Chemistry of Cross-Linked
Polythylene(XLPE), Natural Polythylene (PE) is a compound of Carbon and
Hydrogen with linear molecular structure and its principal drawback is that
it is thermally unstable at temperatures above 1100c thus limiting its
applicability for electrical power cables like HT power cables and LT power
cables. To overcome this limitation, the polyethylene is cross-linked by a
method called the Catenary Continuous Vulcanisation (CCV) process. This
process improves the properties of the cables and makes it suitable for
power transmission.
Uniflex has the latest CCV line with triple tandem extruder,
micro-processor controlled DC drives, synchronised on-line dia-eccentricity
measurement and controls, and a state-of-the-art technology which has been
imported from Royle Systems, USA.
