Abstract—The main factors that affect the degree of cross linking of peroxide cross-linked polyethylene
insulation in medium- and high-voltage cables have been considered. The vulcanization properties
necessary to calculate the degree of cross linking have been determined by a rotational rheometer
study. Based on the axisymmetric mathematical model of peroxide cross linking in the ANSYS Fluent
package, the temperature dependences have been obtained to calculate the final degree of insulation
cross linking. The influence of geometric dimensions of the insulated core, as well as of other process
parameters, such as line speed and temperature, on the quality of the resulting insulation has been
determined. Conclusions regarding the significant and minor factors that affect the quality of highvoltage cable products have been drawn.
Keywords: power cables, polyethylene insulation, peroxide cross linking, degree of cross linking,
