These cables follow the same design and construction principles as the standard HST and HST-R, but have larger cross section conductors (0.5mm²) for applications where a lower DC resistance is required.

Technical Specification:
Construction: Two conductors, each 64 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 (HST-HD) or 64 strands (HST-HS-R) of 0.10mm plain copper wire. Overall jacket is extra flexible soft PVC, which has excellent handling characteristics and remains flexible at low temperatures, together with a serviceable “semi-matt” surface finish or a polyurethane 'rubber equivalent' for the tougher, more demanding applications.
