TB 669-2016现行

This TB is a summary of methods given by various experts and guidance to analyse and understand thermo-mechanical forces effects with large conductor cross section XLPE cable systems: It is intended as the proposal of guide to thermo-mechanical design of extruded cable systems with 1000 mm² and greater conductor cross-sections with the objective of increasing reliability and reducing the risk of poor planning and installation. It will be one of the major inputs for the updating of the TB 194 “Construction, laying and installation techniques for extruded and self-contained fluid filled cable systems” by WG B1.61 recently installed.
