[0026] Working principle:

[0027] Installation Phase

[0028] By using external screws to pass through the connecting hole 306 on the mounting rod 305 to fix it to the outside, and pushing the reinforcing sheath 1 from the side, the sliders 304 at both ends of the mounting rod 305 slide into the slide groove 303 on the connecting strip 302, thereby achieving the effect of fixing the reinforcing sheath 1 on the connecting strip 302 to the installation position, and the connecting strip 302 has the effect of wrapping the four corners of the reinforcing sheath 1, thereby playing a role in alleviating external force stamping.

[0029] Use phase

[0030] During use, the busbar insulation 6 has insulating fillers on the outside, so that the busbar insulation 6 and the busbar 7 are wrapped and protected, and the concave connecting seat 401 fixes the position of the heating wire 2 to avoid displacement of the heating wire 2 during use, which affects the service life of the heating wire 2. The glass fiber 402 can effectively ensure the structural stability and excellent high temperature resistance after cabling, and long service life. The outer wall of the reinforced sheath 1 is affixed with an outer film 8 and a color-changing paint 9. As the heat emitted by the heating wire 2 is transferred to the surface temperature of the reinforced sheath 1 and contacts with the color-changing paint 9, the color changes to monitor use. At the same time, the color-changing paint 9 can be replaced by tearing the outer film 8 to improve the overall safety during use.
