The communication signals are transmitted over at least two twisted pairs The conductors of each twisted pair are connected in parallel to constitute a power conductor. The communication and power transmissions are separated by transformers. The invention also relates to a cable for performing the method. The cable includes at least two power conductors, each being constituted by one pair of twisted insulated conductors, enclosed within an insulation sheath and outer armor and corrosion protection.
