Introduction:
Load regulating power transformer is developed and produced according to the requirement of the market. It
can be widely used in urban & rural, industrial & agricultural power network, which has a great significance for
energy-saving and environment protection. The lamination method of this product's iron core is ladder form,
instead of the traditional iron core lamination technology, which improves the magnetic circuit distribution inside
the iron core. It can be seen as a revolution of transformer iron core manufacturing. Compared with the
traditional, the no-load loss, no-load current and noise of the new one decrease 20% respectively, and load
loss decreases 10%. The new product applies CAD, with advance design, reasonable structure, and excellent
materials. Each index complies with the standards of GB1094-1996 "Power Transformer" GB/T6451-1999
"Technical Parameters and Requirements of Three-phase Oil-immersed Type Power Transformer". Now its level
is the leading position of our country.
Features:
High reliability, advanced level of performance, economic indicators and reasonable;
Using phase-shaped core of three joints, curing paint brushing the surface to reduce wear and tear and noise;
Winding structure of a new oil road design is reasonable, with the new insulation to improve the mechanical
strength and the ability to engage in short-circuit;
Tank forms, beautiful, generous.
Technical parameters:
Product model: DH15-M or D11-M
Rated Voltage:10kV/(0.22~0.24) or 2×(0.22~0.24) kV (or the voltage proposed by the user)
Tapping range: ±5%; ±2*2.5%
Frequency: 50Hz
Vector group: II0 or II6
Operation environment: outdoor
In order to meet the various demands of customers, the Company has design D11-M and DH15-M two series
single phase fully-sealed transformer. D11-M transformer adopts laminated core and is characterized by low
loss, low noise level and others; DH15-M transformer adopts amorphous alloy core which further reduces the
no-load losses of the transformer. Table below specifies technical parameters and dimensions of the two series
of transformers.
