Grand Meyer® PHC-16

Parallel type self-regulating heating cable for freeze protection. Used for maintenance of pipelines and tanks that are not subjected to steaming, freezer frost heave prevention. Can be used to install inside the pipeline using pipe coupling.

Conductor made of tin-plated copper wires with a cross section of 0.5 mm²

Semiconductive self-adjusting matrix

Internal insulation layer made of modified polyolefin

Wire shield (max. resistance ≤18.2 ohm/km)

Outer shell made of modified polyolefin

Grand Meyer PHC-16 is an oval type low temperature self-regulating heating cable with semi-conductive carbon matrix and parallel 0.5mm2 tinned copper bus wires. The heating intensity depends with number of the conductive paths between the bus wires, which varies with the surrounding temperature. The modified polyolefin 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 modified polyolefin outer jacket is UV resistant, allowing the heating cable to be used on open areas.

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.

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.

Grand Meyer PHC-16 heating cable can be installed inside the pipeline using the Grand Meyer HCF pipe coupling.
Note: Grand Meyer PHC-16 cable is not approved for drinking water.
Grand Meyer TTK-25 connection kit is used to terminate heating cable to cold lead for power supply.

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 3-4 times the rated current for which the circuit breaker is designed.
