A semi-conductive conductor is an electrical conductor that has been treated to reduce its electrical potential. This can be achieved by doping the conductor material with impurities or by coating the surface of the conductor with a semi-conductive material. The purpose of using a semi-conductive conductor in a cable is to reduce the electric field at the conductor surface, which can reduce the risk of electrical breakdown and improve the cable’s performance.
XLPE (Cross-Linked Polyethylene) is a type of insulation material that is commonly used in high-voltage cables. XLPE insulation provides good electrical and thermal properties, as well as excellent resistance to moisture and chemicals. XLPE insulation is created by cross-linking the polyethylene molecules using a chemical or physical process. This cross-linking process creates a three-dimensional network of molecules that increases the insulation’s resistance to electrical breakdown and heat.
The Sioplas method is a popular method for producing XLPE compounds. It involves using a catalyst to promote the cross-linking reaction between the polyethylene molecules. This method can produce XLPE compounds with high cross-linking density and excellent electrical properties.
