Heating of main pipelines up to 25 kilometers.
ThermTrac heating system provides heat retention for long pipelines, no cumbersome power distribution system. One electrical input allows heating a pipeline up to 25 kilometers. ThermTrac system is ideal for maintaining temperatures, frost protection and heating of pipelines.
The system generates heat thanks to alternating current, passing along the inner surface of the heating tube. Electro system- and explosion-proof - there is no current on the outer surface.
Design
1 Nickel Plated Copper Stranded Wire
2 Fluoropolymer dielectric insulation
3 Fluoropolymer protective shell
4 Steel heating tube
The skin-effect heating system is based on the insulated ThermTrac conductor.
NPO TeploKhimMash supplies individually for a specific project nickel-plated copper conductor with dielectric insulation and protective sheath. Freeze protection and low temperature systems use Teflon-insulated tinned copper conductors. Polyolefin insulated nickel-plated copper conductors for the best thermal performance, flexibility and strength, required for many high temperature applications.

The maximum power is limited by the permissible conductor temperatures. Maximum power for Teflon insulated conductors, but a conductor with polyethylene insulation is significantly cheaper. therefore, if the power of one heating tube is not enough, several.
The longer the ThermTrac system, the more voltage is needed to maintain the required current. Working voltage (and, accordingly, the number of systems - power points) limited by the permissible voltage for the insulation of the conductor. Increasing the number of heating tubes reduces the required current in each, and, accordingly, the operating voltage in each tube. Hence, increasing the number of tubes, we also reduce the number of power points. The mains voltage is not critical for the system - transformers can be made for almost any voltage.
