Ensto's new SDI82, SDI83 and SDI84 line post insulators for medium voltage overhead line networks.
In order to extend the insulator's lifetime, the insulator neck is made of insulating plastic (PA6-GF30). This reduces the electric field around the insulator, which in turn reduces the burdening of materials.
The new composite line post insulators have been tested according to the IEC 61952:2008 and IEC 60060-1:2010 standards.
As the coating of the insulators is made of two-component silicone that gives excellent dielectric strength and makes it resistant to UV radiation and the most extreme weather conditions.
