You’re working against a deadline, flipping through specs, and trying to secure compliant cables for your next project. The last thing you need is uncertainty about which sizes and core configurations are right for medium voltage aluminium cables in the UAE.
Getting that detail wrong can affect
installation planning, approvals, and overall project timing.
Understanding what's available saves you
from ordering delays and costly project hold-ups. When you're dealing with
substation feeders or industrial distribution, getting the right cable
configuration matters from day one.
Voltage Ratings You'll Encounter
Medium voltage aluminium cables come in
several standard voltage ratings. Your aluminium cable supplier in the UAE
typically stocks these configurations:
3.6/6 (7.2) kV and 3.8/6.6 (7.2) kV handle light industrial and commercial distribution.
6/10 (12) kV and 6.35/11 (12) kV serve most industrial applications across the Emirates.
8.7/15 (17.5) kV bridges the gap for specific utility requirements and particular
grid configurations.
12/20 (24) kV and 12.7/22 (24) kV power larger industrial complexes and utility substations.
18/30 (36) kV and 19/33 (36) kV handle primary distribution and major infrastructure projects.
Core Types and Conductor Sizes
Single core cables run from 50 mm² up to 1000 mm². These work for larger power
requirements where you need individual phase installation.
Three core cables range from 16 mm² to 400 mm². These bundled configurations
simplify installation when running all three phases together.
Your load calculations determine which size
you need. An experienced aluminium cable supplier in the UAE helps you match
conductor size to your requirements.
Construction Details That Matter
Every medium voltage aluminium cable
follows a standard construction pattern. The aluminium conductor forms the
core. XLPE insulation surrounds each conductor and provides excellent
thermal performance.
A copper tape or wire screen
provides the earthing path and electromagnetic shielding.
You choose between armored and unarmored
construction based on installation conditions. Armored cables include steel
wire or tape protection for underground direct burial and areas with mechanical
stress.
Unarmored cables work well in protected
conduit systems.
The PVC outer sheath provides the final
protective layer.
Special Sheath Options for UAE Conditions
Standard PVC is fine for many jobs, but in
the UAE, that’s not always enough. The climate, regulations, and type of
project often mean you need something more specific and your aluminium cable
supplier in the UAE should be able to guide you through those options.
In high-rise buildings or critical
facilities, flame-retardant cables that meet IEC 60332-3 (Category A, B, or C)
are usually a requirement. For indoor areas where people are present, low-smoke
or low-toxicity sheaths are often preferred to reduce risk if a fire breaks
out.
If the cable is installed at ground level
or in exposed spots, termite- or rodent-resistant sheaths can save you from
expensive repairs later. And in refineries or petrochemical plants, oil- and
hydrocarbon-resistant sheaths are simply part of working in that kind of
environment.
In the end, the sheath isn’t just an outer
layer. It’s what helps the cable survive the real-world conditions it’s going
into.
Making Your Selection Process Easier
Start with your voltage requirements and
load calculations. These narrow down your voltage rating and conductor size.
Consider your installation environment
next. Whether the cable runs underground or overhead, and whether it’s exposed
to chemicals or mechanical stress, will shape the type of construction you
need. The environment really does drive the decision.
Go through the project specs carefully,
especially for any mandatory sheath or fire-rating requirements. In many cases,
local fire codes leave very little room for flexibility.
It also helps to speak with your aluminium
cable supplier in the UAE early, not after everything is finalized.
They can confirm availability and flag compliance issues before they become
delays.
Choosing the right cable from the start
keeps your timeline intact. When sizes and core types are aligned with the
actual requirements, you avoid last-minute changes and unnecessary costs.
FAQs
Can I use single core cables instead of three core cables
for the same application?
Yes, but you'll need three separate single
core cables for a three-phase system. Single core offers more routing
flexibility but requires more labor. Three core cables simplify installation
when you can route all phases together.
How do I determine if my project needs armored or unarmored
cables?
Direct burial installations always need armored
cables. Underground conduit systems usually allow unarmored cables. Check local
regulations and consider mechanical protection needs based on installation
conditions.
What's the typical lead time for medium voltage aluminium
cables in the UAE?
Standard configurations from local stock
ship within days. Custom specifications or large quantities may require 4-8
weeks. Place orders early and confirm availability when project schedules are
tight.
