FBT Heating Cable

Self-regulating heating cable FBT

Heating Cable type ESRS Datasheet – Termination Instructions

>> FBT Heating cable is a parallel resistance, cut to length on site self-regulating heating cable designed for frost protection, process pipework maintaining and hot water temperature maintaining.

Type FBT heating cable adjusts heat output to equal the heat loss from the pipe work. As pipe temperature falls under no-flow conditions or due to decreases in external or internal temperature, FBT increases output. As the pipe temperature increases under flow conditions or as a result of increasing external or internal temperature so output from FBT decreases.

Construction

The heating cable has a core comprising two bus-wire conductors contained within an extruded semi-conductive self-limiting heater core with an outer insulating polyolefin sheath.

The cable has an earth protection screen in the form of a Foil Jacket covering a multi strand earth lead.

The cable is finished with a further protective thermoplastic outer sheath over the earth screen.

The heating cable is certified for use in hazardous areas.

k = ThermalConductivity of insulation layer at its
mean temperature

Tp= Maintain Temperature

Ta= MinimumAmbient temp

D1= Inside Diameter of theInsulation Layer

D2= OutsideDiameter of the Insulation Layer
