Testing & Services

We have professional technical staff.Online guidance,Forming the largest assistance network.


Regular Tests

+Voltage ratio measurement +Applied withstand voltage test +Induced withstand voltage test +Partial discharge measurement +No load loss and current measurement +Winding resistances measurement +Insulation resistance test +Load loss and short circuit impedance measurement +Transformer oil test

Type Tests

On customer requirements +Temperature rise test + Lightning impulse test + Noise level test

Special Tests

On customers'requirements, below parameters can be checked +Zero-sequence impedance +No-load voltage harmonic + Parallel capacity of windings +Anti-corrosion protection checking +Short circuit test


+In the warehouse, transformer should be protected from the pollution of water droplets, dust and sand.If provided with plastic cover, the transformer should be covered during storage.

Technical support and scheme design

Shipment Service


+The transformer is equipped with safety transport devices.The transformer without shellshall be lifted with lifting lugs, the medium and small dry transformers with shellshall be lifted with lifting rings, and the large transformershall be lifted with special lifting device for foundation channel steel.


+The product is ready for shipping either by truck or seafreight once it has passed the tests.We take care of all official docu-ments,depending on destinations and delivery terms.We also provide different packaging for special applications or conditions

Team Work

Warrantly and Technical Assistance


+We supply the installation guide and user manual for each transformer.Under normal conditions,check the transformer once a year and clear the dust by vacuum cleaner.The frequency of cleaning depends on the running conditions.


+When some parts need to be replaced or any information is required,the main parameters on the nameplate must be provided, especially the serial number.We provide stock in regular quantities of spare parts, in case of customer needs.
