AC Anti-pollution Type Three Outer Rib Porcelain Disc Insulator is a common anti-fouling insulator with large creepage distance and good self-cleaning ability.

Compared with other styles of disk insulators, the three outer rib type is easy to be cleaned by rain due to its ribless groove design, and the equivalent salt density of its surface is generally only one-third and one-half of that of the bell-type and standard type.

The products are manufactured in accordance with GB/T 7253, IEC60305 standards.

Part Ⅰ: Product Advantages

1. Good level of dirt pressure resistance for use in dusty environments

2. Large creepage distance and high withstand voltage
