33 kV Polymer Disc Insulator – Strong & Dependable for Overhead Line Insulation
The 33 kV polymer disc insulator is an innovative product for insulated overhead electricity lines up to medium–high voltage levels. Constructed using composite materials, the 33kV fist provides a durable, non-brittle option to traditional porcelain insulators. With high mechanical strength performance, better weatherability and a hydrophobic surface, the 33kV polymer disc insulator keeps maintenance to a minimum and reliability high, even in the harshest environmental conditions.
Qualifying environments include those typical in industrial settings, various coastal conditions, and even where extreme weather affects the population.

Advantages of 33kV polymer disc insulators:
Light weight and non–brittle – Safe for handling because of weight and similar නThe use of extra support when putting in or removing the local area grid. However, if the applications is properly rated the polymers should work without any issues.
The insufficient or inadequate level of installation of additional structures to protect the operator accidents while the lines are upright or horizontal.
Possible utilizing it while its deployed.
