Overview
General Product Overview
The 33/35 kV oil-immersed transformer serves higher-voltage distribution and collector systems. Its winding design, cooling arrangement, tap range, cable interface and impedance are confirmed against the network voltage, load profile and installation conditions.
Main Technical Specifications
Parameter |
Typical range / configuration basis |
Rated voltage |
33 kV or 35 kV class |
Rated capacity |
500-20,000 kVA |
Frequency |
50 Hz or 60 Hz; utility-specific where applicable |
Standards basis |
IEC 60076 |

Core Technology and Efficiency Options
The design can be optimized around total ownership cost rather than nameplate rating alone. Conductor selection, core material, flux density, tank construction and cooling surface are coordinated to meet the agreed no-load loss, load loss, temperature-rise and sound requirements.
Main Applications
Renewable step-up systems, industrial substations and regional distribution networks.
Engineering Support
Apex supports requirement review, product selection, drawing and interface coordination, manufacturing follow-up, inspection/test-document coordination, export packing and delivery planning. The final scope is defined in the quotation and approved technical agreement.
