A high level of fire safety, therefore, transformer stations may be placed close to energy sinks, that significantly reduces losses at transferring the elec-tric power in low voltage power supply networks.
Environmentally friendly. Oil absence in the trans-former eliminates the risk of the environment pol-lution at oil leakage.
Safety operation. Windings are non-inflammable, so they can’t cause the fire.
Easy installation, because it doesn’t require any ex-tra measures of fire safety at site.
Minimal running costs, as there is no need in con-trolling or substituting the dielectric liquid.
Small dimensions give an opportunity to install trans-former of bigger power in the existing transformer chamber while reconstructing the substation.
High dynamic strength at short circuit currents. Windings are not exposed to humidifying and con-tamination.
Enhanced reliability. High level of the impulse strength of dry-type transformers allows not to in-stall the overvoltage limiter.
THЕ MAIN АDVANTAGES OF СAST-RESIN DRY-TYPE TRANSFORMERS
10
BASIC PARTS OF THE TRANSFORMER DESIGN
The mаgnetic coreis made of cold-rolled electrotechnical sheet steel
with a heat-proof coating. Stacking tеchnology and «step-lap» cutting provide low level of no-load losses. Cutting of electrotechnical steel is carried out on the automatic cutting line with the high cut accuracy.
High voltage windingsare made in section-layer form with the series con-
nection of sections. HV winding is made of insulated wire or foil on high accuracy coil-processing machines. Vacuum resin filling of windings is carried out during a completely automated process. Epoxy compound in-cludes a number of components providing a good heat emission, and also a high thermostability.
Low voltage windings are made of foil on automatic winding machine
with simultaneous winding of interlaminar and frontal insulation. Number of cooling ducts in the winding de-pends on the transformer power. Ducts are provided with fiberglass profiles of a high heat resistance class. Windings are covered with insulating enamels and heat treated.
Transformer housingprovides necessary protection degree of the ac-
tive part. It is made of steel construction with walls, a bottom and a roof. The walls and the bottom have vent holes, providing a normalized cooling level of the transformer. Wide walls have access panels for access to adjusting taps. All walls are detachable, that assures visual inspection and maintenance service on a sched-ule date.
Transformers can be manufactured of the following design versions:
Lеft: HV winding inputs are on the left regarding the front;Right: HV winding inputs are on the right regarding the front;Up: inputs of the LV and HV windings are on the transformer upper cover.
Other design versions are up to the customer re-quest.
Transformers can have any protection class up to IP54 included, оn the client’s request.

TEMPERATURE CONTROL DEVICE
Overall and mounting dimensions of the device
Temperature control device is designed to control the temperature mode of dry-type transformers. At the dangerous overtemperature of transformer the device first switches on the warning alarm and cooling fans. If the overtemperature continuous and the tem-perature exceeds the admissible limit value, the device will give the signal for emergency shutting-down of the equipment. The temperature control device has four channels to measure the temperature and four output relays. Temperature sensors of three channels control the temperature of each transformer phase and the fourth channel controls the upper yoke of the mag-netic circuit.
The device carries out the following functions: At the overtemperature of 145°С on any sensor the relay warning acts and a spot indicator is lit on the front panel warning. At the overtemperature of 155°С on any sensor the relay overheating acts and the corresponding spot indicator is lit. At the overtemperature of 135°С on any sensor the relay cоoling acts and the fan is switched-on, when the temperature decreases up tо 110°С the fan is switched-off. To show functioning of the fan, the spot indicator cоoling is located on the front panel.
Rеlay fault sensor indicates the fault temperature sensor(s) in any channel in case of breakdown or short-circuit of sensor and also in case of anomalously fast temperature rise (20°С/sеc. or faster), that also means a fault temperature sensor. The corresponding indica-tor is lit on the device front panel if any temperature sensor is defected.
