HAMBURG WIRGES KIRCHAICH DRESDEN MARCHTRENK KECSKEMÉT SHANGHAI
Winding of a glass fiber
cast coil.
max. diameter 1,60 m
The design of the HV
coil does not allow the
formation of any cracks
due to the high
mechanical strength of
the glass fiber
reinforcement even
under the most severe
short circuit conditions
or during extreme
temperature shocks
Example: Fibreglass boats
Windmill blades

HAMBURG WIRGES KIRCHAICH DRESDEN MARCHTRENK KECSKEMÉT SHANGHAI
Copper or Aluminum windings
insulated using a glass fiber epoxy resin
laminate
The HV coil is cast into moulds under
vacuum process with pure epoxy resin
The LV coil is cast into moulds or VPI
design
The manufacturing process ensures a
void less insulating system of the highest
quality
The coil’s are partial discharge free and
impulse voltage proof
The HV coil can be designed with air
ducts to cool the windings
Technology and Concept
HAMBURG WIRGES KIRCHAICH DRESDEN MARCHTRENK KECSKEMÉT SHANGHAI
Technology and Concept
- Tapping links are brought out onto the
outside face of each coil
- The HV coils are hardly inflammable and
self extinguishing.
- Massive u-profiles for clamping the core and
pressing the coils
- Massive undercarriage to carry the weight
of the transformer
- Wide temperature range in service and
during transport and storage
- suitable for difficult environments like : "high
humidity", "aggressive atmosphere" e.t.c.
- low no load and load losses
- low sound pressure level
HAMBURG WIRGES KIRCHAICH DRESDEN MARCHTRENK KECSKEMÉT SHANGHAI
- Enclosures for all kind
of application indoor
or outdoor can be
supplied including
voltage / current
transformers, different
temperature relays,
surge arrestors …

Advantages of cast resin transformers
• Overloads possible like - Extra heavy duty traction
• Fire protection, class F1 hardly inflammable and self
extinguishing
• Environmental Class E2 / Climatic Class C2
• Partial discharge free up to 36 kV
• High impulse withstand voltage up to 200 kV possible
• High mechanical strength Low sound pressure level do
to special core clamping and low core induction
• Low no load and load losses do to high grade core
material, low core induction and copper windings
HAMBURG WIRGES KIRCHAICH DRESDEN MARCHTRENK KECSKEMÉT SHANGHAI
Advantages of cast resin transformers
• Corrosion Protection, all steel construction parts like the
core clamps or the wheel base are hot dip galvanised,
screws are of stainless steel
• By using fans power increase of up to 50%
Advantages compared to Oil filled units
• No maintenance under normal environmental conditions
• Short circuit proof design-windings are embedded in resin
• No need for drain pit and oil checking
• No need for fire protection room design
