ITU-T K.109 PDF

This Recommendation provides guidelines for the installation of telecommunication equipment and/or antennas on utility poles carrying power distribution lines. The power lines considered are those operating in alternating or direct current, with nominal voltages up to 25 kV. These lines may be used for power distribution, street lighting, or traction lines (electrified railways).

For the procedures regarding the joint use of poles between telecommunication lines and power lines, especially the prevention of accidental contacts between these lines (power-cross), the user shall refer to [b-ITU-T K.108].

For guidance on the installation of telecommunication equipment in towers of power transmission lines (above 25 kV), the user shall refer to [b-ITU-T K.57].

Some equipment used for smart-grid applications may contain telecommunication interfaces used for supervision and control of the electric power grid, which may be installed close to or on the energized power conductors. This type of equipment is outside the scope of this Recommendation.
