HELICAL SCREENED STRANDED CONDUCTOR TWIN CABLE -- Ruggedised
This is the same construction cable as standard HST, but with a matt black polyurethane jacket – incredibly tough and resilient, and remains flexible in sub-zero arctic conditions.
Ideal for on-stage PA, and outside broadcast and film work.
Technical Specification:
Construction: Two conductors, each 30 strands of 0.10mm plain copper wire for flexibility, twisted with short lay length (30mm) for better balance and noise rejection. Cotton fillers used both to reduce microphony and to give a more regular central core profile to prevent movement of screen. Precision wound helical formation screen, 72 strands of 0.10mm plain copper wire. Overall jacket is extra flexible soft polyurethane, which has excellent handling characteristics and remains flexible at low temperatures, together with a serviceable “semi-matt” surface finish
Conductors: 30/0.10mm (0.235mm²) plain copper wire
Insulation: PVC, radial thickness 0.38mm, OD 1.4mm, Red and Black
Twisting and lay: 2 ×0.25mm² plus 2 ×cotton fillers, 30mm lay length
Screen: 72/0.1mm helically wound plain copper wire, 96% optical coverage
Capacitance: 143pF/metre core to core, 256pF/metre core to core + screen.
Maximum conductor
resistance: 69 ohms/km
Overall jacket: Polyurethane, wall thickness 1.1mm, OD 6.40mm, matt black.
