Description

technical field [0001] The invention relates to a 35kV environment-friendly medium-voltage ethylene-propylene insulating material and a preparation method thereof, belonging to the field of cable insulating materials. Background technique [0002] Lead stabilizers (lead compounds and lead salts, etc.) are widely used in special occasions (such as: Coal mines, seabeds, etc.) medium voltage ethylene propylene insulated cables. However, after lead stabilizers are buried, lead ions will be dissolved out, which will cause water and soil pollution. Lead is known to have cumulative adverse effects on the human body, damaging internal organs (including the kidneys, digestive system, nervous system, and reproductive system). With the advancement of science and technology, the improvement of people's own living standards, the appeal for environmental protection is getting bigger and bigger. At present, there is a trend of restricting the use of lead. Therefore, the environment-frie...
