Description

A kind of snow melt heating cable

Technical field

The utility model relates to heating cable field, particularly relates to a kind of snow melt heating cable.

Background technology

Heating cable makes the construction of cable, take electric power as the energy, alloy resistance wire is utilized to carry out heating power, just can generate heat after reaching the effect heating cable energising of heating or insulation, its temperature is at 40 DEG C-60 DEG C, by contact conduction, heat packs is trapped among the cement layer in its week, be transmitted to floor or ceramic tile again, then hot-air is added by convection type, heat conduction accounts for 50% of heating cable caloric value, and the existing in actual use heating cable that outdoor sports ground snow melt all adopts mostly requires that long service life heat production is large, therefore solves the problem and just seems very necessary.

Utility model content

The utility model provides a kind of snow melt heating cable, adopts two heating conductors, in turn to two heating conductor heating powers, adds useful life, solve produced problem in background technology.

The purpose of this utility model is to provide a kind of snow melt heating cable, comprise the first conductor as heating conductor and the second conductor that be arranged in parallel and the 3rd conductor as cold line, described first conductor and the second conductor arrange respectively as independent heating conductor; Described first conductor and the second conductor comprise a corronil heating wire and are coated on the silicone rubber insulation layer outside corronil heating wire; Described 3rd conductor comprises a tin-coated copper core twisted wire, and is coated on the polyvinyl chloride insulation layer outside tin-coated copper core twisted wire; Described first conductor, the second conductor and the 3rd conductor are coated with polyester film protective layer; total insulating barrier is surrounded by outside polyester film protective layer; foil shielding layer is surrounded by outside total insulating barrier; be provided with earth connection between total insulating barrier and foil shielding layer, foil shielding layer is surrounded by the lapping layer that blocks water, water accepting layer and restrictive coating outward successively.

Further improvement is: be provided with tension in described polyester film protective layer between the first conductor and the second conductor and between the second conductor and the 3rd conductor and strengthen muscle.

Further improvement is: the outer joint of described first conductor and the second conductor is provided with dismountable transition conductor, and transition conductor is outside equipped with and connects head.

The beneficial effects of the utility model: the utility model is by employing two heating conductor first conductors and the second conductor, in turn to two heating conductor heating powers, add useful life, the design of sandwich construction can antiultraviolet well, be applicable in deicing or snow melting, and be provided with the more tough and tensile tension of cable itself that tension enhancing muscle is, dismountable transition conductor be set at two heating conductor skins and just can be energized to two heating conductors so simultaneously, heat production more rapidly; The utility model structure is simple, has good heating property, and long service life, be applicable in snow melt.
