Cast resin transformers made by SGB-SMIT:
maximum reliability
With production starting in the late 1970‘s, SGB-SMIT were one of the first manufacturers of cast resin transformers, a fact which is reflecting by our reputation for quality. Operators from all over the world appreciate the extremely high reliability of SGB-SMIT cast resin transformers, as they provide maximum safety:
• High degree of security for operators and equipment • Low environmental impact • Low operating and maintenance costs • Service over the complete life time of the transformer (from order to end of life recycling) • Acceptance of used transformers for end of life recycling with a recycled content rate of over 90%
SGB-SMIT cast resin transformers provide solutions for: • The effect of harmonic distortions • Switching surges and lightning overvoltages • Extreme environmental conditions: · Very hot climates, e.g. desert regions · Very humid regions, e. g. the Tropics · Very cold regions, e. g. the Arctic, Siberia
We set new standards for our customers‘ benefit.

Quality
With production starting in the late 1970‘s, SGB-SMIT were one of the first manufacturers of cast resin transformers. This exceptional know-how is reflected by an especially high quality score, such as an MTBF of over 2,400 years (MTBF = mean time between failures).
The extremely high quality of SGB cast resin transformers has a name: Uni|Q On the following pages, we will explain in detail the specific quality and test features which make our cast resin transformers so unique.

Thedifference
•Experiencespanningseveraldecades · Comprehensive, world-wide operating experience including international production sites. · First-class international references in all industries. · Comprehensive know-how and long-term experience in onshore wind power plants incl. special cooling system: Jet System. · Transformer system tailored to open sea conditions for offshore wind power plants with many years of operating experience: Safe-System. · Optimum solutions for all industrial applications with extreme climate conditions – no matter whether extremely hot or cold: All Climate Safe System.
•Uniquedesign · The multi-layer winding is electrically the best and most reliable option. Thus, almost all oil distribution transformer manufacturers apply this principle. Millions of them have secured the energy supply in many countries worldwide for several decades. SGB-SMIT is the only manufacturer of cast resin transformers who uses this principle! •Computerizedmonitoringoftheproductionprocess · Based on a precise analysis according to automotive standards, all relevant production parameters of each transformer are recorded continuously and compared online to the set-point values. The next production step only follows if everything is correct. · This system makes it possible to achieve a uniform level of quality over large production quantities at all locations on an international basis.
•Exceptionalinternaltestingequipment · All the common operations for routine and type testing according to international standards in our own modern test area. · SGB-SMIT is the first transformer manufacturer world-wide with internal C2/C3 test area to verify the climate class. · First transformer manufacturer world-wide with internal E2/E3 test area to verify the environmental class. · Verification of internal tests by the German inspection agency „TÜV-Süd“ or other renowned test institutes.

In regions with considerably fluctuating temperatures and severe cold snaps such as Russia, Canada or North China, transformers are subject to high strain. SGB-SMIT cast resin transformers have been used for quite some time in Siberia, where they manage power supply in residential areas at temperatures down to -50°C! SGB-SMIT cast resin transformers satisfy these requirements flawlessly.
To verify climate classification C2/C3, SGB-SMIT cast resin transformers are tested and qualified by thermal shock testing in accordance with the European body of rules and standards IEC. The test includes cooling down of the transformers to -25°C and quick re-heating.
Since2012,theC2/C3testhasbeenperformed in SGB-SMIT‘s own test chamber!
Cast resin transformers have the edge over oil transformers in that they feature a low fire hazard.
Even in case of a fire in the surroundings, the fire load is extremely low and there is no risk of permanently dangerous fire effluents.
This low ignition hazard and the self-extinguishing character to verify fire protection class F1 are proved by a test following the European body of regulations and standards IEC.

… cast resin transformers are exposed to aggravated conditions due to the salty, corrosive atmosphere. Suitability of the SGB-SMIT cast resin transformers for the appropriate environmental class E2/E3 is proved by a test according to the European body of regulations and standards IEC. While this test was formerly limited to a one-time proof on a single transformer, today, a separate test for each new turbine type is required in the wind industry – a standard which SGB-SMIT is pleased to fulfill.

Reliable. Proven. Simply fact.
Calculation examples show that the transformer operators value the transformer‘s own consumption considerably higher than its acquisition price.
Moreover, the very low maintenance costs and our long-term warranty considerably reduce operating costs, as does the taking back of used equipment free of charge
Low-loss transformers generate a lower degree of waste heat and also save costs for cooling the installation rooms. Waste heat can even be utilized by a heat exchanger.
EnvironmentalprotectionThe low own consumption, long service life (> 20 years) and reusability
of 95% of the materials used save ressources and result in a considerable
reduction of CO2 emissions.
Life-cyclecost
The life-cycle cost calculation from the customers‘ point of view regarding transformers takes all costs from procurement to disposal into consideration.
