DESIGN CONSTRUCTION INSTALLATION
Design
- transformer substations
- power equipment—cells, panels, switchgear, substations, feeder switchgear, and main switchboards
- cable lines in trenches, along exterior and interior building structures
- overhead power lines
- street lighting
- design of electrical systems for buildings
Construction and Installation
- VAC units rated up to and including 330 kV (circuit breaker units, voltage/current transformer units, vacuum circuit breakers rated up to 35 kV; SF6 voltage/current transformers, reactors, circuit breakers rated up to and including 110/150/330 kV, gas-insulated switchgear units, etc.)
- overhead power lines with voltages up to and including 750 kV; (installation of 3/b foundations, bored piles, lattice-type metal towers, multi-sided metal towers, and reinforced concrete towers; installation of AC-type conductors, TK-type lightning arresters, fiber-optic cables, etc.) installation of power equipment—cells, panels (SHP), 6/10/35 kV switchgear (KMT, KRUNT), power supply points, incoming switchgear, main distribution boards, and enclosed switchgear with a voltage of 6/10/35 kV
- Installation of power transformers up to and including 330 kV
