Is The (Air Insulated) Open-Wire Electric Barrier The Best?
Summary of Test Results:
Air Insulated Electric Bird Barrier lasts 3 times longer.
Air Insulated Electric Bird Barrier costs less than shocking track barriers.
Air Insulated Electric Bird Barriers are engineered to last, cost less, and work better.
Why are air insulated electric barriers so much better than electric shocking tracks?
Ask an engineer why most electrical lines are" run thru the open air" engineered primarily with "air insulation."Because Air Insulated is the only practical way to run exposed electricity economically. Without Air Insulation, the physics of Arc Flashover and Arc Burn will overwhelm a poorly designed electrical system. Designs engineered to overcome this phenomenon respect the laws of electrical fields, and thus, are "insulated thru the open air."
Without open Air Insulation, low resistant paths form. Contaminants like dust, fiber particles, sea salt, road salt, heavy exhaust, pollution, rain runoff sediments, paint flakes, surface puddles, etc., collect daily and combine with fog, rain, snow, and other sources of humidity to form conductive sediment paths. Arc Flashover burns and melts along the paths. Without Air Insulation, you must wash flat plastic track systems on a regular basis to minimize Arc Burn potential. Thus, much of the cost of flat plastic track designs may come after the initial installation. For example, prying up Arc Burned glued down track and replacing it and then power-washing it regularly to prevent more of the same. This is why plastic track systems should be used with long-term wash/replace maintenance agreements with these costs added to the actual costs of a track based system.
Although bird electric barriers or shocking barriers use a harmless and small amount of electricity, when contamination and humidity combine, Flashover and Arc Burn may easily occur, it is a law of nature. Because opposites attract, it then follows that if positive and negative charged conductors are given easy paths to flashover the electrical fields, then they will. If the positive and negative sits atop a dirty contaminated solid surface, then flashover and arc burn may readily occur. Through the years AFI's electrical and structural engineering team invented and tested several barrier strip designs. After over 15 years of experience using strips/tracks for many custom designs, AFI knows there is no way to design this law of nature out of existence. This fact is why AFI has perfected the open wire (air insulated) electric barrier, because it is engineered to last. Again, primarily by using the "open air" as the insulator, it is by far the most efficient design possible. Yes, plastic track designs are not air insulated, and thus are prone to surface burn and becoming permanently damaged (via low resistance conductive pathway burn). Permanent Arc Burn damage may occur after only a few minutes of Arc Flashover exposure.
AFI's air insulated design is different. Note that 100% of the positive conductors on plastic track electric barrier designs are directly connected onto the plastic insulator track, and are lying down flat on the track collecting contaminants. In contrast, on AFI's open wire air insulated system, less than 1% of the positive conductor makes contact with the insulator. That's over a 100 to 1difference! Yes, 100 to 1! For example, on a 100 foot-long run, only a few inches of AFI's positive conductor touches anything but the air. In contrast, on plastic track systems all 100 feet of the positive conductor touches the track insulator and there is 100 feet of solid track connection between the positive and negative conductors. Another important difference is that the AFI insulator is vertical, not horizontal, and their positive conductor sits about an inch into the open air away from surface sediments, humidity pools, and negative/grounding conductors. With AFI's open wire design, the positive conductor is where it should be, it is up away from surface contaminants and the negative/grounding conductor. AFI's open wire system is engineered to last year after year thru Phoenix summers and Chicago winters.
Again, AFI invented and reinvented the moldable barrier strip/track many years ago and says they will only use it sparingly! Because their moldable barrier strips were so unique and aesthetically pleasing, AFI inspired many imitations, yet AFI talked about them much more than they ever used them. The reasons why AFI rarely uses plastic strips/tracks are based on the economics that AFI installs and guarantees their Avian Averting System nationwide, and AFI knows why plastic strips/tracks combined with electricity are simply not economical long term! No matter the plastic track design, the electrical field dynamics are the same, plastic tracks cannot be economical; plastic tracks are arc burn prone because of the laws of nature and dirty wet horizontal surfaces! Thus, no raised/lowered ridges or molded lips will stop contaminants from collecting on the surface and then becoming humid and resulting in Flashover, Shorting, and Arc Burn. Plastic tracks are economical for temporary uses or very short runs that may be cleaned easily. In contrast, AFI's (air insulated) open wire system is permanent and engineered to last.
The AFI air insulated open wire system is designed to be scalable for just about any application, and it is engineered to last through all kinds of weather and contamination! If a customer prefers a plastic track, then AFI will help them with a professional custom design, yet AFI will highly recommend an annual maintenance contract. The AFI open wire air insulated Avian Averting System is simply the best; it is the most efficient, most effective, lowest cost, and longest lasting electric barrier available. AFI knows because they engineered it that way!
Finally, there are some environments that do not mix well with electricity, like areas susceptible to repetitive sea spray and road salt. AFI's open wire design is the only electric barrier that is sealable to lock out sea spray, road salt, and other arc burn promoting contaminants common in extremely contaminated environments. Track barriers are not sealable and are not at all usable in such environments because they will arc and burn rapidly. In addition, your AFI electric barrier may be fastened with Hurricane Grade stainless steel.
