Power Transformers for Ukraine’s Distribution & Substation Projects
Explore transformer options for Ukraine’s 10kV, 20kV and 35kV distribution networks, as well as higher-voltage substation applications. DHDL supports project-specific technical reviews for voltage ratio, rated capacity, cooling, installation conditions and documentation.

Understanding Ukraine’s Voltage Requirements
Ukraine’s electricity network spans medium-voltage distribution and higher-voltage transmission infrastructure. Actual transformer selection depends on the local utility connection point, the site’s electrical design and the purchaser’s technical specification—not the country name alone.
6 / 10 / 20 / 35 kV
Voltage levels relevant to distribution infrastructure and local network interfaces. Confirm the nominal voltage used by the specific distribution system operator.
110 / 150 kV
Relevant higher-voltage connections and step-down substations. Equipment ratings and winding arrangements must follow the project single-line diagram.
220 / 330 / 750 kV
These levels exist in Ukraine’s transmission network. Their inclusion here is grid context, not a claim that DHDL supplies every rating.
Typical Voltage Combinations to Review
The combinations below appear in Ukraine energy-equipment needs documents or reflect network levels used in the country. They are planning references—not universal national specifications and not confirmed DHDL stock models.
| Grid / project context | Reference voltage | Potential transformer use | Procurement check |
|---|---|---|---|
| Local distribution | 10kV / 20kV | Medium- to low-voltage distribution transformers | Confirm LV output, kVA, insulation and network operator requirements |
| Regional distribution | 35/10kV; 35/6kV | Step-down transformers at distribution substations | Confirm MVA rating, tap regulation and protection interface |
| Higher-voltage substations | 110/35/10kV | Multi-winding / substation transformer projects | Confirm winding arrangement and utility specification |
| Regional substations | 150/35/10kV | High-voltage step-down transformer projects | Verify project location, operator and required standard |
| Bulk network | 330kV / 750kV | Transmission and large autotransformer context | Project-specific technical and manufacturing feasibility review |
Note: Nominal grid voltage is not the same as maximum equipment voltage or a transformer’s complete winding ratio. Verify equipment details against drawings and tender requirements.
Transformer Types for Ukraine-Focused Projects
Rather than recommending one generic model for the whole country, the following categories provide starting points for technical evaluation.
Oil-Immersed Distribution Transformers
For outdoor distribution and utility or industrial power distribution projects where oil-filled construction is suitable.
Explore product range →Dry-Type Distribution Transformers
For indoor load centres, buildings and facilities with specific installation and fire-safety considerations.
Explore product range →Substation Power Transformers
For higher-voltage transformation applications that require engineering review of capacity, winding arrangement and cooling.
Discuss specifications →Final product availability, voltage ratings and compliance documentation must be confirmed by DHDL for each project.
What Buyers Should Confirm Before Ordering
01. Voltage & Winding Ratio
Specify nominal HV/LV voltages, number of windings, tapping range and off-circuit or on-load tap changer requirements.
02. Capacity & Load Profile
Provide kVA/MVA demand, load cycle, expected overloads, losses and future expansion assumptions.
03. Installation Conditions
State indoor/outdoor installation, ambient temperature, altitude, space constraints and cooling preferences.
04. Grid Frequency & Connection
Confirm 50Hz, vector group, neutral grounding, short-circuit impedance and the point of interconnection.
05. Standards & Testing
Supply the applicable tender standard, inspection plan, loss limits and factory acceptance testing documents.
06. Shipping & Project Scope
Clarify destination, delivery terms, transport constraints, packaging and any commissioning support required.
Where These Transformer Solutions May Be Used
Distribution Network Upgrades
Replacement or additional transformer capacity at local distribution nodes, subject to utility specifications.
Factories & Industrial Facilities
Transformer selection for industrial incoming power, equipment loads and site expansion.
Substation & Infrastructure Projects
Engineering-led transformer specification for higher-capacity substations and infrastructure facilities.
From Specification Review to Transformer Manufacturing
DHDL provides a range of transformer and power distribution equipment. For overseas projects, our role begins with understanding the required voltage, loading conditions, installation environment and technical documentation.
For Ukraine-related enquiries, we recommend sending the project single-line diagram and technical specification before choosing a transformer model.

What transformer voltage levels are relevant to Ukraine?
Ukraine uses several distribution and higher-voltage network levels. 10kV and 35kV are common reference points; 20kV can be relevant to specific distribution projects, while 110kV and 150kV appear in substation applications. The actual transformer winding ratio must be taken from the project documentation.
Can a 35/10kV transformer be considered for a Ukrainian substation?
35/10kV is a configuration cited in Ukrainian energy equipment requirements. Whether it is suitable depends on rated MVA, winding design, impedance, tap range, protection and local utility approvals.
Does Ukraine use 50Hz electricity?
Yes, Ukraine’s AC grid frequency is 50Hz. A tender may also specify acceptable frequency tolerances and related performance requirements.
Are oil-immersed or dry-type transformers more suitable?
Oil-immersed units are commonly considered for outdoor distribution and substation applications, whereas dry-type units can suit indoor buildings and industrial load centres. Selection depends on site conditions, fire considerations and project specifications.
What information is needed for a transformer quotation?
Send the project location, HV/LV voltage, rated capacity, frequency, vector group, impedance, cooling method, quantity, required standards, delivery destination and any tender or single-line drawing.
Does DHDL supply every transformer voltage used in Ukraine?
No blanket compatibility claim should be made. DHDL needs to review the specified rating and project requirements to confirm manufacturing feasibility, testing and documentation before quoting.
