Nexans 33kV CWS is a heat shrinkable termination kit designed for indoor/outdoor use on solid insulation cables with copper or aluminum conductors and copper wire screens. It offers reliable performance for voltages up to 36kV and cross-sections up to 1600mm². The kit includes red mastic tape, stress relief mastic pad, and red insulation tube for added protection and insulation. Installation is straightforward, involving cable preparation, lug crimping, mastic application, and heat shrinking. The result is a durable and weather-resistant termination suitable for various applications.
