Abstract
The utility model discloses an outdoor snow melting self-regulating heating cable, comprising positive temperature coefficient (PTC) thermistor alloys, teflon insulating inner sheaths, a metal mesh grid shielding layer, a stainless steel wire stiffener and a polyvinyl chloride (PVC) outer sheath. The inner center of the cable is equipped with the two PTC thermistor alloys (1) and the teflon insulating inner sheaths (2) sleeved on the outsides of the PTC thermistor alloys (1), the metal mesh grid shielding layer (3) is sleeved on the outsides of the teflon insulating inner sheaths (2), and the stainless steel wire stiffener (4) and the polyvinyl chloride (PVC) outer sheath (5) are bound together. The outdoor snow melting self-regulating heating cable of the utility model has self-regulating temperature and snow melting effects on the large area outdoor occasions needing snow melting structures.
Description
Technical field
The utility model relates to a kind of outdoor snow melt from temperature control heating cable product, relates in particular to the autonomous temperature control technique of cable, belongs to the cable and wire product technical field.
Background technology
Say that from existing cable basic structure is under polyethylene is made insulating barrier, to coat the Nb-Al alloy lead, adopts Nb-Al alloy as conductor traditionally, polyethylene is as the heating cable of insulating barrier; Nb-Al alloy heats up slow, at the bottom of the electric heating exchange rate, and autonomous temperature control; Power consumption is big, and polyethylene layer is easy to wear out, and has brought cable life short again thereupon; Leaky occurs through regular meeting, cause serious accident easily, thereby brought potential safety hazard.The conventional artificial temperature control system is complicated in addition, inconvenient installation.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of outdoor snow melt from the temperature control heating cable.
The technical scheme of the utility model cable is following:
This new-type element snow melt cable comprises that heating PTC thermistor alloy is coated with insulating layer of Teflon outward, metal knitted net, stainless steel reinforcement and PVC oversheath successively.Described cable inside center has two PTC thermistor alloys (1), and cover (2) in its outer Teflon insulation of suit, applies mechanically metal knitted screen in the outside of insulating case and covers (3), with the PVC oversheath (5) of stainless steel wire reinforcement (4) wrapping.
The utility model cable practical advantage:
This novel electrical cables can realize that the life-span is long from the temperature control snow melt, and hot friendship rate is high, the even advantage of dispelling the heat.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model internal structure location drawing;
Among the figure: 1 is the PTC thermistor alloy, and 2 are cover in the Teflon insulation, and 3 is metal knitted net screen, and 4 is the stainless steel wire reinforcement, and 5 is the PVC oversheath.
Embodiment
As shown in Figure 1; The outdoor snow melt of the utility model is from the temperature control cable; Wherein inside center has two PTC thermistor alloys (1); And cover (2) in its outer Teflon insulation of suit, be with metal knitted net screen (3) in the outside of insulating case, with the PVC oversheath (5) of stainless steel wire reinforcement (4) wrapping.
Claims (1)
1. an outdoor snow melt comprises the PTC thermistor alloy from the temperature control heating cable, cover in the Teflon insulation; Metal knitted net screen, stainless steel wire reinforcement, PVC oversheath; It is characterized in that: inside center has two PTC thermistor alloys (1); And cover (2) in its outer Teflon insulation of suit, apply mechanically metal knitted screen in the outside of insulating case and cover (3), with the PVC oversheath (5) of stainless steel wire reinforcement (4) wrapping.
