ALKOMEDís High Voltage Power Projects Department specialises in the installation, testing and commissioning of high voltage power transmission projects, for both statutory utility providers and private industrial and commercial developers. ALKOMEDís experience portfolio extends to power transmission networks ranging from 21kV through 33kV, 66kV, 220kV and up to 400kV system voltage.

The range of services offered comprises the following:


ALKOMED offer a complete installation solution for high voltage power transmission substations, including transportation arrangements of heavy equipment from port to site and off loading at site; specialists for installation of primary equipment including power transformers, reactors, switchgear (GIS and AIS) and bus ducts; erection and installation of substation accessories and ancillaries; high voltage and low voltage power cable installation and termination; control, protection, ICS and SCADA system installation, cabling and termination; testing and commissioning services.


ALKOMED offer a complete installation solution for super tension power cable networks, including route survey and setting out; excavation, construction and reinstatement of power cable trenches, joint bays, pits and associated civil works; cable transportation arrangements to site; installation of super tension cable systems; post installation testing of cables.


ALKOMED offer a complete solution for the jointing and termination of super tension power cables. ALKOMED provide factory trained, experienced jointing teams, supervised by experienced cable engineers using the latest quality control methods developed for each particular jobsite to ensure a premier and reliable service for our clients.

ALKOMED offers jointing and termination services covering GIS terminations including pre-moulded, dry type and silicone oil filled; outdoor terminations including pre-moulded, oil filled, taped terminations and porcelain bushings; cable joints including pre-moulded, heat shrinkable, hand or machine taped, site vulcanised; self contained oil filled cable joints and terminations; crimped, MIG welded or thermal reaction type connectors; installation of link boxes, bonding, steel supports, cable cleats and earthing; assistance to third party jointing or terminating teams including labour and jointing assistants.


ALKOMED offer a complete solution for the testing and commissioning of super tension power cable systems, and offer this service throughout the Middle East, as an independent third party testing agency.

The latest IEC international standards concerned with extruded high voltage power cables (IEC-60840 and IEC-62067) require that all extruded insulation cables be subjected to an AC voltage test after all installation and jointing works are completed. ALKOMED has invested in a trailer mounted high voltage AC test system from HighVolt PrŁftechnik Gmbh (model WRV 83-260/80T), available for on site AC high voltage testing services throughout the Middle East for XLPE cables up to 500kV.

ALKOMED also offer additional high voltage cable testing services including DC high voltage testing, DC sheath testing, insulation resistance measurement, cable impedance measurement, conductor and shield DC resistance measurement, contact resistance measurement, progressive and field testing services, cable fault location services, pilot and communication cable testing services and cross bonding testing services.


ALKOMED offer a complete solution for the installation, jointing, testing and commissioning of fibre optic cable systems, and offer this service throughout the Middle East.

ALKOMED have realised the importance of including a complete package to its Clients when installing a high voltage cable system and have established a fibre optic cable section to provide installation, jointing and testing of fibre optic cables, including communication, distributed thermal sensors (DTS) and optical ground wire (OPGW) applications.

Using the latest technology and an experienced installation, splicing and testing team a complete fibre optic cable installation service can be offered. Using the latest Fujikura FSM-50S splicing machine ALKOMED can perform splicing and terminations on a range of fibres including single mode, multi mode, DTS and dispersion shifted. A full range of on site testing and commissioning services are also offered including fibre attenuation profile, end to end system loss and splice loss measurements, drum tests, post installation tests etc, using OTDR, stabilised LED light source and optical power meter. Fibre optic cable fault location services are also available.
