Construction

Thermon KSX: Self-regulating heating cable, product specifications

  1. Nickel-plated copper bus wires (1.3 mm²)
  2. Semiconductive heating matrix and fluoropolymer
    dielectric insulation
  3. Tinned copper braid
  4. Fluoropolymer overjacket provides additional protection
    for cable and braid where exposure to chemicals or
    corrosives is expected.

Applications for Thermon KSX Self-Regulating Heating Cable

High performance KSX self-regulating heating cables are designed specifically for high heat loss freeze protection applications or process temperature maintenance where steam cleaning is not required.

The heat output of KSX cable varies in response to the surrounding temperature by reducing its thermal output with increasing temperature.

KSX cables are certified for use in ordinary (nonclassified) areas and in potentially explosive atmospheres in accordance with the ATEX Directive and the IEC Ex Scheme..

Notes:

¹Cable may be energised at other voltages; contact us for design assistance.
²Thermon heating cables are approved for the listed T-ratings using the stabilised design method. This enables the cable to operate in hazardous areas without limiting thermostats. The T-rating may be determined using CompuTrace® Electric Heat Tracing Design Software or contact us for design assistance.
³Information on additional accessories to complete a heater circuit installation and to comply with approval requirements can be found in the "Self-Regulating Cables Systems Accessories" product specification sheet (Form TEP0010U).
