In a clean and mild pollution environment 

These are the most common and most frequently used insulators for low pollution lines, where they perform well due to their small, well-spaced ribs and a creepage distance which exceeds the requirements of the IEC 60305 and ANSI C29.2 standards.

 In heavy polluted areas 

We offer two different shapes which are recommended for areas with medium to heavy pollution. Their longer creepage distance, which exceeds the requirements of the IEC 60305 standard, is achieved due to deeper ribs and reduces the effects of pollution.

In desert area 

Due to their completely flat dielectric profile, this type of insulator is highly recommended for desert areas because the absence of ribs helps to reduce the accumulation of residues, particularly on the inner surface of the dielectric

RTV coated insulators have proven their long-term performance in all kinds of heavy and very heavy pollution 

 Similarly to the previous model, the absence of ribs on the glass part helps to reduce the accumulation of residues on the surface of the dielectric whilst promoting the cleaning action of the wind and rain.

Including low voltage and medium voltage post glass insulators set up perfect solutions.