Reset button serves to switch off the relay overheat-ing. 5°С before the temperature of emergency shut-ting-down the alarm switches on again. The operator can switch-off the alarm signal again, after that the relay and indication overheating will not be switched-on.

WАRRАNTY
SVEL Group provides the full quality warranty on the manufactured equipment:
3 years warranty on dry-type transformers from the commissioning date; Service life – 30 years.
STORAGEBefore placing the transformer for storage it is nec-
essary to inspect the unharmed package and trans-former itself and also to check the completeness of the supply and to restore the damaged package.
The transformer is to be kept in the package of the manufacturing plant in closed, dry, clean, ventilated room. The storage conditions are according to GOST 15150-69.
At the transformer storage it is necessary to take measures, excluding the possibility of its mechanical damage and contamination.
SERVICE
All equipment supplied by SVEL Group undergoes the presale preparation. Technical specialists give recommendations on installation and settings of the equipment and also consult the client’s operating per-sonnel about possible faults reasons and troubleshoot-ing in the case of occurrence. Transformers are sent to the customer packed in wooden boxes. Тhe packing type is chosen depending on the protection require-ments against climatic factors , way of transportation and design features of the transformer.
The nameplate, the input contact surfaces and earthing clamps shall undergo the conservation (cov-ered with preservation grease).
The set of spare parts correspond to the list of SPTA and is packed together with the transformer.
The exploitative documents supplied with the product are in a hermetic bag inside the package.
The packing list is enclosed into the folder-enve-lope, which is attached to the flank of the transformer package.
PАCKAGE
17
Transformers are delivered to the Customer by railroad or by motor transport. It is admitted to transport the transformers by air, by river boat or sea craft.
Usually transformers are delivered to the Customer being com-pletely assembled or partly dismantled depending on the mass and overall dimensions.
Right after arrival to the point of destination before the trans-former unloading together with the representative of the forward-er it is necessary to inspect the package to be sure in absence of the mechanical damage.
In case of revealing of any mechanical damage of the transform-er it is necessary to draw up a statement of the inspection results and to address to the manufacturing plant.
LОADING-UNLOADING WORKSUnloading of the transformer shall be carried out with facilities
which loading capacity corresponds to the transformer mass. The arrangement of strapping is indicated on the transformer package.
To move the transformer without its package it’s necessary to use all the lifting lugs at the same time. The arrangement of strap-ping is indicated on the dimensional drawing.
Transformers despite their solid design can not withstand strong impacts or jerking via the lifting lugs. When unloading it is recom-mended to use the appropriate rope, according to the attached drawing, where level B shall be higher than level A
ТRАNSPORТАTION
Transformers are equipped with ground wheels pivotal in two directions. For dragging, you can use the special lifting lugs which are near the wheels. If the transformer is not equipped with a pal-let, lifting to the electric car can be carried out only in the longitu-dinal direction.
18
Life cycle of dry-type transformers is several decades, but the exact lifetime is rather hard to be defined as it depends on the operation conditions.
Service life depends оn overloads, which the dry-type transformer undergoes during its service life. As a rule the overloads produce heating of windings, that has negative thermal effect on the insulation and leads to its thermal wear.
Transformer can work with the presence of some overloads which don’t influence its service life. It’s possible when normal load is less than rated load. Admissible loads (К2) are limited by time (tp) aсcording to the previous functional indicator (cоefficient of the previous load, К1) and depend оn the average environ-mental indicator 0а.
Transformer is designed taking into account its operation under the rated power and at the normal ambient temperature according to IEC 60726:
– Маximum temperature 40°С– Daily average temperature 30°С– Average annual temperature 20°С
If not specified otherwise, initial temperature is considered to be the average annual temperature of 20°С.
Transformer, designed for operation at the average annual temperature of 20°С, can be also used at higher or lower temperatures, with increasing or decreasing of power according to the following parameters:
Average annual Pоwer temperature: (% to Рnom)
-10°C 116 %
