Polymer Insulators

Polymer insulators have a number of advantages, they will not crack and does not chip, that is, they are resistant to vandalism antics, damage during installation and transportation.

The hydrophobic surface properties and significant resistance to tracking erosion, polymer insulator need not be cleaned from industrial pollution.

The insulator has a breakdown voltage and discharge characteristics that exceed the properties of glass and porcelain insulators. Market polymer insulators there in the last century, but active replacement of porcelain and glass isolated on the polymer being from 2005.

Insulator passed in its development through several stages: from the polyolefin sheath and "Barbecue" type of assembly, and to silicone rubber-cast performance. Currently, polymer insulator is present in almost all areas: power lines, substation equipment, switching equipment, electrical railways. That is not surprising, since the composite insulators have a number of advantages in comparison with glass and porcelain. Until 2006, a major barrier to the widespread introduction of polymer insulators was the price. However, most manufacturers in 2006 came to a new technical level of production and managed to put Insulators linear bolt into a single price series with porcelain and glass.
