Insulator for 20 kV- SHTIZ-20D
Absence of latent defects inside insulated body. Each insulator passes optical control on absence of vials in a power head of insulator;
Control of insulators on a corner of polarization of passing light allows to guarantee absence of internal pressure, stable characteristics of electrical insulation, which are unattainable in ceramics;
It not appears micro cracks in the body of insulator during exploitation period;
It not appears micro cracks in the body of insulator during exploitation period;
It is easy to find the taint insulator across HV line. Insulator is applicable for all poluttion and humidity levels and is very popular in the HV lines for oil and railway sector. Metal clamp on the cap of insulator allows to complete wire fixation work faster.
