Abstract
The utility model discloses a high strength temperature sensitive power cable comprising three conductors and two elastic alloy conductors. The three conductors are respectively provided with an insulation layer in an extrusion-molded manner to form three insulation wire cores, which are uniformly disposed on areas of a Y-shaped skeleton. The skeleton adopts a steel band, which is provided with an elastic layer having a thermoplastic elastomer in an extrusion-molded manner. The two elastic alloy conductors are respectively provided with a temperature sensitive insulation layer. The two elastic alloy conductors, which are wrapped by the temperature sensitive insulation layers, are intertwisted together to form an insulation temperature sensitive element. The insulation temperature sensitive elements are disposed in the skeleton in a delta-shaped arrangement. The outer sides of the three insulation cores and the skeleton are sequentially provided with a taped covering and a sheath layer. In the utility model, the temperature sensitive elements are disposed in the skeleton, and are electrically connected with an external controller, therefore the cable or the device can be prevented from being damaged. The cable has advantages of good anti-extrusion performance, and high mechanical strength.
Description
Technical field
The utility model relates to the power cable field, specifically a kind of high strength temperature-sensitive power cable.
Background technology
The insulation of common power cable and sheath material are generally polyvinyl chloride, cross-linked polyolefin etc., and these materials can be aging until the cable outlet fault rapidly in cable overload or high temperature occasion etc.How to avoid cable in overload or the safe operation of high temperature occasion, protection and other equipment are not damaged, and the tensile strength of strengthening simultaneously cable is the problem that industry is explored always.
The utility model content
The purpose of this utility model provides a kind of high strength temperature-sensitive power cable, on the basis of common cable, adds temperature-sensing element; when the temperature rise of cable overload or ambient temperature reach the temperature that cable can bear; the temperature-sensing element action is cut off the electricity supply, and protection cable or equipment are not compromised.
The technical solution of the utility model is as follows:
High strength temperature-sensitive power cable, include three conductors and two elastic alloy conductors, it is characterized in that: described three conductors outward respectively extrusion moulding have insulating barrier to consist of three to thoroughly do away with the edge cores, three thoroughly do away with the edge core is evenly distributed on Y shape skeleton regional, and described skeleton adopts the outer extrusion moulding of steel band to have the elastic layer of thermoplastic elastomer (TPE) to consist of; Described two elastic alloy conductors have respectively the temperature-sensitive insulating barrier outward, the mutually stranded formation insulation of the two elastic alloy conductors temperature-sensing element of parcel temperature-sensitive insulating barrier, described insulation temperature-sensing element is positioned at skeleton to be arranged in a triangle, and described three eradication edge cores and skeleton are provided with lapping layer, restrictive coating outward successively.
Described high strength temperature-sensitive power cable is characterized in that: described insulation temperature-sensing element is electrically connected with external controller.
The beneficial effects of the utility model:
Temperature-sensing element of the present utility model is arranged in the skeleton, and be electrically connected with external controller, when cable overload or ambient temperature raise the temperature limit that reaches certain, the temperature-sensitive insulating material of temperature-sensing element melts, two elastic alloy conductors short circuit of temperature-sensing element passes to controller with signal, and controller is according to the command adapted thereto action power dump, prevented that cable or equipment are damaged, the anti-extrusion performance of this outer cable is good, mechanical strength is high.
