Communication cables
High-frequency subscription cable KVAEV
Application
Designed for subscriber access networks with xDSL technology, at rated voltage up to 50 V at a frequency of 50 Hz or up to 72 V at a direct current.
The cable can be used for vertical and horizontal installation on the inner side of building’s walls, in conditions of increased electromagnetic influences.
Cable design:
1. Conductor: tinned copper wire.
2. Insulation: PE.
3. Core wrapping: synthetic tape.
4. Inner shield: aluminium/pet foil.
5. Jacket: PVC.
