PRODUCT CATEGORY 02
LV Switchboards & Distribution Equipment
Low voltage switchboards designed to IEC 61439-1 and -2, with full type-test documentation. We supply main distribution boards, sub-distribution boards, motor control centers, and power factor correction panels for new builds and retrofit projects.
Main Distribution Boards (MDB)
LV MDBs for transformer secondary distribution. Rated per IEC 61439-2. Bus-coupler configurations available for critical facilities requiring N+1 redundancy. Metering to MID
Sub Distribution Boards (SDB)
Floor-level distribution boards for commercial and industrial tenant distribution. Short-circuit and protective device coordination calculations provided as a design deliverable on every project.
Motor Control Centers (MCC)
Fixed and draw-out MCCs with DOL, soft-starter, and variable frequency drive (VFD) configurations. Full loop testing and interlock verification performed at commissioning.
Power Factor Correction Panels
Automatic capacitor bank panels sized from site load profile data. Harmonic-filtered variants (detuned reactors) available for non-linear load environments to prevent resonance.

PRODUCT CATEGORY 03
Distribution Transformers
We supply distribution transformers from verified manufacturers with full factory test reports (FTR). Transformer sizing is calculated from site load schedules. All units are commissioned with insulation resistance, turns ratio, and magnetizing current tests prior to energization.
Oil-Immersed Transformers
ONAN/ONAF cooled distribution transformers from 25kVA to 2500kVA. Equipped with OILTAP or de-energized tap changers. Full factory test report mandatory on all units prior to dispatch acceptance.
Dry-Type Transformers
Cast resin and VPI dry-type transformers for indoor installations, data centers, and environments where oil is operationally or safety-prohibited. Available in Class F and Class H insulation systems.
Compact Substations
Packaged MV/LV substation units combining RMU, transformer, and LV switchboard in a single factory-assembled enclosure. Factory acceptance tested prior to site delivery, reducing site installation time.
Earthing Systems
HV/LV earthing grids designed to IEEE 80 and IEC 60364. Earth resistance testing and step/touch potential verification included as commissioning deliverables.

Protection & Control Systems
Protection relay selection, configuration, and coordination are executed by our protection engineers using site-specific short-circuit studies. All settings are verified by secondary injection testing prior to system energization. No protection system is handed over without a documented test record.
Protection Relays
Overcurrent (ANSI 50/51), earth fault (50N/51N), differential (87T/87B), distance (21), and auto-reclose relays. Settings documented in relay coordination reports and verified against protection study requirements.
SCADA-Ready Integration
IEC 61850 GOOSE messaging, DNP3, and Modbus RTU/TCP integration for remote monitoring and control systems. Signal lists and SCADA interface documentation supplied at project handover.
Control & Interlock Panels
Bus coupler, bus section, and generator interlock schemes with hard-wired and PLC-based logic. Loop testing and factory acceptance testing (FAT) included as a standard project deliverable.
IEC-Compliant Protection Schemes
Protection coordination studies produced to IEC 60255 and IEEE C37.112. Settings verified by independent secondary injection testing prior to energization and system handover.
