Field validation of a new model for uprating transmission lines

• The validation of a new technique focusing in correction of TL capacity.
• The possibility that this technique can be applied in TL up rate.
• The applications do not discard all the old conductors.
• The technique can be introduced in steps without cause great disturb in operation TL.
• The benefit to the environment since then it is possible postpone new TL.

A new model for uprating transmission lines using a technique termed “mixed conductor tensioning section” was introduced in the paper “A Model for Uprating Transmission Lines by Using HTSL Conductors”. The present paper continues the work of the previous and presents the use of small diameter conductors including a series of specific mechanical characteristics alongside conventional conductors in order to uprate the loading capacity of electrical power transmission lines. The methodology, which was successfully tested, avoids the assembly of any additional large-scale structures, since it corrects any safety breaches of the clearance distances, which jeopardize the operational limits of the transmission lines, and at a much lower cost.
