HV and LV networks and substations
High and low voltage is where AZEMCO started, and where we are trusted most.
We build 11 kV networks and distribution substations, lay and terminate HV and LV cables, install transformers and ring main units, and test circuits and protection relays before they are energised. For 132 kV works we build the troughs and lay the cables, and coordinate the DEWA-approved HV contractors who make the joints and terminations.

The scope we design, install and test.
Network owners give us repeat orders: Empower for HV and LV works across its chiller plants, DEWA for 132/11 kV substation works, and Nakheel for 11 kV networks on Palm Jumeirah.

- Distribution substations11/0.433 kV substation fit-out: transformers, LV boards, earthing, ventilation and the room handover to DEWA.
- 132 kV cable worksTroughs and cable laying for DEWA substations, and the diversion and protection of live circuits around new roads and rail.
- Cable laying and terminationHV and LV cables pulled, laid and terminated, with excavation, road crossings and reinstatement by our civil team.

- HV and LV generatorsSupply, installation and commissioning of HV and LV generator sets.
What makes the difference on this discipline.
Trusted on live networks
Much of our network work is on assets that stay in service while we work. Isolations, permits to work and switching are planned with the operator’s control room, and nobody works on a circuit that has not been proven dead.
Trench to termination under one roof
Our civil team digs the trench and builds the duct bank; our cable team lays and terminates. One programme runs from excavation to energisation, with no gap between two contractors.

View projectBefore you appoint us.
Do you carry out 11 kV works yourselves?
Yes. AZEMCO is a DEWA-approved LV/MV contractor and holds DEWA approval for private 11 kV cable laying.
What do you do at 132 kV?
We build the troughs and lay the 132 kV cables for DEWA substations, and divert live circuits around new roads and rail. Joints and terminations at 132 kV are made by DEWA-approved HV contractors, whose work we coordinate.
Can you work on a live network?
Yes, under the operator’s permit and switching procedures. We carried out the HV and LV works across Empower’s semi-permanent chiller plants under repeat orders.
