1. Introduction:
Our wound cores are widely used in distribution transformers, especially for s13 type energy-saving transformers in china; we could provide our customers with single phase wound cores, three phase wound cores; the capacity range from 10kva to 2500kva; due to its particular technology craft, its performance is better than traditional stacked cores, especially for pole-mounted single phase transformer.
2.Manufacturing requirements:
Tolerance: see demonstrated graphic; the specified requirements should be coincide with customers drawings;
The single-phase pole-mounted distribution transformers(single phase transformer) are specifically designed for
the decentralization distribution network of servicing residential overhead distributior loads of town and countryside.
They are also suitable for light and diversified power applications,
These transformers are designed for the application conditions normally encountered
on electric utility power distribution systems.
Offers 2 basic transformer types and two kinds of metal core types Conventiona type and
Complete Self Protect type, and for the transformer core
Two types of materials are available: C.RGO. wound core and amorphous meta core.

Switching Power Supplies ( smps ), Rainproof , Water proof & Non Water proof, dc/dc converters, battery chargers and transformers
Dear Sir / Madam,
We Would like to introduce ourselves as manufacturers of industrial /
professional grade switching power supplies.
Organizations manufacturing Industrial Electronic Instruments,
Telecoms and Process Control equipmentâ??s require compact, efficient,
and rugged switching power supplies and LED Drivers, DC/DC Converters
at a most competitive price. We as an Indian manufacturer have given
utmost attention to the cos
t without compromising with the quality.
Our power supplies are being used by all over the country by all big
OEMâ??s. Feature wise our power supplies are equally comparable to any
imported power supplies available in the country. These units have all
in- built protections along with very high MTBF.
We also manufacture customized power supplies as per specifications
provided by our valued customers.
For further information, kindly visit our website www.nacei.com,
www.powersuppliesindia.com
We shall be obliged if we get an opportunity to serve you.
Kindly let us know your specifications along with quantities to
proceed further in this regard.
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
