Abstract
The utility model discloses an optical-fiber composite overhead insulation lead, comprising a twisted composite core arranged in a center, optical fibers mounted in the twisted composite core, twisted conductors covering outside of the twisted composite core and an inner-shielding and insulation sheath extruded outside of the twisted conductors. The composite overhead insulation lead provided by the utility model adopts the multi-strand twisted composite core instead of conventional single composite cores, thereby raising lead bending performance and radial press-resistant stress and increasing safety coefficient.
Description
Technical field
The utility model relates to a kind of optical fiber composite overhead insulated conductor.
Background technology
Along with constantly improving of material science and technology, people just begin to attempt to replace metal material to make the reinforcement core of wire with organic composite material at the end of the nineties in last century, and have obtained certain achievement, have developed the synthetic core wire of advanced composite material (ACM).The synthetic core wire of this advanced composite material (ACM) has been given full play to the speciality of organic composite material, compares with existing various aerial condutors, have lightweight, intensity is large, high temperature resistant, the advantage such as line loss is little, degree of speeding is low.But single composite core also has self inevitable defective, and for example, bending radius is large, limitation and the smooth surface of production specification, all can increase twisted wire and the wire difficulty when construction.Be to increase the fail safe and the wire that a kind of controlling/monitoring and signal transmission are provided of wire, therefore, with a kind of optical fiber composite overhead insulated conductor that good fail safe can transmission information can be arranged again of needs.
The utility model content
The purpose of this utility model is to solve the problem that aforementioned prior art exists, and the high-intensity optical fiber composite overhead insulated conductor that can improve conductive performance and jumbo transmission information and ability to transmit electricity is provided.
The technical scheme that realizes the utility model purpose is a kind of optical fiber composite overhead insulated conductor, comprises the strand type composite core, the optical fiber that is arranged at the strand type composite core that are positioned at the center, is coated on the stranded conductor of strand type composite core outside and extrudes inner shield and insulating sleeve in the stranded conductor outside.
Described strand type composite core is that the compound single core concentric stranding of multiply forms.
Every layer of outside of described strand type composite core is surrounded by non-conductive fibre.
The outside of the outermost layer non-conductive fibre of described strand type composite core is coated with the aluminium lamination that thickness is 0.15 ~ 0.75mm.
Described optical fiber and strand type composite core arbitrary strand of compound single core except the compound single core that is positioned at the center is stranded.
Described stranded conductor can be one or more layers.
Adopted technique scheme, the utlity model has following beneficial effect: (1) the utility model adopts strands type composite core to replace existing single composite core, can improve like this bending property of wire, radially withstand voltage stress, increase coefficient of safety.
(2) strand type composite core of the present utility model all is surrounded by non-conductive fibre outside every layer of composite core; the electrochemical corrosion that can effectively prevent like this aluminium conductor and composite core fiber surface from having potential difference and cause; to playing simultaneously buffer protection function between conductor and the composite core, moreover increase the composite core mantle friction and improve holding of gold utensil and put forth effort.
(3) the utility model is outside outermost non-conductive fibre, namely be coated with aluminium lamination on the face of non-conductive fibre and conductor contact, can effectively increase like this frictional force with conductor, produce not the phenomenon of loosing core by frictional force when preventing and wire payingoff construction stranded at conductor, increase simultaneously conductive section, improve ability to transmit electricity.
(4) because fiber strength is lower, when wire is applied external carbuncle, the suffered stress of middle strand is maximum, and therefore optical fiber of the present utility model twists together with removing one compound single core local official one one composite core that is positioned at the center, can prevent effectively that optical fiber from being broken.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model.
Attached number in the figure is:
Strand type composite core 1, compound single core 11, non-conductive fibre 12, aluminium lamination 13, optical fiber 2, stranded conductor 3, inner shield and insulating sleeve 4.
Embodiment
See Fig. 1, a kind of optical fiber composite overhead insulated conductor of present embodiment comprises the strand type composite core 1, the optical fiber 2 that is arranged at strand type composite core 1 that are positioned at the center, is coated on the stranded conductor 3 of strand type composite core 1 outside and extrudes inner shield and insulating sleeve 4 in stranded conductor 3 outsides.Strand type composite core 1 forms for compound single core 11 concentric strandings of multiply.Every layer of outside of strand type composite core 1 is surrounded by non-conductive fibre 12, be example such as 7 strands among Fig. 1, strand type composite core 1 is divided into two-layer, compound single core 11 at center is one deck, its outer non-conductive fibre 12 that is surrounded by, 6 strands of compound single cores 11 around the outside are another layer, and non-conductive fibre 12 is also arranged outside it, and the outside of this outermost layer non-conductive fibre 12 is coated with the aluminium lamination 13 that thickness is 0.15 ~ 0.75mm simultaneously.The compound single core of optical fiber 2 and the arbitrary thigh of strand type composite core 1 except the compound single core 11 that is positioned at the center 11 is stranded.Stranded conductor 3 can be one or more layers, and conductor can be circle or non-circular structure.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
