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.
