Cut-outs
Energy - T&D
Features of cut-outs
- High shock resistance;
- Low weight (from 3 to 10 times lower with respect to the porcelain cut-out);
- High resistance in cold environments (low temperature);
- High resistance in highly polluted environments (pollution);
- High resistance against ultraviolet radiations;
- High arc resistance;
- Greater dispersion distance with the same spark gaps;
- Lower transportation, packaging and storage costs;
- Greater hydrophobicity and corrosion resistance properties that keep the surfaces of the insulators clean.
