Key highlights
�Majority owned subsidiary of Elettromeccanica Italy with Sharika Enterprises as equity based joint-venture partner providing plant management and looking after marketing activities across India.
�The company caters to the requirements of the entire Asian market.
�Elettromeccanica Italy, established in 1901, has been manufacturing Cast Resin Transformers since 1983. The company has supplied 30,000 MVA in 50 countries, including 350-400 transformers to India with 33/0.415 kV 200-3000 kVA ratings for the Delhi Metro Project.

Why foil windings?Conventional Round Windings�Inter-turn voltage is variable and, at
times, can exceed substantially�Higher chances of inter-turn
insulation failure due to voltage breakdown.
Foil Windings�Inter-turn voltage is always constant
as each layer consists of only one winding turn.
�Minimal failure chances of inter-turn layers.
Why aluminium?The thermal expansion coefficients of
aluminium and the used cast resin are
so similar that thermal stresses due to
load changes are kept to a minimum.

Product RangeEIPL manufactures all kinds of cast resin transformers for power, distribution, rectifier, etc. These transformers can be manufactured with copper or aluminum winding or both as per customer requirements. The transformer range includes:
Low voltage transformers LV/LV Rating up to 2500 kVA nominal voltage up to 1.1 kV
Distribution transformers MV/LV Rating up to 3150 kVA and nominal voltage up to 36 kV
Power transformers HV/LV HV/MV Rating up to 10 MVA and nominal voltage up to 36 kV
Parts/accessories of Core
The core is built up of cold rolled grain oriented steel sheet with low specific losses, insulated on both sides by a thin inorganic coating (Carlyte). The sheets composing the core are cut as step lap (at 45°). Uniform pressing, stiffness and solidity of the columns assure a low noise level.
Medium Voltage Winding
High voltage windings are made of electrolytic aluminum conductors (wire or foil strip, depending upon power and voltage requirements). It is possible to produce copper windings as well. The windings are inglobed under vacuum in class F epoxy resin (class H is also possible on specific demand). The accuracy of execution of these processes ensure windings free from partial discharges.
Low Voltage Winding
Low voltage windings are made of strip or foil (copper or aluminum conductor, depending upon power and voltage requirements). Class F/H insulating material is used.
Standard Accessories
Skid under base or truck with bidirectional wheels, lifting lugs, earthing terminal.
Temperature Monitoring Unit
Temperature monitoring is essentially used for safe operation of cast resin/dry type transformers. It is suitable for control room as well as marshalling box installations and is built for long and trouble-free operation under extreme conditions of service.
Force Ventilation System
This is an optional accessory and is used where ventilation is either not sufficient or to increase temporarily rated power of the transformer.
Enclosure
The kind of enclosure is decided as per transformer size and the place where the transformer is to be installed. Frame for door thickness: 2mm/1.6mm. Side, front back panels and top sheet thickness: 1.6mm thick. Castle lock, looking glass and other accessories are provided as per client requirements.
cast resin transformers
Aluminium Windings for Cast Resin Transformers
Parameters Copper Aluminium AdditionalInformation/Calculation
Coefficient of linear expansion (Resin)
The difference between the relative linear expansion of aluminium and resin is quite close while that of copper and resin is quite high. Thus, the chances of void creation or cracks in insulation are higher in copper winding as compared to aluminium winding.
6 6 6 Conductivity (σ) 56×10 S/m 35×10 S/m 1.6×35×10 = 6 56×10 S/m
With a higher cross-section area of Al conductor (1.6×Cu conductor) provided same conductivity and resultant load losses are easily maintained.
Thermal Storage 0.092 cal/g/°C 0.214 cal/g/°C3 3capacity 8.9 gm/cm 2.7 gm/cm Density
1 1.6 CS Area Factor8.9×0.092 = 0.8188 0.214×2.7×1.6 Comparative
= 0.9248 Capacity
Aluminium can withstand greater surge and overload current than equivalent copper.
By taking the reasons mentioned above into account, the weight of a cast resin transformer and resultant cost gets reduced with aluminium winding as compared to copper winding. This results in lower prices for a technically superior product.

Tests
Functional Characteristics
All transformers are singularly routine tested according to IEC 60726 and equivalent IS- 11171 that include:
�Measurement of winding resistance
�Measurement of voltage ratio and check of voltage vector relationship
�Measurement of impedance of voltage (principal tapping), short circuit impedance and load loss
�Measurement of no-load loss and current
�Separate-source voltage withstand test
�Induced over voltage withstand test.
In addition EIPL also conducts special tests like:
�Partial Discharge Measurement
�Measurement of Acoustic sound level
The following type and special tests can be carried out upon request:
�Temperature rise test (Type Test)
�Lightning impulse test ( Type Test)
�Short circuit test (Special Test)
High Short Circuit Strength
A coil manufactured with epoxy resin has a robust structure and can better withstand electro-mechanical force occurring during short circuit, external impacts and abnormal vibrations.
High Overload Capacity
Due to the high terminal time constant, a coil made with epoxy resin can endure high overloads for a short time.
Fire Resistance
Epoxy coils have a self-fire extinguishing performance, safe in case of fire electrical sparks.
Compact Size
Compact size, especially in depth, can give advantage in installation room.
Environment Safe
Compared to oil immersed, resin transformers are free from environmental pollution as there can be no spill or oil leakage.
Maintenance-Free
Coils cast with epoxy resin do not suffer from deterioration of insulating property on account of humidity and moisture; furthermore there are no joints or valves making it easy to inspect and maintain the transformer.

TECHNICAL DATACast Resin Transformers
Tests
Functional Characteristics
All transformers are singularly routine tested according to IEC 60726 and equivalent IS- 11171 that include:
�Measurement of winding resistance
�Measurement of voltage ratio and check of voltage vector relationship
�Measurement of impedance of voltage (principal tapping), short circuit impedance and load loss
�Measurement of no-load loss and current
�Separate-source voltage withstand test
�Induced over voltage withstand test.
In addition EIPL also conducts special tests like:
�Partial Discharge Measurement
�Measurement of Acoustic sound level
The following type and special tests can be carried out upon request:
�Temperature rise test (Type Test)
�Lightning impulse test ( Type Test)
�Short circuit test (Special Test)
High Short Circuit Strength
A coil manufactured with epoxy resin has a robust structure and can better withstand electro-mechanical force occurring during short circuit, external impacts and abnormal vibrations.
High Overload Capacity
Due to the high terminal time constant, a coil made with epoxy resin can endure high overloads for a short time.
Fire Resistance
Epoxy coils have a self-fire extinguishing performance, safe in case of fire electrical sparks.
Compact Size
Compact size, especially in depth, can give advantage in installation room.
Environment Safe
Compared to oil immersed, resin transformers are free from environmental pollution as there can be no spill or oil leakage.
Maintenance-Free
Coils cast with epoxy resin do not suffer from deterioration of insulating property on account of humidity and moisture; furthermore there are no joints or valves making it easy to inspect and maintain the transformer.
