Coated overhead conductor

Abstract

A polymeric coating can be applied to an overhead conductor. The overhead conductor includes one or more conductive wires, and the polymeric coating layer surrounds the one or more conductive wires. The overhead conductor can operate at a lower temperature than a bare overhead conductor with no polymeric coating layer when tested in accordance with ANSI C119.4 method. Methods of applying a polymeric coating layer to an overhead conductor are also described herein.

Description

[0001] References to related applications [0002] This application claims priority to US Provisional Application No. 611925,053, filed January 8, 2014, entitled COATED HIGH VOLTAGE TRANSMISSIONOVERHEAD CONDUCTOR, which application is hereby incorporated by reference in its entirety. technical field [0003] In general, the present disclosure relates to polymer coatings that reduce the operating temperature of overhead high voltage electrical conductors. Background technique [0004] As electricity demand increases, the need for higher capacity electricity transmission and distribution lines increases. The power that a transmission line can deliver depends on the current-carrying capacity (carrying capacity) of the line. However, such ampacity is limited by the maximum safe operating temperature of the bare wire carrying the current. Exceeding this temperature can cause damage to the conductor or other components of the transmission line. However, the resistance of a cond...

Problems solved by technology

However, such ampacity is limited by the maximum safe operating temperature of the bare wire carrying the current

Exceeding this temperature can cause damage to the conductor or other components of the transmission line

However, the resistance of a conductor increases as the temperature of the conductor or power load increases
