Application
ELEKTRA SelfTec®16 ready2heat heating cables
are intended for the antifrost protection of:
• pipeline systems up to 50 mm in diameter,
• sprinkler systems,
• drain pipes for condensate outlets in air condi-
tioning and ventilation systems,
• actuators,
as well as for the protection against snow and ice of:
• gutters,
• downpipes,
• roof drains.
Characteristics
ELEKTRA SelfTec®16 ready2heat self-regulating
heating cables increase their heating power when
the temperature of the heated system drops and
adequately decrease it when the temperature
increases. Change of power only occurs in these
places where ambient temperature changes.
Self-regulating heating cables are never in danger
of overheating and that is why they may touch
and cross.

Selection
Pipeline systems, sprinkler systems, etc.
Length of the heating cables depends from:
• pipe’s diameter,
• min. ambient temperature on the installation site.
Value 1 signies parallel positioning of the cable
along the pipe. Values higher than 1 signify the
length of the heating cable per 1 m of heated
pipe. In this case, the cable should be spiralled
along the pipe.

Selection of the adequate length of the heating
cables depends from:
• min. ambient temperature in the area of the
installation site.
* if the building is located in the regions of intense
snowfall

Materials
– required for the installation of heating cables
on pipes and pipelines:
• ELEKTRA SelfTec®16 ready2heat self-regula-
ting heating cable (in the box),
• self-adhesive installation tape (in the box),
• self-adhesive aluminium foil min. 0.06 mm
thick, approx. 50 mm wide (available in the
offer),
• thermal insulation for pipes.
– required for the installation of heating cables
in gutters and downpipes:
• ELEKTRA SelfTec®16 ready2heat self-regula-
ting heating cable (in the box),
• gutter and downpipe holders (available in the
offer),
• support bar (available in the offer).

Installation on pipes
• ELEKTRA SelfTec®16 ready2heat self-regula-
ting heating cable should be selected matching
the pipe’s length according to table 1,
• The heating cable should be mounted along the
pipeline in its bottom part with self-adhesive
installation tape xed every 30 cm. If, basing
on the table, the selected cable is longer than
the heated pipe, the cable should be installed
spirally,
• For plastic pipelines, install self-adhesive alumi-
nium foil on the pipe before xing the heating
cable. This will improve the temperature distri-
bution on the surface of the pipeline,
