TESH HEATING CABLE OF CONSTANT POWER
Constant power resistive heating cables of the TES series are used when the length of the circuit exceeds the limits for parallel heating cables. TESH cables are designed to work in an environment with a high exposure temperature associated with steaming. The TES series cables provide a constant output specific power over the entire length of the cable. The glass-ceramic tape additionally protects the heating cable, and the fluoropolymer shell ensures the resistance of the heating cable to chemical attack, while maintaining maximum flexibility. The cable design conforms to the EN50019 standard, "7 Joule impact test". TESH cables are designed for use in conventional (unclassified) areas and are certified according to the ATEX standard for use in explosive areas of Category 2 and 3 (Zone 1 and 2).
