Basic Info.
Product Description
It is suitable for power systems of AC50Hz and rated working voltage up to and including 10kV,can be used as distribution transformer for petroleum,metallurgy ,chemical industry ,textile industry ,light industry,etc.
The iron core is made of cold-rolled grain-oriented silicon steel sheets with high magnetic conductivity,with inclined joint laminated structure.section of the core limbs is of multi-class ladder round,with uniform section with that of yoke.
The winding adopts corrugated oil duct with non-dipping process,bound by shrinkable tape;all winding are of concentric coils;taps of HV winding with corresponding tapping voltage shall be led to the tape switch,and the switch shall be installed on the box cover.Power supply must be cut off first when changing the tapping voltage.
Service conditions
1.Installation height: altitude shall not exceed 1000m
2.Ambient temperature:-40ºC~40ºC
