摘要

Materials used for high-voltage electrical insulation must fulfill particular mechanical, thermal, and dielectric requirements, therefore epoxy based composites seem to be perfect ones and are broadly used for that purpose. What is very important, the properties of the final product are strongly dependent on appropriate manufacturing process with lack of material failures, as too large shrinkage, voids and cracks. Combination of proper materials (epoxy, hardener, and filler) and process parameters (mould temperature, filling time, filling velocity, initial temperature of internal parts, gelation time), as well as design and geometric parameters are essential to assure high quality of the produced components. Here, an application of advanced numerical simulations plays a very important role in identification of potential problems already during design of new products (and before a mould order) and by application of such “virtual” prototyping the best process parameters can be defined minimizing a probability of quality issues. These aspects have been covered in first part of that article.
