WILDLIFE PROTECTION COVERS

This new innovative product advantages are:

  • Designed to cover over Crossarm mounted insulators to help protect Birds and Critters from bridging between phases.
  • Electrical faults induced by Birds and  Critters can be deadly to the animals and potentially cause expensive outages.
  • Two types – offset and centre, depending on Insulator configuration.
  • Excellent weathering resistance, time tested product.
  • Easily snap clips together to form a sturdy installation
  • Electrically tested to 25KV Class 3

Everywhere where Overhead Power Lines exist, animals, wildlife and birds can come into possible contact. Due to the nature of overhead Powerline assets, being elevated, makes them an attractive option for Birds to perch or nest. Pole Mounted Transformers generate heat, which also makes them highly sort after by wildlife especially during the cooler months. Ultimately, this interaction often proves deadly to the animal and costly to the Utility. Power Outages and Asset damage commonly occur and unfortunately for the visiting animal, it is often a life ending moment due to electrocution. One proven method of preventing wildlife contacting two points at potential voltage differences is to cover vulnerable or exposed conductors with a cover of insulating material. This effectively isolates the particular animal form the live electrical components. These covers when installed need to be built to last and endure the harsh outdoor conditions that will routinely present themselves. This includes obvious ones like the sun and uv exposure, but there can be extreme heat, wind, cold, ice, snow etc. Tracking can be another potential issue especially over time, where dirt, carbon and pollutants can build up effectively reducing clearances and providing a pathway between potential differences to arc across or track. These problems are not limited to any particular type of Utility network, with Substations, Overhead Distribution and even Transmission Lines all effected. Utility Engineers have to weigh up a potential competing set of factors. While covering the potential conductors may help eliminate wildlife interactions there are also other considerations to be met. Typically, Utility assets require routine inspections from either the ground or air. This is a preventive measure to identify faulty components in the early stage, rather than waiting for outright breakdowns. Of course, if the assets are covered, it makes these inspections quite difficult. Another concern is when covering particular Utility infrastructure, it can create microclimates or collection points for dirt, grit pollutants etc. This can build up over time and then create unintended consequences solving one problem (wildlife interaction), then creating another (tracking or asset damage). Manufacturers must consult with Utility Engineers so all are fully informed about these field or application based issues. By working hand in hand, Engineers from Utilities and Manufacturers, can customise or innovate new solutions to solve established problems. Neither Wildlife or Utility Poles and Wires are going anywhere. There is obviously a compromise and investment to make them safe for both reliable power transmission and lowest possible environmental impact. Established economies like the US are rolling out new and exciting infrastructure in this space which is set to re energise the Utility sector and create a flow of new investment and interest. Developing economies such as Africa are also driving electricity infrastructure investments to get power to the people. Where these assets are being rolled out, gives the opportunity for engineers and planners to design such infrastructure from the get-go with best practice mitigation and wildlife management in mind. In the end, wildlife interaction with Utility Assets is not going away and has a material impact on Utility metrics, cost and delivery performance and can put a risk wildlife. While no one perfect solution exists to eliminate this issue, there are real solutions at hand. Taking the time to analyse the issue, quantify the problem and invest into the solution will yield dividends for proactive Transmission and Distribution companies and the Environment alike. These solutions have the potential to pay for themselves and then some, in little time at all given the frequency of these interactions.
