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.

Minimum length of heating cable is 25 ft. Visit us online for heat cable accessories and controls.

Ordering Example: CWM12-1C, 120 Vac heating cable, 12 W/ft, 100-ft length.

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.

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
