FIELD: electrical engineering.
SUBSTANCE: system for distributing power to more than one energy-consuming device contains tubular conductive buses and more than one energy-consuming device, wherein at least one of energy-consuming devices is a lighting device containing LED. The lighting device containing LED receives power from a three-phase AC power source. Three-phase AC power supplied to the system is ultra-low voltage power, and it is converted into DC power by means of three-phase AC/DC rectification, wherein three-phase AC power of ultra-low voltage supplied to the system is distributed by tubular conductive buses, and the voltage is less than or equal to 50 V AC RMS.
EFFECT: increase in the efficiency of electricity transmission.
