Abstract
The utility model discloses a five-core type gopher protected temperature sensing cable. The cable comprises five conductors. An insulating layer is formed on the outside of each conductor through the extrusion moulding process, the five conductors coated with the insulating layers are twisted by taking a rope-like elastomer having a pentagonal cross section as the center to form the insulated core, and a through hole is formed in the center of the rope-like elastomer. A heat-sensitive insulated layer is formed on the outside of each of two elastic alloy conductors through a heat-sensitive insulated material through the extrusion moulding process, the two elastic alloy conductors coated with the heat-sensitive insulated layers are twisted to form an insulated temperature sensing element, the insulated temperature sensing element is located on the outside of the insulated core to form the cable core, the outside of the cable core is coated with a wrapping layer, a metal pipe and a sheath layer successively, and gopher protected capsules are uniformly distributed in the sheath layer. According to the utility model, the temperature sensing element is arranged outside the insulated core of the cable and electrically connected with an external controller, so the damage on the cable or equipment is prevented. Meanwhile, the metal pipe and the gopher protected capsules are arranged, so the cable will not be damaged by gophers, so that the mechanical performance of the cable can be improved, and a service life of the cable is prolonged.
Description
Technical field
The utility model relates to the power cable field, specifically a kind of five core pattern mouse bite preventing temperature sensing cables.
Background technology
Power cable is in operation and all will be defined under certain ambient temperature, allows power cable by the electric current of limit, determines useful life and the safety of the insulating barrier of power cable.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 tensile strength, the mouse bite preventing hurt of strengthening simultaneously cable badly are the problems that industry is explored always.
The utility model content
The purpose of this utility model provides a kind of five core pattern mouse bite preventing temperature sensing cables, on the basis of common power cable, adds temperature-sensing element, and protection cable or equipment are not compromised, and not damaged by damaged by rats.
The technical solution of the utility model is as follows:
Five core pattern mouse bite preventing temperature sensing cables, include five conductors, it is characterized in that: described five conductors outward respectively extrusion moulding insulating barrier is arranged, five conductors of wrap insulate layer take the cross section as pentagonal rope form elastomer centered by mutually stranded formation insulated wire cores, rope form elastomer center is provided with through hole; There are two elastic alloy conductors to adopt respectively temperature-sensitive insulating material extrusion moulding that the temperature-sensitive insulating barrier is arranged outward, the mutually stranded formation insulation of the two elastic alloy conductors temperature-sensing element of parcel temperature-sensitive insulating barrier, the insulation temperature-sensing element is positioned at the insulated wire cores outside and consists of cable core, cable core is wrapped with lapping layer, metal tube, restrictive coating, is evenly distributed with the capsule of mouse bite preventing in the described restrictive coating.
Described five core pattern mouse bite preventing temperature sensing cables 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 on the cable insulation core outside, and is electrically connected with external controller, has prevented that cable or equipment are damaged; The capsule of while metal tube and mouse bite preventing, so that cable is not damaged by damaged by rats, mechanical performance can get a promotion; Extraneous extruding force is effectively resisted in the elastomeric design of rope form, has prolonged the useful life of cable.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1:
Five core pattern mouse bite preventing temperature sensing cables, include five conductors 1, five conductor 1 outer respectively extrusion moulding have insulation 2, five conductors 1 of wrap insulate layer 2 take the cross section as pentagonal rope form elastomer 3 centered by mutually stranded formation insulated wire cores, rope form elastomer 3 centers are provided with through hole 4; There are two elastic alloy conductors, the 5 outer temperature-sensitive insulating material extrusion moulding that adopt respectively that temperature-sensitive insulating barrier 6 is arranged, two elastic alloy conductors, the 5 mutually stranded formation insulation temperature-sensing elements of parcel temperature-sensitive insulating barrier 6, the insulation temperature-sensing element is positioned at the insulated wire cores outside and consists of cable core, cable core is wrapped with lapping layer 7, metal tube 8, restrictive coating 9, is evenly distributed with the capsule 10 of mouse bite preventing in the restrictive coating 9.
The insulation temperature-sensing element is 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, signal is passed to controller, controller has prevented that according to the command adapted thereto action power dump cable or equipment are damaged.
