Product Description

Product Description
12KV Pole-mounted Distribution Transformer
12kv Pole-Mounted Oil Immersed Distribution Transformer
Introduction
    The performance of our S9 S10 S11 S13 S14 series  three-phase oil-immersed transformer conform to the standard of GB 1094-1996 "Power Transformer " and GB/T6451-2008 "Technical Parameter and requirements of Three-phase Oil-immersed Power Transformer". The iron core is made of quality cold -rolled silicon steel sheet , and the coil is made of quality oxygen-free copper, featuring good outlook and safe running . The products are widely used in power transmission and distribution of industrial and agricultural power networks.

Main function and features
     In Western countries, Southeast Asia, and North and South America, single-phase transformers are widely used as distribution transformers. Single-phase transformers have significant advantages as distribution transformers, as they can reduce the length of low-voltage distribution lines, reduce line losses, and improve power supply quality. The characteristics of this transformer are the use of column suspension installation, small size, low infrastructure investment, and simple maintenance.

Suitable for rural power grids, remote mountainous areas, scattered villages, agricultural production, lighting, and electricity consumption, as well as energy-saving transformation of railway and urban power grid column mounted distribution lines.

Transformer Characteristics
12kv Pole-Mounted Oil Immersed Distribution Transformer
Winding .
The winding must be especially protected - both against high electrical stress due to
external over voltages and against mechanical overloads by short circuits. They are made of copper or aluminum. Low-voltage windings are made of strip or flat wire while
high voltage windings are manufactured from round or profile wire. ("diamond-dotted paper") bonds the winding into a compact block
while drying and increases the short-circuit capacity additionally.

Magnetic Core lamination.
The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steel lamination insulated on both sides,
guaranteeing low losses and low noise. These values are even improved by laser treatment. It is protected on the surface with a
flash-proof varnish in order to prevent the sheet from corrosion and to reduce the noise.

Oil tank.
Whether during transport or operation -the tank must be absolutely tight under mechanical stress. We have vast constructional experience, the most modern calculation methods and high-quality welding work. Special attention is paid to
corrosion protection. Pretreatment of the surface is processed by phosphating pickling, contributes to corrosion protection, just
like multi-coating with preset drying times for each layer. On request, hot-dip galvanization provides for even better protection

Test lab
Testing are conducted for every transformer before delivery.Tests are classified to be routine tests and type test.
A - Routine tests: According to IEC 60076 standard , the following tests must be carried out for all units of the transformers
a- Measurement of winding resistance .
b- Measurement of voltage ratio and check of phase displacement.
c- Measurement of short circuit impedance and load losses.
d-Measurement of no-load losses and current .
e-Dielectric routine tests including the separate source AC voltage withstanding test and short duration induced over voltage withstanding test ( ACSD ) .

B - Type tests :
The following tests shall be carried out
a- Temperature rise test
b- Lightning impulse test

C - Special tests :
a- Determination of noise level according to IEC 60551 .
b- Oil leakage test
c- Overload test at 150 % rated current for one hour after temperature rise test ( top oil temperature rise and winding temperature rise must be measured and recorded in the report test also hot spot temperature rise must be calculated and recorded on the report test ) .
d- Short Circuit Dynamic stability Test (test report from independent and accredited laboratory for similar transformer will be accepted).
