Grand Meyer® LTC16 SRL16-2
Self-regulating parallel type heating cable for freeze protection and temperature maintenance of non-metallic pipelines, tanks, process equipment not subjected to steaming.
Conductor made of tinned copper wires with a cross section of 0.9 mm²
Semiconductive self-adjusting matrix
Internal insulation layer*
Outer shell made of modified polyolefin
The self-regulating heating cable “Grand Meyer” type LTC16 SRL16-2 is an electric tape heater with parallel conductors. A semi-conductive, self-adjusting matrix is applied to tin-plated copper bars (0.9 mm²) consisting of a large number of stranded wires. The heat-releasing element of the heating cable is the matrix itself, which changes the heat release depending on the ambient temperature.
The internal insulation layer applied to the fuel matrix provides dielectric resistance, moisture resistance, impact and abrasion resistance, and chemical protection to the fuel matrix. This insulation layer is made using a unique patented technology by co-extrusion with a matrix on conductive wires and forms a single whole with it.
The modified polyolefin outer jacket is chemically resistant, allowing the heating cable to be used in humid or corrosive environments.
* The layer is made using a unique patented technology by co-extrusion with a matrix onto conductive wires and forms a single whole with it.
Operating principle
Parallel conductors provide 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, excluding the appearance of cold zones. The heating cable acquires self-regulating properties due to the properties of the conductive matrix. As the temperature of the matrix material increases, depending on the ambient temperature and the heat dissipation of the cable, the number of local conductive bonds in the matrix decreases, automatically reducing heat dissipation. As the temperature decreases, the number of local conductive bonds increases, leading to an increase in heat generation. This happens at every point along the length of the cable, so the power output depends on the environmental conditions along the length of the heated pipe. 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 thermal insulation layer.
Use
The most typical applications for this product are as follows: freeze protection, temperature maintenance systems for domestic non-metallic pipelines, tanks, systems for supplying technical fluids, water, condensate return. To connect the power supply, connect and terminate the cable, the Grand Meyer TTK-25 termination and termination kit is used.

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.
