Description

Overhead insulated cable

Technical Field

The utility model belongs to the technical field of the cable, especially, relate to an overhead insulated cable.

Background

The overhead cable, named overhead insulating cable, is overhead conductor with insulating layer and protecting sheath, and is one special cable produced through cross-linked cable producing process and in new power transmission mode between overhead conductor and underground cable. But the current aerial cable has certain defects in use, has poor tensile property, does not meet the requirement of aerial laying, is easy to crack after long-term use, and has poor pressure-bearing capacity.

SUMMERY OF THE UTILITY MODEL

Aiming at solving the problems of the defects and the shortcomings of the prior art; the utility model aims at providing an overhead insulated cable which has simple structure, reasonable design and convenient use, and separates each cable core to avoid mutual interference; and the inside trident support frame can guarantee that the cable is whole to be stereotyped, avoids pressing and leads to inside damaged.

In order to achieve the above object, the utility model adopts the following technical scheme: the cable comprises a three-fork type support frame, a middle inserting groove, a cable core, an inner insulating protective sleeve, insulating filling, an inner rubber protective layer, an aluminum stranded wire and an outer protective sleeve; cable cores are arranged in each separation groove of the three-fork type support frame, a circle of inner insulation protective sleeve is arranged on the outer side of each cable core, and insulation filling is filled between each cable core and each separation groove of the three-fork type support frame; a circle of inner rubber protective layer is arranged on the outer side of the three-fork type supporting frame; the outside parcel of interior rubber protective layer has round aluminum stranded conductor, and the outside parcel of aluminum stranded conductor has outer lag.

Preferably, a hollow groove is formed in the middle of the three-fork type supporting frame, and a grounding wire is inserted into the hollow groove.

Preferably, the outer side of the aluminum stranded wire is sleeved with fastening ferrules at equal intervals.

Preferably, the outer protective sleeve is fused with the aluminum stranded wire in a thermoplastic mode.

Preferably, the inner rubber protective layer and the outer protective sleeve are kept at the same thickness.

After the structure is adopted, the utility model discloses beneficial effect does: the cable core is separated, so that mutual interference is avoided; and the inside trident support frame can guarantee that the cable is whole to be stereotyped, avoids pressing and leads to inside damaged.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and/or process steps that are closely related to the solution according to the invention are shown in the drawings, while other details that are not relevant to the invention are omitted.

Referring to fig. 1 and 2, the following technical solutions are adopted in the present embodiment: the cable comprises a three-fork type support frame 1, a middle inserting groove 2, a cable core 3, an inner insulating protective sleeve 4, insulating filling 5, an inner rubber protective layer 6, an aluminum stranded wire 7 and an outer protective sleeve 8; a cable core 3 is arranged in each separation groove of the three-fork type support frame 1, a circle of inner insulation protective sleeve 4 is arranged outside the cable core 3, and insulation filling 5 is filled between the cable core 3 and the separation groove of the three-fork type support frame 1; a circle of inner rubber protective layer 6 is arranged on the outer side of the three-fork type supporting frame 1; the outside parcel of interior rubber protective layer 6 has round aluminum stranded conductor 7, and the outside parcel of aluminum stranded conductor 7 has outer lag 8.

Wherein, a hollow groove is arranged in the middle of the three-fork type support frame 1, and a grounding wire is inserted in the hollow groove; fastening ferrules are sleeved on the outer sides of the aluminum stranded wires 7 at equal intervals; the outer protective sleeve 8 is fused with the aluminum stranded wire 7 in a thermoplastic mode; the inner rubber protective layer 6 and the outer protective sleeve 8 keep the same thickness.

The working principle of the specific embodiment is as follows: the three-fork type support frame 1 separates the wire cores in the cable, so that the wire cores are kept in an independent state and cannot interfere with each other; and the position is limited under the accompanied of the insulation filling 5; and the outer side of the isolation wire core is wrapped with a circle of aluminum stranded wire protective layer, so that the cable can be effectively prevented from being subjected to compression denaturation.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
