Transformer substations up to 35 kV
MV intake, RMU and switching interfaces, transformer installation, LV tie-ins, utility coordination and energisation readiness.
QuangAnhcons · Industrial Electrical & Energy Infrastructure · Vietnam
Reliable power infrastructure starts with a well-defined electrical scope.
QuangAnhcons supports industrial MV/LV electrical construction, transformer substations up to 35 kV, factory power upgrades and integration of rooftop solar and EV charging infrastructure in Vietnam.
For factory owners, developers, international investors and main contractors. Engineering decisions, technical specifications and work boundaries are confirmed for each project.
Electrical packages with defined boundaries
From the utility interface through MV/LV distribution and equipment connections.
Delivery informed by site conditions
Construction access, safe workfronts, coordination and quality records matter.
Clear technical and commercial assumptions
BOQ basis, equipment data, exclusions and acceptance requirements are reviewed early.
Electrical infrastructure for modern industrial facilities.
Our scope is centred on the power systems that keep industrial facilities operating. We work with approved designs and coordinate technical interfaces with employers, designers, suppliers and utilities as agreed.
Industrial MV/LV electrical works
Power distribution, MSB/MDB, cable routing and terminations, industrial feeders, earthing and electrical handover documentation.
Rooftop solar electrical BoP
Practical PV site and grid-interface checks, inverter integration, AC/DC distribution, protection and construction coordination.
EV charging power systems
Charging demand and spare-capacity review, transformer and LV upgrades, distribution, metering and charger vendor interfaces.
Power upgrades & modernisation
Capacity expansion, transformer replacement, MV/LV refurbishment, outages and constructability planning for operating factories.
Site surveys, BOQ & tender support
Electrical scope definition, site observations, quantity take-offs, constructability, technical submissions and interface registers.
Who we work with
Built for industrial project teams and their real constraints.
Power infrastructure often sits on the critical path between construction completion and factory operation. We focus on the documentation, interfaces and construction requirements needed to turn a technical scope into an executable work package.
Typical project stakeholders
- FDI manufacturers and Vietnamese industrial enterprises.
- Factory owners and plant engineering teams.
- Industrial developers, warehouses and logistics operators.
- General contractors and specialist EPC project teams.

Examples describe previous capacity classes, not a warranty of project performance or evidence that nearby general site images belong to these specific contracts.
From enquiry to energisation, with fewer scope surprises.
We aim to identify technical gaps early, keep the interface matrix transparent and distinguish preliminary budgets from quotations supported by validated drawings and site conditions.
01 / UnderstandReview the site and requirements
Power demand, utility point, site layout, operations, target date and available drawings.
02 / DefineAgree technical boundaries
Confirm BOQ basis, equipment selection, design ownership, exclusions and responsibilities.
03 / ExecuteCoordinate workfronts
Material submittals, site access, installation sequence, safe isolation and inspections.
04 / VerifyTest and hand over
Specified testing, punch-list closure, as-built documents and utility/vendor coordination.
Site experience, documented with real work.
Photographs from the website media archive illustrate the installation environment and the kind of site coordination involved. We do not substitute AI-generated scenes for verified client-project evidence.
EV charging, rooftop PV and BESS require coordinated electrical interfaces.
The right electrical architecture depends on existing transformer capacity, feeder ratings, consumption profile, protection, operating duty and utility conditions. Adding equipment without revisiting these interfaces can lead to avoidable redesign and costs.
QuangAnhcons can discuss early-stage sizing questions and electrical tie-in requirements. Detailed BESS design, fire safety, equipment certification and specialised commissioning responsibilities must be explicitly allocated to suitably qualified parties.
Before requesting a budget estimate
- Confirm existing transformer kVA, MV/LV drawings and spare capacity.
- State expected solar DC kWp / AC kW or usable roof area.
- For BESS, distinguish power (kW) from usable energy (kWh) and duty cycle.
- For chargers, list charger kW, quantity and likely simultaneous demand.
- Identify grid connection and shutdown constraints.
Fast estimate tools are reserved for future integration. Indicative outputs are not approved designs or binding quotations.
Technical reading for industrial project decisions.
Practical commentary on MV/LV design responsibility, procurement, substations, factory power and new-energy electrical interfaces. Always check the relevant standard edition and project-specific conditions.
Useful questions
Before starting an electrical RFQ.
The quality of the first scope description determines how quickly key risks and missing inputs can be identified.
What information should a factory provide for a substation quotation?
Project location, estimated load, transformer capacity or SLD, medium-voltage intake arrangement, expected civil and electrical boundaries, preferred equipment, drawings and timeline.
Can we combine factory upgrades with rooftop solar or EV charging?
Yes. Each load and generation interface should be assessed together, especially for transformer capacity, protective devices, metering and operational constraints.
Does QuangAnhcons provide complete factory civil works or specialist HVAC installations?
Our primary offer is industrial electrical infrastructure. Any civil, mechanical, HVAC or specialist scope must be explicitly agreed and assigned to appropriately qualified parties; it is not implied in an electrical RFQ.
Is a preliminary estimate a fixed price or an approved technical design?
No. Budget estimates are subject to drawings, site survey, equipment quotations, project specifications, utility requirements and defined contractual assumptions.
