Underground Cabling Systems

Design and installation of medium-voltage (MV) and high-voltage (HV) underground cable networks. We handle trenching, duct bank construction, cable pulling, jointing, termination, and insulation testing for projects across the harshest environments in the Middle East and Africa.

MV (11kV–33kV) and HV (66kV–132kV) underground cable networks
Trenching, duct bank, and direct-buried installation
XLPE, PILC, and specialty cable handling for harsh environments
Cable jointing, termination, and high-voltage testing
Route survey, GIS mapping, and as-built documentation
02

Overhead Transmission Lines

Engineering, procurement, and construction of overhead line systems from 11kV distribution to 132kV transmission. Includes tower and pole erection, conductor stringing, sagging, and comprehensive earthing systems.

11kV distribution to 132kV transmission lines
Steel lattice tower and concrete pole erection
ACSR, AAC, and AAAC conductor stringing and sagging
Earthing, lightning protection, and shield wire systems
Route clearance, environmental permits, and ROW coordination
03

Medium & High-Voltage Substations

Turnkey substation design and construction up to 132kV. Air-insulated (AIS) and gas-insulated (GIS) options. We handle transformer installation, switchgear configuration, protection relay systems, busbar design, and full control room integration.
