Power Line Sentry
Currently protecting more than 400,000 power lines around the world.
Thank you for your interest in Power Line Sentry, where you will find quality protection products for the harshest environmental conditions.
The Beginning of Power Line Sentry
Since the company’s inception in 1998, our mission has been to assist utilities in providing consistent and reliable power to their customers while also protecting wildlife from electrocution.
In the beginning, founder Ron Spencer, a 40-year veteran of the utility industry, became disappointed in the power line protection products that were available at the time. And, like all great innovative engineers, Ron began inventing products for his utility. One of his first inventions became the now patented Raptor Guard™ Perching Deterrent.
As we grew, so did the variations of Raptor Guard™, as you will see in our extensive product section. Power Line Sentry is now proudly protecting more than 400,000 power lines in North and South America, the Caribbean, Mongolia, and Africa. It is our duty and responsibility to help provide a safe interaction between wildlife and our electrical infrastructure.
Where Power Line Sentry is Going
As we continue to grow, we will bring products to market THAT WORK. We collaborate with leading biologists, manufacturers, engineers, and linemen to develop a complete set of products to protect both distribution and transmission structures.
Our customers provide reliable and cost-efficient power to the public. That is a complicated process when the path of electricity must travel through extreme environmental conditions.
At Power Line Sentry, our mission is to assist customers by providing the most effective protection products for the distribution of electricity around the world.
Power Line Sentry Products – Isolating vs. Insulating
We believe two effective methods can protect your power lines. The first is to “isolate” the birds and wildlife from the energized portion of your structures and equipment. The second is to “insulate” the power from contact with wildlife and the environment. Therefore, we have categorized our products in this fashion as well.
Our products are made of UV-resistant fiberglass, PVC, polypropylene, HDPE, or silicone rubber, with non-corrosive nylon and stainless or galvanized hardware. All products have superior dielectric properties.
Knowing Where to Isolate, Insulate, or Both
What does it mean to isolate?
“Isolate” is used to signify that we are trying to keep the wildlife away from the energized portion of your equipment. If you can do this effectively, you don’t need to worry about insulating the energized lines and material in the field.
Isolating wildlife from energized portions of your equipment can be more cost-effective than insulating every energized line and piece of equipment. An example of this is our Raptor Guard™ perching deterrent. If you can keep birds, especially birds of prey, away from the energized lines and equipment in the first place, there is no danger of service interruption or bird injuries/death.
Another critical reason for isolation is the Endangered Species Act. Utilities can inadvertently violate this law by providing a man-made “perch,” giving predators an unfair advantage when hunting endangered species.
Transmission and Distribution structures provide a non-natural advantage for birds of prey when hunting endangered species on the ground. In areas where protected species exist, the U.S. Fish and Wildlife Service requires that utilities mitigate their structures to prevent predators from using them as a hunting perch.
