PHT - heating cable with constant power output

PHT heating cable with constant power output is intended for frost protection or for process temperature maintenance in metal or non-metallic pipelines, storage tanks and other equipment.
It is a high performance heating cable with maximum temperature resistance of up to 285 ° C. This heating cable can be adapted at the installation site to match the exact pipe lengths without complicated design requirements. Thanks to the high flexibility of the silicone jacket of the heating cable, it is especially suited for space restricted applications.
PHT cables are approved for use in normal environments, zones 1, 2 and zones 21, 22.

BASIC ACCESSORIES:

Terminal boxes for connection of heating cables - are used for powering, connecting and branching of heating cables.

Cable termination
PHT heating cables with constant power output require the use of a termination set UTK344/200+.

Power output curves:
Output power for jacketed cable attached to the insulated metal pipeline at the voltage values listed below:

Type of cable
Nominal voltage 230 V AC
 Power output (W/m)
 10PHT  10
 30PHT  30
 50PHT  50
 70PHT  70


* NF ... Fluoropolymer jacket providing additional protection in places where the cable is exposed to the influence of organic chemicals or corrosive atmospheres.

Certification: SIRA 02ATEX3078  II 2G Ex e IIC T2 Gb

For information on further certification contact Generi, s.r.o.

Note:

1. Cables can also be used for other voltages, for information contact Generi staff.
2. Temperature classes are according to internationally recognized standards of authorized institutions.
3. Heating cables are approved for temperature classes using a stabilized design. This allows the use of cables in potentially explosive atmospheres without limiting thermostats. For design
of heating circuits, please contact Generi, s.r.o.
4. For additional accessories for complete installation of the heating cable and for compliance with the approval requirements, refer to the heating cable installation guide.
