Use for Outdoor/indoor two cores flat 8 configuration telephone drop wire
Application:
Drop cable is for connecting power amplifier and broadcasting systems, transmitting the audio signals amplified by the amplifier
Construction:
1: conductor : 0. 5mm, 0. 6mm, 0. 8mm or 0. 9mm bare/ tinned copper wire request
2: insulation: HDPE, PVC or request
3. The assembly should be consisting of two conductor lay parallel insulated to form a figure 8 configuration. It should be possible to separate the drop wire into two fully insulated conductors by cutting along the interconnecting web.
4. Polarity identification should be provide by a single ridge tracer longitudinally molded along the jacket throughout the intere length the drop wire unaided eye and to the touch.

Electrical requirements and tests:
Sparkling: Voltage application during the manufacturing process
(after the extrusion) in order to detect pores or other insulation
failures
Minimum insulation resistance at 15.6 ºC:
- Between conductors: 92 Mohm/km (500 VCC power must be applied
during 1 minute. This test must be realized dry. )
Minimum dielectric breakdown strength at VCC:
- between both conductors: The insulation must resist during 3
minutes a continuous voltage of 7500 VCC. This test must be
realized dry)
