Applications Overview

The J-Y(St)Y Screened Telephone Cable is for use in telecommunications systems with a voltage rating of 300V for the analogue and digital transmission of data and signals. This European telephone cable is manufactured in accordance with Standard VDE 0815, making it particularly suitable for use by German telecoms installers and their counterparts across many parts of Europe.

This cable is suitable for fixed indoor installations within dry and damp premises, under or on plaster. This cable is not suitable for laying in ground or in water.

J-Y(ST)Y cable

J-Y(st)Y cable construction

Conductor Solid plain copper (Class 1)
Insulation Polyvinyl Chloride (PVC) according to VDE 0207
Screen Duplex tape and drain wire
Outersheath PVC according to VDE 0207

The J-Y(ST)Y cable has a screen of Duplex tape and drain wire to reduce electrostatic interference both to and from the cable. The larger conductor sizes than the British CW1308 results in lower losses and therefore superior performance.
