PLP's Detuning Pendulum is designed to minimize the amplitude of vertical conductor motion during a galloping event.

Design

• Designed specifically for configuration needed (design and analysis).
• Can be configured for single, twin, tri, quad and hex bundle configuration.
• Armor rods are applied before Detuning Pendulum application in order to protect the outer aluminum strands from damage at the attachment location.
• Rubber sleeve provides an added layer of protection to the armor rods where the Detuning Pendulum is placed.
• Helical rods are used to attach the Detuning Pendulum to the conductor and help reduce the level of strain on the underlying armor rods.
• Designed to match the conductor spacing and conductor diameter for proper fit.
• 250°C Thermal Rating (Continuous)
• Weight varies between 25 lbs and 75 lbs depending on configuration.

Application

• Can be applied to a de-energized or live line
• Helicopter or bucket installation
