DEVIflex™ 30T is an extremely high-quality, 360° fully screened twin conductor cable with a tough outer sheath (non UV stable). It is designed for short time use for concrete hardening only. Heating cable must be used together with an appropriate thermostat to secure against overheating and reduce energy consumption. The cold lead is an installation cable with solid conductors ensuring fast installation. A clearly visible connection avoids accidentally installing the heated cable in the wall. It has a round profile and robust construction which ensures a fast, simple and safe installation. To ensure a quality, all cables are minutely inspected including tests for Ohmic resistance, high voltage and material controls. This means that we are proud to supply our extended DEVIwarranty™.
