Insulation has high electrical insulation, while at the same time providing a strong mechanical and physical barrier. It is also desirable that this material has sufficient moisture resistance if possible.

Preferably, the solid conductive resistance heating wire has a constant voltage per area, if possible. Therefore, the resistance of the wire used depends on the size of the device. To obtain a variable resistance, various alloys such as copper, tin,
Alloys of lead and platinum can be used.

The coating "self-correcting" layer of conductive material is made of, for example, braided stainless steel.

When a sharp foreign object (eg, a pin or needle) digs into a layer of “self-correcting” material (eg, a braid), the material (eg, a braid) exhibits resistance to penetration. When the material is pierced by a foreign object and subsequently removed (eg, braided strands)
Self-healing and plugging openings created by foreign matter penetration. (For example, the strands of the braid fill the void by moving to its original position.) According to another aspect of the invention, floor coverings (eg, carpet, wide woven carpet, tiles and linoleum, etc.) (A) a thermally conductive underlayer (eg, a two-component polymer) [eg, PVC manufactured by nylon and BASF;

The positive terminal, the negative terminal, and the ground terminal each have a through hole, and both ends of the wire can be passed through the holes of the negative and positive terminals, and the conductive layer can be passed through the hole of the ground terminal. The wire and conductive material are mechanically secured to the connector by a material (eg, solder or welding material) that fills the hole (when finished passing through the hole). There is provided an apparatus and a stuff.

According to another aspect of the present invention, there is provided, as a floor covering heating device to be arranged under a floor covering, an apparatus in which the above-described components are combined.

A thermostat can be connected to the device for temperature control, but this is not part of the present invention and will not be described in detail here.
