KABELWERK EUPEN AG
Günter Beyer, KABELWERK EUPEN AG, Belgium, presented PIN FR solutions using a combination of inorganic PIN FR (ATH or MDH) and organoclays, generating nanocomposites. This results in a very stable, structurally resistant char formation during degradation in the case of a fire. As a result, cables using such PIN FR systems can achieve the CPR (Construction Products Directive) B2 class.
Electrical functionality (as described in DIN 4102 part 12 for security cables) in the case of a fire with temperatures up to 1000°C is maintained using polymer based insulation compounds which are transformed at higher temperatures into an electrically non-conductive ceramic.
