Parallel heating cables are typically available in two distinct variants.
Parallel constant wattage heating cable.
Constant wattage heating cables as their name suggests are designed to deliver the same power output irrespective of pipe temperature.
Nickel chromium alloy wire contacts bus wires at regular intervals.
Parallel constant wattage heating cable.
Three paralleled stranded copper wire as the bus wires with insulion layer fep then wrap the nickel chromium alloy.
For line lengths of up to 200 m for maintain temperatures of up to 200 c.
Because of their constant power output circuit breaker sizes may be reduced compared to self regulating heating systems.

Parallel bus wires so it is.
Parallel heat tracing cables parallel heat tracing cables use two normal copper conductor wires which run in parallel along the length of the wire and form the basis of live and neutral.
Constant wattage and self regulating also known as self limiting.
Output power constant independent of temperature changes.

We have been producing constant power heating cables for over 30 years.

These constant wattage parallel heating systems offer an economical alternative while maintaining the advantages of cut to length cables.
Parallel connection to each heating zone.
Parallel heat tracing cables parallel heat tracing cables use two normal copper conductor wires which run in parallel along the length of the wire and form the basis of live and neutral.
Parallel constant wattage cables.
We produced the world s first parallel resistance cut to length heating cable in 1978.
Nichrome wire diameter determines the output power per unit length.
