Thermon TESH Heat Tracing Cable
TESH TM
Series Constant Watt Heating Cable
Product Specifications
Application . . .
Long Line Temperature Maintenance or Freeze Protection TESH series resistance constant Watt heating cables
are used where circuit lengths exceed the limitations of
parallel resistance heating cables. TESH withstands the temperature exposures associated with steam purging.

The series circuitry of TESH provides consistent Watt-permetre power output along the entire length of the cable
with no voltage drop. A glassceramic tape layer adds additional protection to the heating cable and a fluoropolymer
overjacket provides chemical resistance while maintaining
maximum flexibility. The construction of the cable meets the
7 Joule impact test per EN50019.

Certification/Approval . . .
The Watt density limitation for TESH 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 limiting thermostats. TESH cable output and Trating are dependent upon supply voltage, cable resistance,
temperature conditions as well as additional variables.

TESH has additional hazardous area approvals
including:
• GGTN • Kazakhstan
Basic Accessories3 . . .
Power Connection: TESH cables typically require nonheating terminations at each end of the circuit before connecting to power. Contact Thermon for complete information.
Notes . . .
1. T-rating per internationally recognised testing agency guidelines.
2. Thermon heating cables are approved for the listed T-ratings using the stabilised
design method. This enables the cable to operate in hazardous areas without limiting thermostats. The T-rating may be determined using CompuTrace® Electric Heat
Tracing Design Software or contact Thermon for design assistance.
Product Features . . .
• Withstands continuous flamibility testing
according to IEC 60332-1: 1993
• Allows cable to be installed at temperatures
to -60°C

Maximum circuit lengths for TESH heating cables will be a
function of cable resistance, circuit length and operating
voltage. Circuit length, breaker sizing and earth-fault protection should be based on applicable local codes.
Earth-fault protection of equipment should be provided for
each branch circuit supplying electric heating equipment.
Note . . .
1. Longer circuit lengths are possible based on earth-fault protection with higher earthfault ratings; contact Thermon.
