Abstract
The utility model relates to a feeder cable-dedicated composite material core. The utility model mainly resolves the problem that the prior cable core has poor corrosion resistance and low tensile strength. The composite material core has the following characteristics: a carbon fiber core (1) is wrapped by a protective glass fiber layer (2) with the thickness of 0.5mm to 1.5mm, and the protective glass fiber layer (2) and the carbon fiber core (1) are integrally solidified and shaped by hot setting resin. The feeder cable-dedicated composite material core is characterized by good corrosion resistance and high tensile strength.
Description
Technical field:
The utility model relates to a kind of power transmission cable core, especially power transmission cable composite core.
Background technology:
Power transmission aluminum stranded wire occupies extremely important status as the carrier that transmits electric power in transmission line, along with the continuous development of material science, new material core twisted wire puts into production use more and more, to adapt to the needs of power transmission line.And at present used new material core twisted wire exists electrochemical corrosion and the low problem of tensile strength between core and aluminium stranded conductor interface owing to the material structure reason, influences the normal operation of transmission line.
The utility model content:
In order to solve the low problem of existing cable core corrosion-resistant and tensile strength, the utility model provides a kind of power transmission cable composite core, and this power transmission cable has good corrosion resistance and the high characteristics of tensile strength with composite core.
The technical solution of the utility model is: this power transmission cable comprises core body with composite core, the external 0.5-1.5 millimeter glass fibre protective layer that is coated with of carbon fiber core, and glass fibre protective layer and carbon fiber core body are by the thermosetting resin cured one that is shaped into.
The carbon fiber core body of external diameter in the such scheme below 12 millimeters is solid, and the carbon fiber core body of external diameter more than 12 millimeters is hollow, is filled with filler in hollow.
The utlity model has following beneficial effect: this power transmission cable with composite core owing to take such scheme; increase the cable core corrosion resistance by the glass fibre protective layer; in use the glass fibre protective layer also shields to the carbon fiber core body; reduced cost; be hollow by the carbon fiber core body again; and in be filled with filler, thereby increased the tension and the bending strength of cable, improved the transmission performance of cable.
Description of drawings:
Accompanying drawing 1 is the structural representation of the real core of the utility model;
Accompanying drawing 2 is sectional views of the real core of the utility model;
Accompanying drawing 3 is structural representations of the utility model hollow;
Accompanying drawing 4 is sectional views of the utility model hollow.
1-core body 1 among the figure, 2-glass fibre protective layer, 3-filler.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, Fig. 3, shown in Figure 4; this power transmission cable comprises core body 1 with composite core; real core carbon fiber core body 1 or external diameter the hollow carbon fiber core body 1 12 millimeter or more of external diameter below 12 millimeters is coated with 0.5-1.5 millimeter glass fibre protective layer 2; glass fibre protective layer 2 and carbon fiber core body 1 are filled with filler 3 by the thermosetting resin cured one that is shaped in the hollow carbon fiber core body 1 of external diameter more than 12 millimeters.So core body 1 external diameter adopts real core because of sectional area is little below 12 millimeters, core body 1 external diameter is hollow because of the big employing of sectional area more than 12 millimeters, and in be filled with filler 3, thereby improved the resistance to compression and the bending strength of core body 1.Because of core body 1 is coated with glass fibre protective layer 2, thereby the corrosion resistance of core body 1 is improved, thereby guaranteed the transmission performance of power transmission cable.This power transmission cable has good corrosion resistance and the high characteristics of tensile strength with composite core thus.
Claims (2)
