Transformer & Power Distribution

Turnkey substations, distribution transformers, MDB/DB, PFI & busbar trunking — engineered, installed, and commissioned with utility approvals and full compliance documentation.

Reliable Power—from Grid to Machine

AAEL designs and delivers HT/LT power distribution systems for industrial, commercial, and institutional facilities. We plan protection coordination, cable sizing, and layouts, then supply, install, test, and commission the entire system with clear as-builts and test sheets. Our team coordinates closely with DESCO/DPDC/REB for energization and inspection.

What We Specialize In

Substations & Transformers

Distribution substations with oil/dry transformers, RMU/Switchgear, NGR/earthing, and interlocks for safe operation.

LV Distribution

MDB, SMDB, DB, PFI, ATS/AMF, capacitor banks, power panels, and metering — factory-tested and labeled.

Busbar & Cable Systems

Al/Cu cables, ladder/tray routing, and BBT (feeder/plug-in) with thermal, short-circuit, and voltage-drop checks.

Our Turnkey Scope

Substation design & layout (HT/LT), SLD & load schedule
Transformer, RMU/LBS/VCB, HT/LT switchgear selection
MDB/SMDB/DB, PFI, ATS/AMF, metering & protection
Busbar trunking (feeder/plug-in) & cable routing
Earthing/bonding, lightning interface & SPD coordination
Testing, commissioning & utility inspection support

We plan for maintainability, arc-flash risk reduction, and clear labeling for operators and auditors.

Standards & Guidelines

Designs and panels reference these codes and practices:

BNBC IEC / BS IEEE NETA / ANSI (testing) DESCO / DPDC / REB

Handover Documents

As-built drawings (SLD, layout, routing)
Test reports (IR, continuity, injection, relay settings)
Equipment datasheets & factory certificates
Utility inspection notes & energization approval

Frequently Asked Questions

We size based on diversified demand (kVA), future growth, utility constraints, and voltage drop. We also verify short-circuit withstand and losses (IEC/BS).

Yes. We coordinate upstream/downstream breakers and relay settings to achieve selective tripping and safe fault clearing times.

Absolutely. We prepare drawings, testing records, and arrange inspections for DESCO/DPDC/REB until energization.
