PORCELAIN DISC INSULATOR
Porcelain disc insulators are typically used in power transmission line. Porcelain is the most commonly used insulating material
ntil now. Not only any voltage but also any contamination level can be done by changing number of insulators.
It has unique characteristics.
• Resistance to tracking and erosion
• Resistance to weathering & UV
• Resistance to chemical & physical degradation by water
• Volume resistivity
• Resistance to corona & ozone
• Application onto glass or porcelain surfaces, especially when done in the field
Application.
· Overhead transmission or distribution line
· Tension tower to assembly tension string to tensile conductor
· Suspension tower to assenbly suspension string to suspend conductor
· Substation
