METHOD AND INSTALATION FOR FABRICATION OF HEAT RESISTANT TRANSMISSION LINE HAVING A THERMO SOFTENING CORE

The invention relates to new, heat resistant, recyclable conductor for electrical transmission lines having composite load bearing core made by pultrusion using a thermoplastic polymer matrix, by in situ polymerization of the cyclic monomers and/or oligomers of the matrix polymer, optionally in the presence of polymers prone to melt phase transreactions, with reinforcements consisting of high modulus and strength fibers, optionally textile structures made of such fibers, which are mostly oriented along the axis of the core (see Figure 1. The load bearing cable core). The invention relates further to process(es) aimed at the continuous production of said conductor core (see Figure 2. Scheme of the coextrusion production process with braided and/or wound synthetic fibers and Figure 3. Scheme of the production process with braided synthetic fibers).
