Power Line Markers | Bird Diverters

ROTAMARKA™ Power Line Markers
Make Difficult To See Power Lines Highly Visible

Have undergone a battery of tests at leading Universities & independent laboratories

Years of field testing and used by major utilities & asset owners throughout the world

Certified as visible from over 4400 feet or 1.3km. FAA requires visibility from 4000 feet and AS 3891 requires visibility from 1km.

Unique combination of 3D shape, contrasting colours and rotating design creates class leading high impact visualisation of Power Lines

Increased spacing over similar products on the market reduces installation cost and total cost of ownership

Flexible installation options including from the ground with telescopic hot stick, from bucket truck with shotgun stick, from helicopter or drone

Our bird flight diverter (BIRDFLAPPA™), uses a spring clamp design, with a durable flapper attachment. Simple, yet effective, this device is designed to be durable through a range of environments. The flapper component leverages a glow in the dark effect.

Many species of birds become active outside of normal daylight conditions. Bird Diverters which are effective only during daylight hours will not be effective for these species. The glow in dark effect creates a striking contrast in low light conditions, allowing the birds to see the foot print of the power line, well after the sun has gone down.

Power Line Warning Markers (ROTAMARKA™) provide an outstanding visual warning. This can be for; low flying aircraft, mining or construction sites where accidental contact or collision is at risk.

ROTAMARKA™ Warning Marker range are purpose built and designed to provide an engineered outcome. Combing a unique feature set not seen elsewhere of three dimensional form, constant rotating movement and internally contrasting colours!

They can be installed for both temporary and long term demarcation of power lines, cables, wires and conductors.

The 3D articulated design is Patent Pending and rotates and agitates in even low wind conditions providing a superior visual indicator from all angles of approach.

Contrasting colours increase the visual impact. Known as internal contrast, this is important due to varying background lighting conditions.

The clamp is universal and fits a range of conductors opening and closing from 2-50mm. Soft jaws increase grip to stop cable creep and protect conductors.

High quality reflectors increase the visual impact.

Available with an Eye Ring fitting to work with standard live line tools. Can be installed from the ground with Telescopic Hot Sticks.

NEW, now also to be installed by Drone or UAV device. Speciality air-craft with regulation approvals in key markets mean that Power line marking is now safer, more accessible and affordable than ever! Refer to our partner website for further details here>> V-Tol Aerospace

POWER LINE STRIKES ARE AN ONGOING RISK TO
UTILITY ASSETS THE WORLD OVER

CONTACT WITH POWER LINES AROUND BUILDING AND CONSTRUCTION SITES

Construction and building sites routinely approach or encroach critical safety clearances around Power Lines. Cranes, Dump Trucks, Scaffolding, Ladders and Personnel are all at risk of contact:

FATALITIES

“Eighty-two construction workers died from electrocution in 2015, a number the Center for Construction Research and Training – also known as CPWR – calls unacceptably high”

Power Line Markers for the Building & Construction Industry (ROTAMARKA™) “URBAN MARKERS”

Building and construction sites the world over face safety risks every day. One of these is the proximity of live overhead Power Lines and Wires which pose a risk to Earth Moving equipment, Cranes and other plant which may breach clearances and come into contact with live wires. This has the potential to cause injury or even death. The cause is usually related to the overhead Powerlines not being seen by the operators of the plant and equipment. The Balmoral Markers have been specifically designed to maximise their visual impact by rotating multi coloured fins in three dimensions. When installed on Utility overhead wires, they assist operators locate and plan to avoid any potential contact between the Powerlines and plant.

LOW FLYING AIRCRAFT COLLISIONS WITH POWER LINES

Power Lines skirt or cross agricultural land and can be almost invisible to pilots. According to WMC Action News 5:

Power Line Markers for Low Flying Aircraft (ROTAMARKA™)

In the Agricultural industry, low flying aircraft and farm plant can collide with hard to see poles and wires. Aerial Agricultural activities routinely increase the risk of these scenarios occurring. Crops Duster pilots often must navigate fields where power lines cross or border. These power lines are integral to the electrical supply of the farm, but due to their hard to see nature, pose a real threat to pilots. The Balmoral Warning Marker range are purpose built and designed to provide an engineered outcome for both temporary and long term visualisation of power lines. The three dimensional articulated design is Patent Pending and rotates and agitates in even low wind conditions to provide a superior visual indicator from all angles of approach. Contrasting colours increase the visual impact. The clamp is universal and fits conductors of diameter 2-50mm. Soft jaws increase grip to stop cable creep. High quality reflectors increase the visual impact. Available in both Bayonet and Eye Ring fittings to work with standard live line tools. Can be installed from the ground with Telescopic Hot Sticks.

MINING EQUIPMENT COLLISIONS WITH POWER LINES

In a report compiled by the Queensland Government, in a localised area of mining activity within the state there was:

INCIDENTS
In A 12 MONTH PERIOD

"Six reported incidents over the last twelve months that have involved Mine mobile equipment contacting energised overhead power line infrastructure" Mines safety bulletin no. 95

Power Line Markers for the Mining Industry (ROTAMARKA™)

With onsite high voltage power and electrical infrastructure, risk of contact between plant and machinery and power lines is a constant threat. With overhead lines and wires notoriously difficult to visualise and mining activities occurring throughout the night and day, the Balmoral Markers can provide part of the preventative strategy companies can take to reduce or stop dangerous and costly incidents. The key aspect of the Balmoral Line Marker is the ability to rotate in the wind providing an element of movement. This creates a dynamic warning that is efficient in a range of lighting conditions. Mining electrical infrastructure can be set at a range of voltages required to drive plant and equipment on-site. These voltage are typically high in order to sufficiently power large machinery. This makes the potential risk even higher, since greater voltages means increased chance of the electricity finding an unplanned earth or ground.

FREQUENTLY ASKED QUESTIONS

Q: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.

Q: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. These factors combine to ensure both excellent colour stability and structural integrity of the fins.

Q: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 help prevent any conductor distortion.

Q: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.

Q:What is the weight of the Marker?

The Marker weighs around 800 grams.

Q:What Line Loading results from installation of the Markers?

The Markers combine a Universal Joint hinged mechanism with rotation which helps dissipate wind loadings and maximises the visual performance of the device. For detailed loading calculations, please refer to our data sheet.
