Background
The overhead cable (called overhead insulated cable) is an overhead conductor with insulating layer and protective sheath, and is a special cable made up by adopting the similar production process of cross-linked cable, and is a new power transmission mode between overhead conductor and underground cable. The aerial cable is a single core, and can be divided into a duralumin wire structure, an aluminum alloy wire structure, a steel core or aluminum alloy core supporting structure, a self-supporting three-core threaded structure (the wire core can be duralumin or duralumin wire) and the like according to different structures. The power supply system has the main characteristics of high power supply reliability, good power supply safety, convenience in erection and maintenance, reasonable economy and the like. The main technical parameters comprise weather resistance, insulation level, inner and outer semi-conductive shielding layers. The overhead cable has wide transmission application at home and abroad. The hard drawn copper wire structure is heavy, but the pulling force is large, the capacity of resisting the action of external force is strong, and even the cable can still be electrified when the tower is broken. The aluminum alloy wire structure is light in weight and large in tension, and is mainly used in a large-span tower system with the span of 100 m. The steel core or aluminum alloy core supporting structure is generally used for a 35kV voltage system, the span is large, a supporting wire (bare wire) and three insulated phase lines are separated by a square insulating piece, the supporting wire can be used as a lightning conductor, and the steel core or aluminum alloy core supporting structure has the greatest advantages of small sag and arc weight of only about 2.4% of the span. The self-supporting three-core stranded structure is used in a system with medium span, and the cable has the following disadvantages: the three-core cable is shorter in length and more in joints than a single core cable, and is provided with an outer semi-conductive shielding layer, and a terminal or a stress cone structure is arranged at the tail end of the cable like a common cable.
The existing overhead cable inner core is easily twisted together in a staggered manner, so that the existing overhead cable inner core is inconvenient to flush and place quickly and neatly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an inner core spacer for aerial cable to the problem of flushing putting of inconvenient quick neatly when putting is carried out to the aerial cable inner core that proposes among the above-mentioned background art.

Preferably, the four ends of the positioning sheet main body are both provided with avoiding grooves, and the avoiding grooves and the inner core positioning grooves are staggered.
Preferably, the positioning sheet main body is internally provided with a reinforcing inner hole, and the axis of the reinforcing inner hole coincides with the axis of the positioning sheet main body.
Preferably, the connecting side holes are formed in the four sides of the positioning sheet main body, and the connecting side holes are communicated with the reinforcing inner hole and the inner core positioning groove.
Preferably, the axes of the reinforced inner holes on the four sides of the positioning sheet main body and the axes of the corresponding inner core positioning grooves are perpendicular to each other and are positioned in the same plane.
Compared with the prior art, the beneficial effects of the utility model are that: this inner core spacer for aerial cable can be quick with the neat putting together of leveling of aerial cable inner core, convenient follow-up processing improves and puts efficiency. This inner core spacer for aerial cable can fix a position the aerial cable inner core through the semi-circular inner core positioning groove of four sides of spacer main part, and can consolidate the position of aerial cable inner core through the fixed glue film, improves the installation stability of aerial cable inner core.
