Electric insulation material and/or impregnation resin for a wrapping tape insulation for a medium- and/or high-voltage machine

An impregnation resin for insulation systems using a wrapping tape, the resin comprising:

• a base resin including a siloxane-containing compound and a hydrocarbon-based compound;
• and
• a siloxane-based curing agent with cationic and anionic curing catalysts, the curing agent causing the base resin to cure to a thermoset material;
• wherein the siloxane-containing compound forms a —SiR2—O— backbone in the thermoset material;
• the hydrocarbon-based compound forms a —CR2— backbone in the thermoset material;
• wherein R represents an organic radical selected from the group consisting of:
• aryls, heterocycles, nitrogen-substituted aryls or alkyls, oxygen-substituted aryls or alkyls, and sulfur-substituted aryls or alkyls;
• and
• the siloxane-containing compound makes up between 20 and 30 mol % of the base resin and the hydrocarbon-based compound makes up between 70 and 80 mol % of the base resin.
