HEATING CABLE TYPE SCBX
Parallel circuit heating cable - Constant
watt for hazardous areas
Certificate NO SIRA 03 ATEX 3376U
Parallel circuit heating cable is designed to
be cut from reel lengths and site
terminated to suit pipework. The heating
cable consists of a number of short
heating zones, each connected across a
pair of continuous bus-wire conductors.
Each complete heating zone will give its
full rated design output with circuit voltage
applied to the bus-wire conductors.
Construction
The heating cable has a core comprising
two bus-wire conductors contained within
an extruded silicone rubber sheath. The
sheath is notched on alternate sides at
predetermined intervals to expose a short
section of bus-wire conductor.
Nickel-chrome resistance wire is wrapped
at regular spacing around the core as a
continuous conductor, making contact with
the bus-wires at the exposed points.
After completion of the heater conductor
wrapping, a high temperature soldered
joint is made at each contact point
ensuring that a number of conductor
strands are securely bonded to the buswires.
An extruded outer sheath of silicone
rubber is then placed over the core and
heater element to complete the heater
cable assembly.

The cable has an earth screen outer braid
of tinned copper or stainless steel.
Where additional protection is required for
corrosive conditions extruded silicone
rubber sheathing can be placed over the
braided cover.
