Standard Construction
A. Buss wires. Twin 16 AWG copper buss wires
provide good current capability.
B. Matrix. A semiconductive polymer core whose
electrical resistance varies with temperature. When
process temperature drops, the core’s heat output
increases; conversely, as process temperature
rises, heat output decreases.
C. Jacket. This flame-retardant insulation jacket is
a thermoplastic rubber material with excellent
water resistance. It also resists certain mildly
corrosive chemicals.
D. Tinned-Copper Braid. The braid covering the
jacket provides additional mechanical protection
and a positive ground path.
E. Optional High Temp TPR Overjacket. The TPR
overcoat protects the braid and provides
resistance to certain inorganic chemical solutions.
Add suffix -CR to the model number.

energy and eliminating hot spots
along the pipe. The parallel
construction makes it easier to
install than zone or series types
of cable since it can be cut to
length at any point on the pipe.
It can be overlapped without
overheating the cable.

SRF cable is ideal
for keeping metal and plastic pipes
warm in commercial construction,
institutional buildings, and some
industrial freeze-protection
applications. SRF cable is
constructed of a self-regulating
polymer core that varies its output
along its entire length, saving
