Modules for complete capacitor banks installation (further “modules”) are meant for capacitor banks location inside them for reactive power compensation for voltage 0,4; 6,3; 10,5 kV. Module presents itself a heat-insulated metal container, what permits to use capacitor banks in different climatic conditions, to put into operation equipment in a proper time, to reduce significantly the charges for mounting and commissioning works.
Operation terms:
- Ambient air temperature: from -60 up to + 45°С. –Height above sea level: not more 1000 m.
- Environment is non-explosive, not containing current-conducting dust, aggressive gases and vapors in concentrations destroying metal and insulation.
Capacitor banks are placed along longitudinal axis in a module.
Inside module area is equipped with lighting, local heating and ventilation systems, which keep the required temperature regime in automatic regime. If necessary a module can be equipped with a guard system and fire alarm, automatic fire extinguishers. Power energy consumption for own needs does not exceed 6 kW and depends on climatic performance and overall dimensions of module. One door and dismountable technological panel are provided in a module.
Capacitor banks for voltage 6-10 kV are placed in one module; banks for voltage 0,4 kV are placed up to 5 pcs. in one module; with stub wiring cable it’s possible to install 3 banks (with two inputs into a module). Module has an input from below by three aluminum cables with section up to 240 mm2.

In module designation the first number of type is a serial number of design which determines overall dimensions.
For doubled modules a combination of two serial numbers of the design with indication of jointing as per length (L) and width (W).
Modules with air input for complete capacitor bans placement
- There is a possibility of repeated movements because there is no need in special foundation laying.
- There is a possibility of direct connection with overhead power transmission lines thanks to the installed bushings at module mast.
