Product Description


20kv 160kva nltc SC(B) Type Cast resin Dry type Transformer
1)Low loss and low noise
2)highly withstands short-circuit and lightning impact
3)CE certification



Application Of Products

     Our SC(B) series epoxy resin cast dry transformer is cast under vacuum with thin insulating bands automatically . The core is made of high-permeable grain-orientated silicon sheet and cast with imported epoxy resin. Thanks to advanced technology, quality raw materials , scientific management, and perfect inspection means ,our products have the following features:

             The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin. It has good mechanical properties, is free of crack and inner bubble and has low local discharge, high reliability, and long service life.

              The high-and  low-voltage systems are cast under vacuum, thus the coil will not absorb moisture; the clamps of core are subjected to corrosion-resistant treatment and it may run under high temperature or other serious environments.

                Flame retardancy , explosion-proof and no environmental contamination. The insulating materials in the coil such as glass fiber are self-extinguishing and they will not cause fire by the arc resulted from short-circuit . The resin will not generate toxic or harmful gas under high temperature.

                 Gas duct is embedded inside it to enhance the radiation power and over-load capacity.

                   Low loss and low noise. The core is lapped with 45 full-miter  and the step-type lamination effectively improves distribution of magnetic flux at core corners, and greatly reduces the no-load loss and the nose level.

                  It highly withstands short-circuit and lightning impact.

                   Small in volume, light in weight, safe in running and free of maintenance.

                   As per users' requirements the transformer may be provided with casing and blower fan.

Transformer Characteristics
20kv 160kVA Nltc Sc (B) Type Cast Resin Dry Type 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).
