5.2 Windings
All the low and high voltage windings aremade up of copper bands (foils) or aluminium
wire (foils) .Voltagebetween layers is low , while
layer capacity is great . Its lighting
impulsewithstand capacity is high . The reactance
of high and low voltage is the same . There is nohelical angle . For ampere turns of the high and
low voltage windings are best leveled, the
windings are capable of withstanding short
circuit . Therefore, they have high operating
reliability.
Molded with epoxy resin at high vacuum ,the high and low voltage windings have well
electrical and mechnical performance . Partial
discharge of them is less than 5pc.
High and low voltage windings can beequipped with ventilating air passages according
to requirements for heat dissipation. The isolating
resin on the surface is 2.0-2.5mm thick in average
, ensuring the temperature increase and strength
of the windings and securing the 30 years service
life .
Because of quartz powder on the epoxyresin and the glass-fiber net banded inside and
outside the windings , they have high heat-
dissipating ability , humidity-resistance and flame
resistance . There is no need to worry aboutcracking . They can work normally under the
humidity of 100% . Their flame-resistant
performance accords with the Britain BS7806F2.

7.1. General information
Due to the absence of any liquid dielectric and
the excellent fire behaviour of transformers, no
anti-fire precautions are necessary providing
the following guidlines are followed:
The transformer should not be installed in a
flood hazard area.The altitude should not be above 1000 meters
unless a higher altitude is specified at the time
of inquiry
The ambient temperature for the transformer
to be within the following limits:
- Minimum: 250C
- Maximum: +400C
Standard transformers are designed in
accordance with IEC726 for an ambient
temperature of:
- Maximum: 400C
- Daily average: 300C
Yearly average: 200C
The local ventilation should allow the
dissipation of the transformer total losses.
In highly polluted atmospheres (metal
machining oil, conductive dust), the air coming
into contact with the device should if possible be
cleaned (filtering, inlet of outside air via aducting)
The transformer even with IP21 metal
enclosure is designed for an indoor installation.
Provision should be made for access to
connectors and tapping links.
Without enclosure (IP00) (figure 1)
In this configuration, the transformer must be
protected against direct contact.
In addition:Care must also be taken to eliminate risks of
water drops on the transformer (example:
condensation from overhead pipings).
Maintain minimum clearance to the walls
according to the following table:

7.2. Ventilation
Determination of the height and area of
ventilation grills
In the general case of natural cooling (AN)
the ventilation of the substation or of the
enclosure must ensure by natural convection
the dissipation of the heat produced by the
transformers total losses.
In case of a no sufficiently ventilation
substation, appropriate ventilation will consist
of a fresh air intake opening of S section at the
bottom of the local and an air outgoing
opening S located above on the opposite wall
at height H meters above the intake opening
(figure 1 and 2).
To ensure efficient cooling of the
transformer and sufficient air circulation, it is
essential to maintain a minimum height of 150
mm under the live section, by installing castors
or an equivalent booster
It must be noted that restricted air
circulation reduces the transformers
continuous and short- term overload capacity.
Formula for ventilation (figure 1):
and S=1.10xS
P = sum of the transformers no-load and load
losses expressed in kW at 120C.
S = area of the lower air intake opening (allow
for mesh factor) expressed in m2.
S = area of the air outlet opening (allow for
mesh factor) expressed in m2.
H = height difference between the twoopenings expressed in metre.
This formula is valid for an average ambient
temperature of 200C and an altitude of 1000m
Example:
- one single transformer 1000kVA
- P0=1780W, Pccat 1200C =9140W,
i.e. P=10.9kW
If the distance between the grills=2m, then
S=1.4m2

Forced ventilation of the substation is
necessary for ambient temperatures above
200C or small or badly ventilated rooms for
applications with frequent overloads.
The fan can be controlled by a thermostat

top part of the room.

7.3. Connections
The incoming HV and LV connections can be
made from the top or the bottom.
MV side connections are made by cables
LV side connections are made conventionally by
cables, but can also be made using the very
safe alternative using Prefabricated Busbar
Trunking (PBT).
In all cases shown the cables or busbars must besupported to avoid mechanical stress on the HV
or LV terminals or HV plug in connectors.
The HV connections should be made to the top of
part of the delta connection bars. The LV
connections are made at the top of the
transformer.
Warning:
- The distance between HV cables or busbarsand the surface of the winding should be at
least 120 mm except on the flat face of the HVside where the minimum clearance will be set
by the HV terminal.
- The clearance to the outer HV delta bar shouldalso be a minimum of 120 mm.
- The resin coating, or the use of plug inconnectors does not give protection against
direct contact and the transformer must not be
touched when it is energized.
Without metal enclosure (IP00)
Standard HV and LV connections- The outgoing (or incoming) LV conductors can
be made from above or below (figures 1 and
2).
- The outgoing (or incoming) HV conductors canbe made from above or below (figures 1 and 2)
In case of an outgoing (or incoming) conductors
from below it is necessary to put a spacer
HV connections with plug in connectors (figure3)
LV connections using prefapricated electricalducting (figure 4)
On site installation is simplified as far as
possible, with very easy fitting, assembly and
dismantling:
- The transformer is delivered pre-equipped withthe PBT connection interface
- The possibility of adjusting on site by 15mm inall directions
- Connection and disconnection is achievedwithin an hour at most proving optimum
continuity of service.

The transformers are equipped withprovisions for safe handling.
Lifting with slings (figure 1)
Lifting is carried out using the 4 lifting holes
for a transformer without an enclosure and by
2 lifting lugs in the case of a transformer withan enclosure. The slings should not form an
inside angle greater than 600.
Lifting with a fork lift truck (figure 1&2)
The lifting capacity of the fork lift truck should
first be checked. If suitable, the forks should be
inserted inside the base channels after
removing the rollers.
Towing
Towing the transformer with or without
enclosure should be done from the underbase.For this purpose hole of 27 mm. Diameter are
provided on every side of the
underbase.Towing can be done in two
directions: in the axis of the underbase and
perpendicular to that axis.
Fitting the rollers
Either by lifting with slings (figure 1)
or by lifting with a fork lift truck (figures1 and 2)
In this case position the lifting forks in theunderbase channels.
- Place timbers of greater height than therollers under the channels and lower the
transformer on to them.
- Position jacks and remove the timbers.- Attach the rollers in the desired position
(bidirectional rollers).
- Lower and remove allowing the transfomerto rest on its rollers.

The transformer should be protected in
storage from water drops and dust
generating work (masonry, sanding etc). If
the transformer is delivered with a plastic
cover which should be kept over the
equipment whilst it is in storage.
The transformer can be stored at a
temperature down to 250C.

Check points when installing a castresin transformer
Installing conditions : installing place must be
clean and free from care of submersion under
water, especially not exposed water drops from
a ceiling of it. There must be a ventilation
means for getting rid of the heat generated
from a transformer.
Check of a transformer being taken custody for
long term : When dusts are deposited on a
transformer according to long term custody,
eliminate dusts by a vacuum cleaner or blow
away dusts by compressor, and wipe it by a dry
duster.
A vinyl package for preventing from inserting
of dusts, screws, nuts, washers and etc, must be
maintained until power is on after installation.

Check points before receiving power
Get rid of a vinyl package, and check
connection status, insulating separation,
distance, whether alien substances remain,
whether a component is damaged, and bolt
torque.
Check whether tap connections accord with
that of a label.

When measuring values are below than above
values, check humidity, and if it is, get rid of
humidity by dryer, and measure an insulation
resistance again. Nevertheless if a measured
insulation resistance is below than the limit
value, contact with the A/S (after-sale service)
department.
