The 500m SS spiral copper shield cable are high flexibility and long flex life. Thanks to these properties SS is one of most popular cables for critical outdoor use applications. The external jacket in extra flexible PVC ensures anti-treading and -abrasion features. The XLPE conductor insulation, featuring a low dielectric-constant for low capacitance, is particularly resistant to high temperatures thus avoiding jacket shrinkage when soldering conductor. This particular construction is ideal for continuous winding and unwinding, its use with HD series cable reels is although recommended. All pairs are individually shielded, twisted and identified by numbers and letters printed on the internal yellow jackets. Available from 2 to 48 pairs. Each pair consists of two insulated twisted conductors and drain wire enclosed within a high-density spiral copper shield.
