Three Phase Cast Resin Dry Type Transformer For Powe Transmission
Cast Resin Dry Type Transformer Utility :
With excellent performers, it can overcome those harsh operation
conditions: high altitude, high humidity, high temperature and
large temperature difference.
In daily life, it is exactly suitable for the places like
government offices and bureau residential area and other areas that
strictly demand of special require for fire proof.
Rising the challenge of large load fluctuation or long time
overload places, it can be widely used in some places, for
instance, urban rail, metallurgical industries, power plants,
shopping mall and so on.
Cast Resin Dry Type Transformer Characteristics:
It has effect of cooling capacity and high performance such as
moisture proof and light shock resistance.
It meets the needs of environmental adaptability and lighting
shocks, strong resistance to thermal shock, anti-cracking and
It adopts NOMEX insulation systems in the main insulation,
inflaming retarding, explosion proof and so on.
Vacuum pressure impregnation curing process, high mechanical
strength, withstand short-circuit, safe and reliable.
Cast Resin Dry Type Transformer, Low Noise, Low Loss and Low Partial Discharge.

1.Acceptance tests : Inspections & Tests at Contractor’s
All materials and equipment used in the Facilities may be inspected
by the purchaser at any time.
All equipment shall be subjected to all routine tests set out in
relevant IEC standards, including any optional tests which the
Project Manager deems to be applicable.
One item of each type of plant shall be subjected to all type tests
set out in relevant IEC standards. Such tests may be waived in
cases where the supplier submits reports of type tests conducted by
third- party testing agencies and which are accepted by the Project
Manager as adequately demonstrating that the equipment complies
with the relevant IEC requirements.
Mandatory factory acceptance tests (FAT) shall be performed for all
The Contractor should allow for one (1) trip for each set of
equipment. Factory test reports shall include current calibration
records of all measuring apparatus used in the tests.
No equipment shall be despatched from the factory to site prior to
receiving the client / Project manager notification that the
factory tests were satisfactory. The Purchaser may request that
additional tests be conducted if he is not satisfied that the
factory tests have demonstrated that the plant is acceptable.
The Contractor shall provide two (2) representatives of the
purchaser and the one (1) from the supervision firm, to attend each
factory test. The Contractor shall meet all associated travel,
accommodation and living costs, which shall be deemed to be
included in the Contract Price.
