Environment-friendly dual-core heating cable for electrothermal floor heating

Abstract

The invention relates to an environment-friendly dual-core heating cable for electrothermal floor heating. The elliptical heating cable is a dual-core heating cable. The cable comprises alloy heating cores, an insulating layer, a grounding layer, a shielding layer and an outer protective sheath. The high temperature resistance insulating layer wraps the alloy heating cores. Metal wires evenly wrap the insulating layer to form the grounding layer. The grounding layer and the insulating layer are connected together. The shielding layer is arranged outside the grounding layer. The shielding layer is divided into an inner layer and an outer layer, the inner layer is formed by fully wrapping an aluminium foil or by braiding a metal wire, and the outer layer is formed by winding a metal wire clockwise with the inner layer of the shielding layer being an axis. The outer protective sheath is disposed outside the shielding layer. Compared with the prior art, the environment-friendly dual-core heating cable exhibits great mechanical strength, is durable and tensile, is resistant to aging for a long time, is highly safe, enables quick heating and temperature rises, and is environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to a heating cable, in particular to an environment-friendly double-core heating cable used for electric floor heating. Background technique [0002] Heating cable is a cable structure made of heating wire, using electricity as the energy source, and using alloy resistance wire to energize and convert the electrical energy into heat energy to achieve the effect of heating or moisturizing. Usually, there are single-conductor and double-conductor. The heating cable is usually composed of a heating core, an insulating layer, a grounding layer, a shielding layer and an outer sheath. After the heating cable is energized, the current passes through the heating cable. The form of radiation is emitted to heat the heated body. With the development of economy and society, people's awareness of safety, environmental protection and health are constantly improving, and more stringent requirements are put forward for the safety performance, he...

Problems solved by technology

With the development of economy and society, people's awareness of safety, environmental protection, and health are constantly improving, and more stringent requirements are put forward for the safety performance, heating performance, mechanical performance, and environmental protection performance of heating cables. The insulation layer and protective cover of the existing heating cable are made of polyvinyl chloride (PVC) material. After a long time of electrification and heating, the material is easy to age, easy to produce plasticizer smell, and has a short service life. The heating core uses nickel aluminum alloy as the heating conductor. It heats up slowly and consumes a lot of power. The shielding layer is formed by directly covering the insulating layer with a metal shielding material. The heating cable is not easy to install and bend, and it is easy to twist. The shielding effect is not good. The grounding wire uses a single grounding wire , once it is bent and twisted during the installation process, it will cause poor connection and cause serious safety hazards

During the actual use of existing heating cables, problems such as aging, poor grounding, slow heating, reduced calorific value, non-environmental protection, and increased energy consumption will occur after long-term use
