HT power distribution design
Substation layouts, transformer sizing, overhead and underground cabling, and protection schemes up to 33 kV and 11 kV.
Energy & Power
Electrical engineering — HT & LT
DMC provides high-voltage and low-voltage electrical engineering: HT distribution design up to 33 kV and 11 kV including substation layouts, transformer sizing, cabling and protection schemes; LT distribution networks with main distribution boards, wiring, lighting and earthing; plus load and fault-level analysis, single-line diagrams, regulatory approvals and site supervision. Designs comply with IEC and IEEE standards.
We are an electrical engineering consultancy specialising in high-voltage (HT) and low-voltage (LT) infrastructure. Our work sits at the point where complex engineering meets operational reality: robust design, meticulous planning, and rigorous site supervision that together make power systems safe, efficient and capable of carrying tomorrow's load.
Core capabilities
LT distribution networks
Main distribution boards (MDBs), internal wiring, lighting layout, earthing systems and smart energy management.
Technical supervision and quality control
Real-time site inspection, contractor management, equipment testing and pre-commissioning audits.
Feasibility and compliance
Load calculations, fault-level analysis, single-line diagrams (SLDs), and local regulatory approvals.
Design
We engineer scalable power infrastructure. From high-voltage grid connections to low-voltage internal distribution, our designs optimise energy efficiency and system reliability — and are sized for the load the facility will actually carry once it is fully occupied, not the load in the brief.
Supervision
Blueprints only work if they are executed properly. Our engineers provide on-site supervision to guarantee that materials, installation techniques and safety protocols match what was specified — because the failure modes that matter most are almost never design errors. They are substitutions, shortcuts and untested terminations.
Standards
IEC — International Electrotechnical Commission
All HT and LT designs comply with IEC standards, meeting international benchmarks for equipment safety, efficiency and performance.
IEEE — Institute of Electrical and Electronics Engineers
We apply IEEE guidelines for advanced system modelling, fault analysis and protection coordination studies.

Common questions
Frequently asked questions
What voltage range does DMC cover for distribution design?
HT distribution up to 33 kV and 11 kV, and the full range of LT internal distribution — main distribution boards, wiring, lighting layout, earthing and energy management.
Which standards do DMC electrical designs follow?
IEC standards for equipment safety, efficiency and performance, and IEEE guidelines for system modelling, fault analysis and protection coordination studies, alongside local regulatory requirements.
Does DMC supervise electrical installation on site?
Yes. Site inspection, contractor management, equipment testing and pre-commissioning audits are offered, because most electrical failures originate in substitutions, shortcuts and untested terminations rather than in the design.
