the clean technology
The Challenge:
Environmental Safety & Security
Environmental protection demands are today
constantly rising. Ever more frequently, dry type
transformers user specifications are focused on
creating minimum environmental contamina-
tion and providing the very lowest flammabili-
ty risks. For this reason, our transformers must
today constantly meet more stringent parameters
with respect to electrical system demands, as
well as more extreme operating conditions. Glass fibre reinforcement
Applications today include: high-rise office and eliminates all risk of cracks
public buildings, nuclear power plants, offshore and provides the highest
petrochemical platforms, and high output mechanical strength
industrial process plants.
Development of many new technologies has
enabled our transformer designers to apply
modern materials with the very latest of pro-
cesses, increasing the transformers durability
while ensuring unprecedented product reliability.
Thermal shock proof
If any of the following demands form part of even at the highest and
your transformer application, then ABB has the lowest temperatures

No environmental or human
contamination risks
Non-explosive and extreme fire resistance
Heavy loading cycles (from cold starts to
full loading)
High short circuit withstand Smooth surfaces restrict
Exposure to extreme conditions (arctic, dust accumulation
tropic, chemicals, moistures etc)
Harmonic overloading, over-voltage peaks
