Product Specifications

Technical details and manufacturing context for Heating Cable

Definition
A specialized electrical component within Thermal Tracing Systems that converts electrical energy into heat through resistive elements, maintaining consistent temperatures in pipes, vessels, and equipment to prevent freezing, maintain viscosity, or ensure process temperatures in industrial applications.
Working Principle
Electrical current flows through resistive heating elements within the cable, generating heat through Joule heating (I²R effect). The heat is then transferred to the pipe or surface through conduction, with temperature typically regulated by external controllers or self-regulating properties.
Common Materials
Nickel-chromium alloy heating wire, Fluoropolymer insulation, Copper braid shield, Polyolefin outer jacket
Technical Parameters
  • Power output per unit length at specified voltage (W/m) Standard Spec
Components / BOM
  • Heating Element
    Converts electrical energy to heat through resistance
    Material: Nickel-chromium alloy
  • Inner Insulation
    Electrical insulation and heat transfer layer
    Material: Fluoropolymer (FEP/PFA)
  • Braided Shield
    Electromagnetic shielding and mechanical protection
    Material: Tinned copper
  • Outer Jacket
    Environmental protection against moisture, chemicals, and abrasion
    Material: Polyolefin or fluoropolymer
Engineering Reasoning
0-150°C, 120-480V AC, 5-40 W/m
Insulation breakdown at 180°C, sheath embrittlement at -40°C, voltage breakdown at 600V AC
Design Rationale: Polymer chain scission in fluoropolymer insulation above glass transition temperature (Tg=150°C), crystalline phase transition in polyethylene sheath below -20°C, dielectric strength threshold of 15 kV/mm exceeded
Risk Mitigation (FMEA)
Trigger Moisture ingress through sheath microcracks
Mode: Ground fault current leakage exceeding 30 mA
Strategy: Hermetic sealing with butyl rubber gaskets at termination points, continuous aluminum moisture barrier layer
Trigger Cyclic thermal expansion mismatch (Δα=50×10⁻⁶/°C) between copper conductor and fluoropolymer insulation
Mode: Insulation delamination and conductor exposure after 10,000 thermal cycles
Strategy: Stress-relief helical winding with 200% elongation capability, graded thermal expansion coefficient transition layers
