Understanding Myanmar’s Distribution Voltage Levels
Myanmar’s distribution network includes several medium- and low-voltage levels. For transformer buyers, 11kV and 33kV are particularly relevant to distribution substations, industrial connections and local network projects. Final transformer ratings must always follow the actual utility connection and project drawings.
33 kV
Widely documented in Myanmar’s distribution network and used for regional feeders, substations and higher-capacity distribution connections.
11 kV
A major local distribution level used for feeders, industrial supply and step-down transformation toward low-voltage networks.
6.6 / 66 / 230 kV
Other documented voltage levels exist in Myanmar’s distribution and transmission systems. Their relevance depends on location, utility and project connection point.
Voltage Levels and Transformer Specification Considerations
Use the following values as an initial network reference. Nominal grid voltage, transformer winding voltage, highest voltage for equipment and insulation level are separate design parameters and should be confirmed from project specifications.
| Grid context | Reference voltage | Transformer evaluation | Technical reminder |
|---|---|---|---|
| Medium-voltage distribution | 11 kV | Distribution transformers serving local and industrial loads | Confirm actual HV/LV winding ratio and tapping requirements |
| Primary distribution | 33 kV | Distribution and substation transformer applications | Confirm insulation level, protection and utility interface |
| Distribution substation | 33 / 11 kV | Step-down transformer applications between distribution levels | Capacity, impedance and winding configuration require project review |
| Local distribution | 11 / 0.4 kV | Distribution transformers supplying low-voltage networks | Confirm 400/230V network requirements and load characteristics |
| Transmission / sub-transmission context | 66 / 230 kV | Project-specific power transformer review | Grid presence does not imply DHDL availability for every rating |

Transformer Categories for Myanmar-Focused Projects
Begin with the actual application and electrical specification, then select the construction, capacity and voltage configuration appropriate to the project.
Oil-Immersed Distribution Transformers
Suitable for utility distribution, industrial sites and outdoor applications where oil-filled transformer construction is appropriate.
Explore transformers →Dry-Type Transformers
For indoor industrial, commercial and infrastructure applications where fire safety, installation environment or maintenance requirements favor dry-type construction.
Explore transformers →Substation Power Transformers
For 33/11kV and other project-specific substation applications, subject to transformer capacity, winding arrangement and manufacturing capability review.
Discuss a specification →What Buyers Should Confirm Before Selecting a Transformer
01. HV/LV Voltage Ratio
Confirm whether the project requires 33/11kV, 11/0.4kV or another winding ratio, together with tapping range and utility interface.
02. Rated Capacity
Specify kVA or MVA rating, expected load profile, peak demand, future expansion allowance and transformer loading conditions.
03. Site Conditions
Provide installation altitude, ambient temperature, humidity, rainfall, ventilation, dust exposure and indoor or outdoor installation conditions.
04. Electrical Coordination
Confirm 50Hz frequency, vector group, impedance, neutral arrangement, short-circuit requirements and protection coordination.
05. Standards & Testing
Share governing IEC requirements, utility specifications, loss limits, inspection requirements and project acceptance tests.
06. Logistics & Documentation
Confirm destination, packing requirements, technical drawings, test reports, accessories, spare parts and delivery scope.
Applications Across Myanmar’s Power Distribution Network
Utility Distribution Networks
11kV and 33kV transformer configurations for local distribution, feeder reinforcement and utility substation projects.
Industrial & Manufacturing Facilities
Transformers for factory incoming power, industrial machinery, process loads and facility capacity expansion.
Substation & Infrastructure Projects
Technical specification review for substations, infrastructure, commercial developments and other higher-capacity power projects.
Specification Review, Manufacturing & Quality Control
DHDL supplies transformers and power distribution equipment for utility, industrial and infrastructure applications. We begin with the buyer’s electrical drawings, operating requirements and acceptance criteria to identify technically suitable options.
For Myanmar projects, buyers should specify the actual 11kV or 33kV connection requirements and transformer nameplate values instead of relying only on a general national voltage reference.

Which distribution voltages are commonly used in Myanmar?
Myanmar power-system documentation includes 33kV, 11kV, 6.6kV and 0.4kV distribution levels. For many transformer projects, 11kV and 33kV are important reference voltages, but the actual project connection must be confirmed with the utility or tender documents.
Is an 11kV transformer suitable for every Myanmar project?
No. The required transformer depends on the actual grid connection, secondary voltage, capacity, insulation level, impedance, loading conditions and application. Some projects may require 33kV incoming supply or other voltage configurations.
Are 33/11kV substations used in Myanmar?
Yes. 33/11kV substations are documented in Myanmar’s distribution network and electrification projects. The required transformer capacity and configuration still depend on the individual project.
What low-voltage supply is used in Myanmar distribution networks?
Myanmar power-sector documentation describes 400/230V, three-phase four-wire low-voltage networks with a nominal system frequency of 50Hz.
What information should I send for a transformer quotation?
Provide the single-line diagram, HV/LV voltages, transformer capacity, quantity, frequency, vector group, tapping range, impedance, site conditions and required standards or tests.
Can DHDL supply customized transformers for Myanmar projects?
DHDL can review project-specific transformer requirements and discuss suitable configurations. Final feasibility, technical compliance, manufacturing scope and quotation require engineering confirmation.
