Crosslinked polyethylene

In some applications, the insulating material of cables is exposed to extreme temperatures. In automotive technology, for example, engine cable harnesses and transmission connections must withstand temperatures of well over 100 °C.

Cable manufacturers have divided the cables for these stresses into temperature classes up to 150 °C. Various insulating materials can withstand these temperature stresses, including polyvinyl chloride( PVC), polypropylene( PP) and crosslinked polyethylene (XLPE). The latter has the DIN/VDE designation 2X, can withstand mechanical stress and overloads, and can be used at temperatures of up to 150 °C.

As far as "crosslinking" is concerned, this is a chemical process in which the molecules crosslink when irradiated.
