Detailed Description:
I. Introduction
Shielded Single-core Heating Cable utilizes high-performance alloy resistance wire as the heating material, combined with a unique heating core structure, offering superior quality and reliability. The power connectors and terminal caps are completed at the original factory, with multi-layer technology treatment ensuring reliable wiring and overall waterproof, anti-corrosion, and insulation performance. This system is widely used in various heating projects across the country, holding a significant market share.
Section 2: Principle of Operation for Heating Cables
The heating cable core consists of cold wire and hot wire, encased in an insulating layer, grounding, shielding layer, and outer sheath. Once powered, the hot wire heats up and operates at temperatures between 40-60°C. The embedded heating cable in the fill layer transfers heat energy to the heated body through both thermal conduction (convection) and the emitted 8-13um far-infrared radiation.
The composition and working principle of a heating cable ground radiant heating system: Power supply line → Transformer → Low-voltage distribution unit → Residential electricity meter → Thermostat → Heating cable → Radiates heat indoors through the floor.
a. Power-driven;
b. Using heating cables as the heating element.
c. Principle of heat conduction for heating cables.
