6.6 kV - 315kVA Cast Resin Dry Type Transformer , Three Phases , Two Winding , Power Distribution
Product 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.
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 recycling.
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.

Tests shall be done in conformity referring to the manufacture standard.
All tests procedure shall be in accordance with referring standard (IEC or ANSI). 6-1 Design tests (type tests) :
A type test report in accordance to referring standard must be presented with offer. 6-2 Routine test:All routine tests must be performed by manufacture, results must be send to the purchaser before the date of acceptance test (in case of signature of contract).
1.Acceptance tests : Inspections & Tests at Contractor’s Premises
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 equipment:
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.
