PTFE Commonly used circuit housing materials are usually made of plastic and rubber or fiberglass. PTFE is a plastic and the best plastic material. Since its discovery in the 1930s, it has won the title of “king of Plastic” for its excellent characteristics. |
Parallel Circuit Heating Cable is a twin-conductor constant wattage heating cable.
It is designed for pipe, storage tank and other equipment heat-tracing in industrial applications.
It is widely used in carbon steel pipes, stainless steel pipes, painted or unpainted metal pipes.
The popular models in markets are 10w/m to 40w/m.

Parallel Circuit Heating Cable has a 7-layer structure.
The inner layer is a twin 12 AWG tinned copper bus wires which provide reliable, consistent electrical current.
The conductor insulation is made of FEP.
The pairing jacket secures two bus wires together and provides a wrapping surface for nichrome wire. Heating wire is made of nickel chromium.
It wraps around the pairing jacket at every other specific distance, and two ends of the heating wire connect to the bus wires.
