The invention relates to a quadruplex-type insulated cable (three phases insulated from, and wired to one another together with a neutral) used in the construction of a medium-voltage braided network for overhead and underground electric installations. Said cable allows: the safety distances required between phases to be substantially reduced; minimum insulation distances to be complied with, in the case of non-compliance owing to easement encroachment; and the performance indices of a distribution line to be improved (rate of forced outages and duration of same) owing to its environmentally friendly interaction. The invention is suitable for use in electrical engineering, overhead installations of electric lines or cables (H02G 7/00), installations of electric cables or lines in or on the ground or water (H02G 9/00).

The present invention provides a winding connection allowing provide a three-phase and/or single-phase system, from a two-phase feeding. Said connection is configured in primary windings as an inverted V and in secondary windings in a connection herein called "delta series" (I). In another embodiment, the invention provides a distribution transformer with 2x3 electric power, providing three-phase tension (X, Y, Z) with neutral availability in the low tension side through windings connected in delta series (I), with a inverted V winding configuration in the primary side, which are fed from only two phases (U, W) of the distribution system, with both high tension and low tension windings mounted on a same magnetic core. The transformer of the invention also provides a substantial reduction in the total losses level.

The present invention is oriented to solving existing problems in the ground systems of aerial networks of electric energy distribution, providing a pole with an incorporated ground system. Said pole has a ground lead embedded in its structure, and two connection terminal boards fitted in the upper and lower sections. This ground system completely avoids the subtraction of the lead, is effective in the grounding and ensures the efficient performance of the electrical distribution system by guaranteeing an effective connection to the ground system with operation, protection and control elements that are installed in the distribution network.
