Series Constant Watt Heating Cables
Series constant watt heating cables include a metallic heating element. Circuit length has a direct effect on the power output.
These cables are designed speciﬁcally for temperature maintenance of piping, tanks and equipment with longer circuit length requirements.
Series cables fall into two basic types:
1. Flexible, polymer-jacketed cable for longer tracing circuits
2. Semi-rigid, metal jacketed, mineral insulated cables for high temperature service.
