Polymeric electrical insulators

Our product range includes polymeric electrical insulators, selecting the best raw materials on the market. We take care of both the manufacturing process of the insulator and the distribution solution, as a European insulator company, to get full control of the process.

In order to offer all the possible options to our customers, our polymeric insulators have features that facilitate assembly and maintenance, thus saving time and costs for companies. The characteristics of our polymeric electrical insulators are:

✔ Hydrophobicity

✔ Self-cleaning

✔ Lightness

✔ Anti-Vandal

✔ Anti-Pollution


Innovative development of our insulators that will only bring advantages and benefits to companies: Hybrid insulators.

They are the result of ceramic insulators on the inside and polymeric insulators on the outside layer, offering hybrid insulation that makes the difference for its technical benefits.
