The electric heat tracing tape consists mainly of the following key parts:
It is the core part of the electric heat tracing tape, responsible for transmitting electrical energy to other parts of the heating tape and generating heat through resistance.
Usually made of copper, nickel, or other metals with good conductive properties, it has good electrical conductivity and mechanical strength.
The core tape may be composed of polymer conductive carbon particles and two parallel busbars to achieve current conduction and heat generation.
Located outside the conductive core wire, it serves the purpose of isolating the current and providing protection, ensuring that the current flows only in a specific path, preventing leakage and electric shock accidents.
Usually made of high-temperature and corrosion-resistant materials such as Polyvinyl Chloride (PVC), Polyethylene (PE), Fluoroplastic, or Polytetrafluoroethylene (PTFE).
The quality and thickness of the insulation layer have an important impact on the insulation performance and high-temperature resistance of the electric heat tracing tape.
Metal Shielding Layer (Metal Braided Layer/Metal Shielding Mesh)
Located outside the insulation layer, it mainly enhances mechanical strength, shields electromagnetic interference, and provides grounding protection.
Usually woven from materials such as copper mesh, aluminum mesh, stainless steel wire, or copper wire.
The material and weaving density of the metal shielding layer determine its mechanical strength and shielding performance.
It is the outermost layer of the electric heat tracing tape, providing protection for the internal structure as well as wear resistance and corrosion resistance.
Usually made of materials such as Polyvinyl Chloride (PVC), Polyethylene (PE), Fluoroplastic, stainless steel, or polyurethane.
The quality and thickness of the outer jacket have an important impact on the wear resistance, corrosion resistance, and waterproof performance of the electric heat tracing tape.
Additionally, based on specific application needs and system design, the electric heat tracing tape may include other accessories such as thermostats, junction boxes, tees, crosses, and end caps. These accessories perform various functions in the electric heat tracing tape system, collectively ensuring system stability and reliability.
In summary, the various components of the electric heat tracing tape work together to achieve the insulation and heating of the object being heated. When selecting and using electric heat tracing tape, it is necessary to comprehensively consider the performance and quality of each component based on the specific application scenario and requirements to ensure system stability and reliability.
