A system of transport, distribution and/or sale of electric energy to industrial frequency to inclusive voltage between 600V and 1200V essentially constituted by normalized cables for lines to low voltage, three-phase transformers with two BT voltage in delivery and circuit breakers. The system is characterized by the fact to transform the electric voltage from medium voltage (3000.30000V) to a level of voltage understood between 600V and 1200V through three-phase transformers MT/B1T1 of power 50, 100 or 160 kVA or about, to transport with normalized cable of low voltage, aerial or underground, or with other fit mean till to a near place to the utilization where the voltage suffers a second transformation to the level of voltage in use, generally 400/231 or 220/127 Volts and till 110V.
