Balmoral WM-RW Series Overhead Conductor Warning Markers

Balmoral WM-RW Series Overhead Conductor Warning Markers

The Balmoral Warning Marker is a purpose designed Hi Visibility Line Warning Marker ideal for low hanging wires, construction zones, low flying agricultural aircraft and many other applications.

  • The 3D Design with reflectors enables vision from all angles as the marker flag rotates with a breeze.

What is the strength of the clamp?

  • Nylon 6 is a high strength material that has been used in the Electrical Industry for various connectors and clamps for over 30 years.
  • It has also been used in many industries where High Strength is required, including the Motor Industry for various vehicle components such as Water Pumps etc.

Will the flag make a whistling sound when spinning?

  • The Warning Marker has been tested in a wind tunnel at varying wind speeds of up to 30m/s and during testing did not produce any noise.

What is the UV resistance?

  • Nylon 6 has been used in the Electrical Industry for over 30 years in various outdoor components and clamps.
  • It includes UV stabilisers and has been proven to be very stable in outdoor conditions.
  • All the metal components are made of Stainless Steel or Brass and are known to be very durable in outdoor conditions.

Will the clamp damage the cable when tightened?

  • No. All Clamping Components are manufactured in high strength Nylon 6 (not metal) and the Clamp Fingers are lined with rubber which will mould around the conductor and not crush or deform it.

Is their any vibration or harmonics imposed on the line from the Warning Marker?

  • Based on the wind tunnel testing performed, no vibration was evident.

What cleaning is required?

  • As per normal Power Line Components, no cleaning is required, however, if desired, the Warning Marker can be cleaned with mild detergent and water
