Designation
Low Voltage Electrical Switchboards "NKU” are designed to receive and distribute electric power (0.69 kV, 50 (60) Hz
three-phase alternative current) among consumers.
Application
It functions as:
- General switchboards and sub- switchboards, Automatic Transfer Switch (ATS) panels
- Aggregate panels of electro-technology installations control stations
- LV Switchgears of Packaged Transformer substations
- Utilities Switchboards for Electric Generating Stations, etc.
Functional Capabilities
- Electric installations power supply protection-ATS arrangement from electric power system (max. 2 lead-ins) and emergency power supply sources, in particular, from electric power system (max. 2 lead-ins) and diesel run power plan (max. 2 lead-ins)
- Control of power supply system parameters and status
- Local, remote and automatic control of power consumers
- Reception of control signals and signals generation of consumers status via wire and digital communication channels (Modbus, Profibus)
Construction Merits
"Freecon” Low Voltage Electrical Switchboard is a freely configurable system based on "F4” in-house / "NIPON” OJSC /
form factor — (for 6,300 A current, max.) and based on "SIVACON S8” licensed unified form factor — (for 7,000 A current ,
max.) and "Logstrup” — (for 8,500 A currents, max.).
Low Voltage Electrical Switchboards are connected to Distribution Networks:
- By cables from below and top
- By buses / bus ducts from top, laterally
Consumers are connected to Low Voltage Electrical Switchboards:
- By cables from below and top
- By buses / bus ducts from top
