Cable Assemblies can be used in almost any atmosphere, but some environments pose specific challenges that need to be separately addressed. One such environment is when a cable assembly is installed in areas highly vulnerable to rodent damage. Installations requiring rodent protection can include any outdoor application, indoor industrial installations, residential applications, food/grain storage areas, or any area that offers shelter and food for rodents.
How Rodents are attracted to cable assemblies?
Rodents are attracted to cable assemblies for several reasons. The housing of the cable used in the cable assembly offers an excellent surface for the rodent to aggravate on due to the presence of plasticizers, aromatic odors given off by the insulators themselves, the bright colors used for the sheaths, and the texture of the jacketing materials.
All rodents have four incisor teeth that grow continuously throughout their lives. To keep these incisors short, rodents have the continuous urge to gnaw/chew. If readily available dietary products such as hard-shell nuts are not available, rodents will turn to other articles in their environment, such as cable assemblies, to fulfill the urge to gnaw.
Methods to repel Rodents
There are several methods to protect cables from rodent damage and ultimately discouraging rodents from chewing on the outer surfaces of a cable assembly jacket. Those methods include housing the cable with a physical barrier, the use of lethal toxins (poisons), the use of repellants, or the use of non-lethal chemicals.
