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.
Outer Sheath
Nichrome 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 bus-wires.
An extruded outer sheath of silicone rubber is then placed over
the core and heater element to complete the heater cable
assembly.
Over Jacket
Over Braid
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.
