COMPANY PRODUCTION
Hengfengyou transformer Qingdao branch is one of the holding
subsidiaries of "Qingdao Hengfengyou group". It has been
specialized in the development research, manufacturing and service
of power transformers for 30 years. Our main products are: oil immersed transformer, dry type
transformer, amorphous alloy transformer, experimental transformer,
electric furnace transformer, rectifier transformer, etc. At
present, our 10kV, 12kV, 20kV, 33kV, 35kV oil immersed transformers
of S11, S13 series , 10kV, 12kV, 20kV, 33kV, 35kV epoxy cast
dry-type power transformers of SCB10, SCB13 series , SH15, SCBH15
amorphous alloy power transformers, on load tap changing
transformers and other products have passed the inspection of the
national electrical product quality supervision and inspection
agency and obtained the registration model record certificate. The
products also passed the energy efficiency product certification of
China quality certification agency, CCC product certification of
national power certification agency, EU CE certification, ISO9001
quality management system certification and so on.
33KV oil immersed transformer
33kV series oil immersed power transformer is advanced in design,
and greatly improved in material, structure and technology. Showing
strong short-circuit resistance, beautiful appearance, reliable
operation, low loss and low noise, it’s performance reaches the
advanced level of global similar products.
35 KV oil immersed transformer
Compared with S9 series, the no-load loss of S11 series products is
reduced by 30% on average, and no-load current is 70-80% lower. The
iron core is made of import high magnetic conductivity, low loss,
cold-rolled high-quality silicon steel sheet, which reduces the
no-load loss and saves energy significantly. It shows
characteristics of high safety and reliability, advanced structure,
small dimension, light weight, low noise, low temperature rise,
anti-corrosion and reliable anti-leakage measures to prevent oil
leakage.
Note: Due to continuous product improvement, the dimensions provided in
this sample are for reference only. If necessary, our company can
design and produce according to user requirements. Please contact
the company in time.
