Heating Cables HC3/Ex-HC3

- For safe and hazardous areas

Heating cables HC3 are series heating cable used for temperature maintenance in pipelines and storage tanks to keep fluids in flow state. hey find application for process heating requirements in Oil & Gas, Petrochemical, Power, Chemicals & Fertilizers, Metallurgical, Cement, Pharma, Food and Edible oil industries.

Construction
Heating cables HC3/Ex-HC3 is a series type heating cable with single conductor (multi strand & spiraled) heating element with a primary PTFE insulation, Coated copper (ATC / NPC) braid for mechanical and earth continuity and Fluoropolymer Outer Jacket. Each length of Heating cables HC3/Ex-HC3 requires termination kits with cold lead for power connection
  FEATURES
Standards  Tested to EN 60079, EN 60079-7 & EN 60079 -30-1 requirements.
Approvals  UL & VDE Certified. ATEX Certified by Baseefa & SIRA for use in hazardous area.
Sturdy  Outer metallic braid makes it robust and suited to hostile conditions.
Uniform Heating  Generates the same rated heat output all along its length.
Easy to install  Requires no special tools & tackles to install.
Long life
 PTFE insulation used has excellent electrical properties fire resistant, inert to most chemicals,  virtually non-ageing and can withstand high temperature continuously.
