Abstract
The utility model relates to a PTC alloy heating cable, and consists of a core, an insulating layer and a sheath. The utility model is characterized in that the core (1) of a PTC alloy heating unit is positioned at the circle center of the cable section, and the concentric circle of the section inside out is an insulating layer (2), an inner cushion layer (3), a shielding layer (4) and an outer sheath (5) in sequence. A PTFE tape is wound and wrapped on the alloy surface to form an excellent electrical insulating layer, which can resist a temperature as high as 250 degrees Celsius system. The inner cushion layer can play a role of enhancing insulation. The shielding layer is a tinned copper braided mesh, thereby can strengthen the integrated intensity and enlarge the area of heat radiation and grounding protection. The outer sheath is used for damp-proofing and corrosion resistance. The heating cable adopting the PTC alloy as the heating core has a considerable ability of power regulation, a function of self-protection and a more safe and reliable operation.
Description
Affiliated technical field
The utility model belongs to the electric heating equipment, a kind of PTC alloy heating cable.
Background technology
Traditional metal electric heating material, temperature coefficient of resistance is very little.When the thermo electric material temperature raise, heating power did not have obvious change, so the electric heating made of traditional electrical hot material must have extremely reliably that temperature control system guarantees its normal use, otherwise can produce excess temperature and damage.Novel PTC alloy material has great temperature coefficient of resistance.Along with heating temp raises, resistance also can increase severely greatly by the utmost point, and heating power has obviously and reduces, even reduces to 20%.Therefore do the heating cable that the heating core is made with the PTC alloy, have the certain power adjustment capability, play the self-protection effect, as the electric heating element that needs A.T.C, use safer reliably, yet also do not have this product at present.
Summary of the invention
The purpose of this utility model provides a kind of PTC alloy heating cable of energy A.T.C.
The utility model utilizes the positive temperature characterisitic of PTC alloy, does the heating cable that the electric heating core is made needs A.T.C, and core is a PTC alloy 1, and section concentric circles from inside to outside is insulation 2, inner cushion layer 3, shielding 4 and oversheath 5 successively.The poly fourfluoroplastics band is wrapped to be constituted insulating barrier, high temperature resistantly reaches 250 ℃ and have fabulous electrical insulating property in alloy surface; Inner cushion layer is extruded by poly fourfluoroplastics, plays the reinforced insulation effect; Screen is woven into net with tinned copper wire, and its effect is to increase bulk strength, increasing thermal radiation area and ground protection; Oversheath also is to extrude with poly fourfluoroplastics, is used for moisture-proof anticorrosive.
Accompanying drawing 1 is the sectional view of the design's heating cable.
Claims (1)
1, a kind of PTC alloy heating cable, comprise core, insulating barrier and oversheath, it is characterized in that PTC alloy heat generating body is positioned at the center of circle of the cross-section of cable as core (1), section concentric circles from inside to outside is insulation (2), inner cushion layer (3), shielding (4) and oversheath (5) successively.
