OMEGALUX® CWM (constant
wattage medium temperature)
heating cable is ideal for pipe
tracing situations that require
higher temperatures for process
maintenance as well as freeze
protection. No matter what length
of cable is needed, the wattage
(or heat) produced by each foot of
cable remains unchanged.

Bus Wires:
12 AWG copper
Bus Wire Insulation: Each bus
wire is insulated with an
11 mil FEP jacket.
Approximate Cable Size:

Standard Construction
A. Bus Wires. Twin 12 AWG copper bus wires provide reliable, consistent
electrical current.
B. Bus Wire Insulation. 11 mil FEP jacket protects and electrically insulates bus wires.
C. Inner Sheath. This insulation jacket holds the 2 bus wires together and provides
the wrapping surface for the nichrome heating wire.
D. Nichrome Wire. The nichrome resistance heating wire is the heating component
of the cable.
E. Jacket. Flame-retardant insulation jacket is made from FEP material,
which protects heating cable and ensures long service life. This material is also
highly corrosion resistant.
F. Metal Braid. Plated copper braid covering the jacket provides a positive ground path.
G. Optional Fluoropolymer Overjacket. FEP jacket provides protection from most
aqueous and chemically corrosive solutions. Add suffix “-CT” to model number.
Maximum Intermittent Exposure
Temperature/Power-Off: 200/392°C
Steam Cleaning: CWM can withstand
200°C (392°F), 150 psig steam purging
of process piping when not energized

Circuit Breaker Selection:
To determine the circuit breaker size
required, divide the W/ft (at operating
voltage) by the operating voltage;
multiply the result times the total
installed cable length in feet; multiply
this result times 1.2 to get the minimum
circuit breaker size
Caution and Warning!
Fire and electrical shock may result if
products are used improperly or installed
or used by non-qualified personnel. See
inside back cover for additional warnings.
