Ceramic Insulators vs. Porcelain Insulators
What exactly are the differences between ceramic and porcelain insulators? Although both can be used to make insulators for your electric fence system, these are not interchangeable terms. In reality the major variations between the two come down to: the clay composition and the temperature at which they are fired.
Ceramic is made of red, brown, or white porous clay and fired between 2,100° to 2,300° Fahrenheit. It is less expensive than porcelain, but it is more susceptible to chipping and cracking in cold weather. When ceramic is fired, the color is only baked into the top layer.
Porcelain is made from refined, white clay called kaolin and is fired at temperatures as high as 2,600° Fahrenheit. Porcelain also has color throughout. Porcelain is denser and less absorbent than ceramic, so it can easily withstand moisture and harsher weather conditions. However, porcelain is more expensive. Porcelain is sometimes referred to as China, because the process in which it is made was developed in China. The term porcelain often signifies high quality ceramics.
Zareba® offers high quality porcelain insulators. Our porcelain insulators are designed to hold electrified wire near fence posts without losing energy through the post. Porcelain insulators have higher insulating properties than plastic insulators and will not break down due to sun damage. When properly installed, porcelain insulators should be able to last the life of your fence. Available for in line and corner posts, porcelain insulators can handle any size fence wire including high tensile wire, poly wire, and poly rope.
