HD 203
HF-75Flex Trishield
Class A+
Application Area
This HF-75 type Flexible Trunk cable is specifically designed for use in the field of CATV and multimedia network, for both, direct burial and for installation in duct or pipes. The sheath is made of UV resistant black PE. This particularly low-loss cable wşth Skin/Foam/Skin Gas injected PE insulation is characterised by its high stability of the electrical data. It fulfills Class A++ screening category referring to EN 50117-2-3.
