In the period from 2011 to 2014, we carried out turn-key construction of the 110/15kV Widziszewo transformer- and distrbution substation in the H5 system together with a 110kV overhead and cable power line
The scope of works included design works, construction and installation works as well as start-up and commissioning of the facility, including:
- preparation of building plans and specifications, detailed design and as-built design of the 110/15kV station, together with arrangements and legal permissions,
- preparation of building plans and specifications, detailed design and as-built design from the field bay SE 110/15kV Widziszewo to the placement of the branch tower in the existing 110kV line,
- construction of a 110 kV double-circuit overhead and a 0.9 km long cable power line, (including a 120 m route length of underground cable and a 0.78 km of overhead line segments on lattice towers),
- construction of a , 1.1 km long 15 kV underground line from the Widziszewo power substation to a substation of PKP (Polish State Railways),
- introduction of a 110kV line and fiber-optic cable,
- construction of overhead 5-panel 110kV switchgear,
- construction of a station building, containing two section 15kV switchgear with 110kV and 15kV control room, together with auxiliary rooms and installations,
- execution of secondary circuits 110kV and 15kV for electrical power system protection and station`s telemechanics,
- construction of a 16-panel double fed R-15 Kv indoor switchgear, type D17-P.
