An EPC contractor is not measured by adjectives. What decides whether a company can carry a job is numbers: to what voltage level, at what production capacity, with which software and against which standards. Everything on this page is of that kind.
Highest substation voltage
Equipment specification ceiling
Underground dry XLPE cabling
Tallest telecom mast
Hot-dip galvanizing capacity
Largest monopole shaft diameter
Six disciplines, each to its own voltage ceiling. The model below shows exactly that.
Each mast rises exactly to its own voltage level. Tap any of them.

Substation construction as EPC and turnkey. It starts with surveying and geoelectrical and geotechnical testing, continues through levelling, earthworks, perimeter wall, control building, equipment foundations and cable trenches, and ends with the earthing system, gantry structures, aerial busbar, yard equipment, LV and MV panels, cabling, testing and commissioning.
EPC · turnkey · 20 to 400 kVThe whole build chain: surveying, survey check and route profiling by ground and aerial methods, foundation excavation, reinforcement and concreting, tower sorting, assembly and erection, conductor and shield-wire stringing, and OPGW fibre installation.
PC and EPC · 20 to 400 kVUnderground energy transmission with dry XLPE cable, by direct burial and by cable tunnel. Its second use is converting an overhead line into underground cable to free the line right of way — where a city has reached the line and the corridor has to be cleared.
Dry XLPE cable · buried and tunnelledTurnkey telecom site construction equipping three-legged, four-legged and monopole masts under super-heavy loading, up to 150 m tall. Ground fibre-optic lines for bandwidth upgrades and urban mast camouflage are handled by the same unit.
Up to 150 m · super-heavy loadingAerial fibre networks built on both de-energised and energised lines. Hot-line work means the network never leaves service for a moment — a specialism not every contractor takes on.
Cold and hot line · OPGWNetwork studies, obtaining high-capacity industrial electricity supply from Tavanir, and resolving transmission line interference. This link comes before design and settles the connection point and the capacity.
Up to 400 kV · Tavanir coordinationThree links tied together in one turnkey contract.
Three disciplines — high voltage, low voltage and civil — produce basic and detailed documents against the latest edition of the standards.
A vendor is chosen after evaluation, not before. Once chosen, the manufacturing process stays under supervision.
From the soil test to energisation. Installation and testing crews carry the work to permanent handover.
Four groups, each with its own toolset.
Single line diagrams, layouts and sections, earthing calculations, insulation coordination and lightning protection, clamp and fitting location and codification, and technical specifications for equipment from 1 to 420 kV. Executive drawings and equipment purchase packages are also closed out here.
Equipment is procured and delivered in three families across all voltage levels.
Four units completing the chain from raw plate to packed, galvanized steel.
Cutting, punching and assembly of angle and plate on CNC machines, supervised by the manufacturing technical office.
Rolling and welding of monopole shafts up to five metres in diameter, for telecom masts and transmission towers.
Inspection before process, during process and final. The emphasis is in-process, because a defect caught there can still be corrected. Results are logged and reviewed with statistical analysis.
An in-house galvanizing plant with European equipment and an annual capacity above 30,000 tonnes — so the project schedule is not tied to another factory's queue.
Occupational risks, after qualitative and quantitative assessment, are eliminated, substituted or controlled by managerial and engineering methods, or a combination of both. The declared goal is to drive the annual accident rate to its minimum.
Specialist work-at-height training at IRATA levels, with general and specialist personal protective equipment and continuous health examination and monitoring.
