Self regulating Heating Cables

Product catalog summary
Overview: This document provides technical specifications and guidelines for self-regulating heating cables designed for medium and low-temperature applications. These cables are used for freeze protection and temperature maintenance in pipes, valves, and tanks.
Specifications:
  • Temperature Range: Medium temperature cables operate from -40°C to +215°C, while low temperature cables operate from -30°C to +85°C.
  • Voltage: Maximum voltage for non-hazardous areas is 277V. Standard versions for 110V and special versions for 24V or 48V are available.
  • Construction: Cables consist of two copper conductors within a semi-conductive polymer (ETFE) that adjusts resistance with temperature changes.
  • Certifications: ATEX, FM, CSA, GOST certifications for hazardous areas, except for the Base version.
Installation Guidelines:
  • Circuit Breaker Selection: Use the provided tables to select the appropriate circuit breaker based on model, cable length, and minimum start-up temperature.
  • Length Calculation: Calculate cable length as pipe length plus 10% for fittings and flanges. Consider additional length if spirally wound.
  • Safety Devices: Install an electrical safety device according to regulations. Use a thermal magnetic circuit breaker with 30 mA differential control for protection.
Performance:
  • Power Output: Power output varies with temperature and voltage, with specific values provided for different conditions.
  • Maximum Exposure Temperature: Ensure pipe temperature does not exceed the cable's maximum exposure temperature during operation or when switched off.
Product Variants:
  • Base: FEP jacket only.
  • Reinforced: FEP jacket with tinned-copper braid.
  • Anti-corrosion: FEP jacket with tinned-copper braid and fluoropolymer overjacket.
  • Watertight: TPE jacket with tinned-copper braid and TPR overjacket.

 Self regulating Heating Cables-1

Heating Cable Self regulating, medium temperature For freeze protection or temperature maintainance up to 150 °C. For use in pipes, valves, tanks, etc. The two copper conductors are located within an extrusion of a semi-conductive polymer (ETFE) whose resistance varies with temperature. The characteristic is expoited to supply the required power in proportion to the process temperature and allows the cable to be overlapped without burning as the power reduces to almost zero as the polymer temperature limit is approached. Poorly insulated cable or cable that cross insulation or voids will not be affected by such use. However it is important to ensure that the pipe temperature does not exceed the maximum exposure temperature of the cable either when operating or switched off. Base (FEP jacket only) Reinforced (FEP jacket + tinned-copper braid) Anti-COrrOSion (FEP jacket + tinned-copper braid + fuoropolymer overjacket) Exposure temperature (even when switched off): minimum -40 °C, maximum +215 °C. Minimum bending radius: 40 mm. Certifications (except for Base version): ATEX, FM, CSA, GOST for use in hazardous areas (EExe II T4/T3*). Parallel construction allows the cable to be cut on site and terminated and spliced by the installer. Circuit length up to 190 m long, depending on output, minimum temperature and type of circuit breaker. For quick calculation of cable length: pipe length + 10% for fittings, flanges, etc. Consider more if spirally wound. [*): Area class depending on model, see above chart An electrical safety device must be installed A thermal magnetic circuit breaker (curve C or K) with 30 mA differential control must be used Maximum voltage, out of hazardous areas: 277 Standard versions for 110 V supply are available on request. Special versions for 24V cable maximum length.
