The World’s First Mesh Bushing Guard, since 2003
Our mesh bushing guard design offers numerous benefits for your electric utility, especially when compared with a solid bushing cover. Experience peace of mind from the increased reliability of your electrical distribution system and enhanced safety of your linemen. Once you see the difference Therm-A-Guard® mesh bushing covers make, you’ll never order a solid cover again.
Therm-A-Guard® wildlife protectors were designed with the input of expert thermographers, electrical engineers, utility linemen and substation electricians. Additionally, we use an HDPE manufactured by the Chevron Phillips Chemical Corporation; many of their chemical, process, mechanical and material engineers provided their invaluable input into our final material selection.
After over 20 years of testing, manufacturing and sales, not a single Therm-A-Guard® has failed due to a UV or manufacturing or material breakdown; in fact, most are in the same condition as when they were manufactured 10, 15 and, in some cases, 20 years ago.
Our mesh bushing covers help reduce outages due to wildlife at your electric utility.
Our mesh design allows air to flow naturally around your bushings and allows them to operate at a lower temperature.
Our mesh design allows for accurate thermal and visual inspections to be performed without removing the guard or de-energizing the equipment.
We were the first to design and market our innovative mesh bushing covers. While others have tried to copy what we started, we remain the gold standard in the industry for quality and longevity.
Our bushing covers are 100% made in America. From the Therm-A-Guard®s raw material to the shipping boxes to the design work, everything is done using American parts and using American labor. While we've been approached to outsource our operations overseas many times, as most of our competition does, we remain committed to supporting American manufacturing. This also allows us to maintain our high standard of quality control, and that helps our bushing covers to be #1 in quality.
Did you know: The smooth surface of the Therm-A-Guard® allows contaminants to be washed away with the rain.
Best Bushing Cover Design
Utility linemen across the United States and around the world prefer Therm-A-Guard® mesh bushing covers for a host of reasons, including:
Wasps and bees are naturally attracted to bushing covers. The Therm-A-Guard® mesh design won't stop bees and wasps from building nests, but they will allow a lineman to do a visual inspection of the guarded equipment and spot any potential bee or wasp dangers before getting close.
Therm-A-Guard® bushing covers are easy to install. Three of our four models are designed with hot stick handles allowing for hot stick installation without de-energizing the equipment. Your linemen can easily adapt the Therm-A-Guard for side exits where applicable.
Free samples are available for all sizes of our bushing covers. It's the perfect way to determine exactly what you need before placing a large order.
Most electric utilities routinely conduct thermal inspections as part of their preventative maintenance programs. A thermal inspection is a powerful tool used to detect hot spots on valuable electric equipment. An accurate infrared inspection allows a utility to identify and correct any potential hot spots prior to their failure or causing widespread power outages.
When solid bushing guards became common in the 1990s, they solved one problem (outages caused by wildlife) and simultaneously created another: Thermographers could no longer see the bushings underneath the covers and lost the ability to take accurate thermal readings. Also visual inspections of bushings became nearly impossible to perform. Then, in 2003, the Therm-A-Guard® was brought to market and offered an all-in-one solution to wildlife outages and thermal / visual inspections.
The Therm-A-Guard® was the first bushing cover of it's kind to protect against wildlife and allow for accurate thermal inspections to take place.
Our mesh bushing guards allow inspectors to read the oil sight gauges and visually examine the condition of the bushings. unlike with conventional solid bushing covers. Solid bushing covers make this inspection nearly impossible.
Therm-A-Guard® wildlife protectors are UV stabilized with a letdown ratio of .75% HALS UV stabilizer; both colorant and material are UV stabilized. After over 10,000 hours in a UV Test Chamber, no chalking, hazing or cracking was observed on any samples (10,000 hours in the UV Chamber represents approximately 10 years of real life sun exposure). The long life expectancy of the Therm-A-Guard® will give you the peace of mind knowing that it is an “install and forget” maintenance chore.
The three larger Therm-A-Guard®s bushing cover models are designed with hot stick handles allowing for hot stick installation without de-energizing the equipment when necessary.
