage windings, body assembly, fuel tank structure, protection device, etc. are similar to S9 series transformers. It also adopts non-suspension structure, adopts vacuum drying, vacuum oil filtering and oil filling process, adopts corrugated oil tank, and has no oil storage cabinet and other structures.

66KV series product line has found a far-flung avail not only in agricultural grid modification within urban and rural areas, but also in industrial or mineral enterprises. Till now, the corporation has formed its series and commercially scaled production and the product line runs well and thereby is highly appraised by our popular users. ã??ã??The transformer body is reliably positioned for ensuring that no dislocation occurs with the transformer and no deformation occurs with the windings during long-distance transportation or during long-term operation. Without the need of core suspension and being maintenance free, this product line may be used just via direct grid connection
