Grand Meyer® UHC-40
Self-regulating parallel type heating cable for universal use for freeze protection and temperature maintenance of pipelines and tanks that are not subjected to steaming.
Conductor made of tin-plated copper wires with a cross section of 1.0 mm²
Semiconductive self-adjusting matrix
First layer of internal insulation*
Second layer of internal insulation made of modified polyolefin
Wire shield (max. resistance ≤18.2 ohm/km)
UV protected outer jacket made of modified polyolefin
Grand Meyer UHC-40 is an tape type low temperature self-regulating heating cable with semi-conductive carbon matrix co extruded together with PE insulation and parallel 1.0mm2 tinned copper bus wires. The heating intensity depends with number of the conductive paths between the bus wires, which varies with the surrounding temperature.
Two layers of internal insulation and outer jacket provides
dielectric resistance, UV resistance, moisture resistance, impact and abrasion resistance.
Self-regulating heating cable is protected by a wire screen, which provides mechanical protection and ensures reliable grounding along the entire length of the cable.
* The insulation layer is made using a unique technology by
co-extrusion PE insulation together with carbon matrix.
Application
Applications for this product are as follows: roof and gutter frost protection, pipeline frost protection, temperature maintenance for industrial and domestic pipelines, tanks, fire protection systems, systems for supplying technical fluids, water, condensate return lines, comfort floor heating, radiant space heating, freezer frost heave prevention.
Operating principle
Parallel bus wires provides voltage along the entire length of the heating cable, the semi-conductive matrix is a continuous heating element. This design allows you to cut the cable anywhere. The number of the conductive paths between the bus wires varies with the surrounding temperature. When ambient temperature decreases, the number of the electrical paths of the will be increased generating heat. As temperature increases, the heating matrix expands and reduces the number of electrical paths. So the power output depends on the environmental conditions. The ability of self-regulation eliminates the risk of overheating or burnout of the cable when it crosses itself or when the cable passes through the isolation layers.

For use with type C circuit breakers according to IEC 60898-1:2003.
* At the moment when the heating cable is turned on, a current jump occurs (starting current). Within ≈300 seconds after switching on, the current value stabilizes. The maximum starting current can be 4-5 times the rated current for which the circuit breaker is designed.
