EngineeringPower factor correction for industrial facilities
A poor power factor inflates demand charges and loads your distribution for no useful work. How power factor correction works, how to size a capacitor bank, and when to use detuned reactors.
EngineeringEarthing and bonding for busbar trunking systems
A busduct run is only as safe as its earth path. How earthing and bonding work in busbar trunking, the role of the housing, and what to verify on site.
Testing & CommissioningCable testing and commissioning: VLF, tan delta and partial discharge
Before a medium-voltage cable is energised it should be proven. A plain-English guide to VLF withstand, tan delta and partial discharge testing — and what each result tells you.
EngineeringACB vs MCCB vs MPCB: choosing low-voltage switchgear
Air circuit breakers, moulded-case breakers and motor protection breakers each protect a different part of a low-voltage system. A practical guide to where each one belongs.
EngineeringData centre power distribution: a busway design guide
From utility intake to the rack, data centre power distribution lives or dies on reliability and flexibility. Here's how overhead busway compares to cable, and what to specify for GCC facilities.
Buying guidesHow to choose busbar trunking: a buyer's guide for consultants and contractors
Selecting busbar trunking for a project means weighing current rating, voltage drop, ambient, IP rating and standards. Here's a practical 8-step checklist used on real GCC and MENA projects.
EngineeringDesigning busduct risers for high-rise towers in the GCC
Tall buildings in the Gulf bring unique constraints — long vertical runs, high ambient temperatures, and tight shaft tolerances. Here's how we engineer busduct risers that work.
EngineeringWhat is busduct? A practical guide to busbar trunking systems
Busduct (or busbar trunking) replaces bulky cable runs with a compact, low-impedance distribution system. Here's how it works and where it makes sense.
StandardsWhy 50°C ambient changes everything in GCC switchgear specs
Switchgear catalogues are built around a 35–40°C reference ambient. In the Gulf, that assumption breaks. Here's how we derate properly without over-specifying.
ProductsLinkk vs Megaduct: choosing the right busduct system for your project
Both Linkk and Megaduct deliver KEMA/ASTA-tested busbar trunking — but they're optimised for different project profiles. Here's how to choose.
Buying guidesBusduct installation cost vs cable: a real comparison for the GCC
On a 4000 A rising main in a 50-storey tower, what does busduct actually cost compared to a parallel cable solution? A practical breakdown of materials, labour, shaft space and lifecycle.
StandardsIEC 61439 compliance: what it actually means for your switchgear
IEC 61439 is the bedrock standard for low-voltage switchgear and busbar trunking. Here's what its design verification actually covers — and why it matters at handover.
EngineeringSandwich vs cast resin busbar: which busduct technology suits your project?
Sandwich-type and cast-resin busbar trunking solve overlapping problems with different engineering trade-offs. Here's a clear comparison of insulation, fire performance, cost and best-fit applications.
MaintenanceSwitchgear maintenance schedule for GCC plant rooms: an annual checklist
GCC ambient and humidity accelerate switchgear wear. Here's the annual, semi-annual and quarterly checklist we recommend for low-voltage switchgear in Dubai, Abu Dhabi and across the Gulf.
CommissioningOnshore vs offshore commissioning: what actually differs
On paper the test plan looks similar. In practice, offshore commissioning is a different discipline — driven by HSE, helicopter logistics, and the cost of every hour of platform time.
EngineeringSpecifying low-voltage distribution for hospitals: a practical checklist
Hospitals carry life-safety circuits, sensitive medical equipment and mixed clean/dirty loads. Here's the LV distribution checklist we work through on hospital and healthcare projects in the GCC.
EngineeringManaging voltage drop on long feeders — busduct vs cable
On long horizontal runs and rising mains, voltage drop quietly limits how far you can push the load. Here's how busduct compares to cable and where each makes sense.
Project notesInside the Marina 101 busduct distribution: a project note
Marina 101 is one of Dubai's tallest residential towers. A look at how the busduct distribution was specified, supplied and commissioned — and what we'd do differently today.
