Entergy of Mississippi is changing the wood arms and insulators on the 115 KV transmission line between Bovina and Yahoo City, MS. The top cross member of the structure, which is supporting the shield wires (ground), was already a metal arm. On 26 March 2007, I photographed the Pike Electric crew performing this work.

The Pike Electric Crew: Cecil Jackson, Ray Morrow, Brent Smith,
Nicholas Fernandez, Shannon Pippen , Randy Parks.
The Crew Chief, Ray Marron, was fixing to Load One of the New
Polymer Insulators into the Bucket when I stopped him.
The Wood Pole is grounded to the Phase Line to Form an Equal
Potential Zone. The Far Insulator will be the First one replaced.
Linemen Climb the Structure, and the First Section of the Metal Arm
is delivered to them via the Bucket Truck.
The Winch on Bucket is used to Hole the Line,
while the New Insulator is being attached to the Line.
Again, the Winch on the Bucket is used to relieve the Mechanical
Load (Strain) so the Center Insulator can be removed.
The Second and Last Part of the Old Wood Arm is Removed,
and the Metal Arm connected to the Shield Wires. The Final Product.
