Galloping can cause wires to slap together, resulting in a fault or subsequent outage. The increased movement can also cause crossarms to break, bringing power lines down. To reduce galloping and its dangers, Dawson PPD uses special twisted wires called T2 conductor. This conductor is actually two pieces of wire twisted together. It is designed to present an irregular surface for ice accumulation. As a result, this irregular surface disrupts the normal wind flow around the lines and reduces the gallop. Dawson PPD implemented T2 conductor into its construction standards in 2010.
Ice and wind can be dangerous and destructive to power lines, leading to a disruption in service. When ice accumulates on power lines and the wind blows simultaneously, the wires can start to move up and down in an oscillating motion called galloping.
