Power Grid & Telecom Networks
Design and construction of power grid networks — from connections to transformer stations. We work with distribution network operators across Poland and abroad.
LV/MV connections
Construction of low and medium voltage power connections for residential, commercial and industrial facilities. We handle the complete process — from agreements with the grid operator (TAURON, PGE, Energa), through design, to construction and technical acceptance.
Included
- Connection conditions application
- Detailed design
- DSO coordination
- Construction and acceptance
- As-built documentation
Required certifications
“The entire LV connection process handled by ALTECH from A to Z. Clean documentation, deadlines met.”
Cable lines
Installation of LV and MV cable lines in trenches, cable ducts and on cable trays. We use YAKXS, NA2XS(F)2Y and other cables in accordance with project requirements. We perform cable termination, joint installation and insulation measurements after laying.
Included
- Cable route design
- Trenching and sand bedding
- YAKXS/NA2XSY cable laying
- Joints and terminations
- Insulation measurements
Required certifications
Transformer stations
Construction and modernisation of 15/0.4 kV transformer stations — pole-mounted, indoor and containerised. We install transformers, MV/LV switchgear, metering systems and protection systems. We deliver turnkey projects including MV connections.
Included
- Building and execution design
- Container or brick station
- 15/0.4 kV transformer
- MV and LV switchgear
- Commissioning and DSO acceptance
Required certifications
Overhead networks
Construction and reconstruction of overhead LV and MV power lines. We erect concrete, wooden and metal poles. We install insulated AsXSn conductors and bare AFL conductors. We also carry out dismantling of old overhead lines.
Included
- Overhead line design
- Concrete/wood/steel poles
- AsXSn or AFL conductors
- Line accessories
- Measurements and acceptance
Required certifications
Telecommunications networks
Construction of fibre-optic and copper telecommunications networks. We lay fibre-optic and copper cables in telecom ducts, perform fibre splicing, OTDR reflectometric measurements and technical acceptance for telecommunications operators.
Included
- Network design
- Fibre or copper cables
- Fibre splicing
- OTDR measurements
- Acceptance protocol
Required certifications
Telecom duct systems
Construction of telecom duct systems using RHDPE pipes, DVR and microduct systems. We build complete duct runs including cable chambers SK-1 and SK-2. We carry out road crossings using pipe jacking or drilling methods.
Included
- Route design
- RHDPE/DVR pipes
- Cable chambers SK-1/SK-2
- Road crossings
- As-built survey
Required certifications
HDD directional drilling
Underground crossings using horizontal directional drilling (HDD) technology. This method enables crossings under roads, railway tracks, rivers and other obstacles without excavating the surface. We carry out drills from 63 mm to 315 mm in diameter.
Included
- Geotechnical analysis
- Pilot drilling
- Reaming
- Pipeline pulling
- Drill survey
