Electric fence insulators are a critical part of a fully functioning electric fence as they prevent the occurrence of an electrical short between the electrified fence wire and the fence posts. Heavy-duty electric fence insulators also prevent fire and electrical hazards in homes and communities as an added safety feature.
Electric fence insulators for sale can be mounted on wood posts, t-posts, rod posts, and steel posts. High-tensile electric fence insulators have a special thread and screw grip for stability. Electric fence insulators for chain link fences can be connected directly to the chain link instead of the fence post. This specialized electric fence insulator does not electrify the chain link fence itself but suspends the electrified wire away from the chain link fence. Electric fence insulators and other necessary components can be purchased in bulk to meet custom electrical fencing requirements.
The materials for electric fence insulators vary according to the specific purpose they will be used for. Hence, there are several types of electric fence insulators.
Common electric fence insulators are durable ceramic electric fence insulators and PVC-coated plastic electric fence insulators, which are easy to install.
Ceramic electric fence insulators are often used in electrical systems because ceramic can be made into complex forms required for effective electrical insulation. Porcelain electric fence insulators are made from kaolin clay, which helps keep moisture away, while antique glass electric fence insulators are valued for their craftsmanship and high electrical and cracking resistance. Glass electric fence insulators can withstand fluctuations in electrical and thermal conditions.
Both ceramic and glass electric fence insulators are capable of holding their shape for an indefinite amount of time. Non-ceramic electric fence insulators such as plastic, rubber, vinyl, and alloys are relatively cheaper and more lightweight compared to other materials.
