Series Resistance Constant Watt Heating Cable TEK THERMON
TEK series resistance constant watt heating cables
are used where circuit lengths exceed the limitations of
parallel resistance heating cables. Circuit lengths up to
3,658 m can be energized from a single power supply
The series circuitry of TEK provides consistent watt-perfoot power output along the entire length of the cable.
TEK cables are certified for use in ordinary (nonclassified)
areas and in potentially explosive atmospheres in
accordance with the ATEX Directive and the IEC Ex
1 Heating Conductors (2 or 3)
2 Fluoropolymer Dielectric Insulation
3 Fluoropolymer Pairing Jacket
4 Nickel-Plated Copper Braid (BN)
5 Fluoropolymer overjacket provides additional protection
to cable and braid where exposure to chemicals or
corrosives is expected.
Power Connection: All TEK cables require a Terminator
or cold lead transition for connection to power. Refer to
the back of this specification sheet for details.
End-of-Circuit Termination: An end-of-circuit termination
must also be used with TEK cables. This termination,
detailed on the back of this specification sheet.
The watt density limitation for TEK cables is directly
related to the desired maintain temperature. Thermon
is able to ensure the T-rating based on a stabilised
design that enables series constant watt heating
cables to operate in hazardous areas without the use
of limiter thermostats.
