The Tees range of transformers are generally ‘Isolation’
types constructed on 3 phase ‘3UI’ laminations
or cut-strip assemblies with 3 dual wound coils, one
mounted on each leg. Each coil has a safety earth screen
between the windings. Interconnection of the windings
on the three legs can be arranged for all valid vector
group. Three phase autotransformers have three windings
without the safety earth screen usually connected in
the ‘Yyn0’ configuration
Power Capability :

Up to 100kVA. Higher on request |
Voltages :
|
Up To 6.6kV |
Insulation Class :
|
B, F or H Class 200 on request |
Ambient :
|
40°C max as standard. Others on request |
Temperature Rise :
|
Dependant on insulation class |

Screw or Stud, Touchproof. Flying leads on request |
Angle Frame
|
Tie-rod Frame |
 Small
assembly for transformer ratings up to 80kVA manufactured
using ‘3UI’ punched laminations |
 Large
assembly for transformer ratings from 80kVA to 100kVA
manufactured using low loss cut strip magnetic steel |
Transformers can be supplied in a range
of enclosures from IP22 to IP66
The following table indicates typical sizes
of ‘Open Style’ transformers
for various power ratings of low voltage units
(<700V). Please note these may vary slightly
as the specific voltage requirements determine
the final transformer design.

Note the inclusion of some optional components
may result in a size increase of the indicated
enclosure type

For transformers enclosed in high IP rated boxes i.e.
non-ventilated, the size of both the transformer and
the enclosure has to increase to avoid overheating.
Dimensions on request
Units with voltages greater than 700V up to 6.6KV
can be manufactured however the insulation requirements
of these transformers will require a larger build size
for the specific rating
Units can also be designed and manufactured with ratings
up to 800KVA
Instrument transformers manufactured with small VA
ratings and low regulation levels for accuracy tend
to be manufactured on frame sizes approximately 10 to
20 times their VA rating
