Description
Technical Field
The utility model belongs to the technical field of the optic fibre is made, especially, relate to a compound overhead earth wire of insulating type optic fibre.
Background
An existing multi-core optical fiber composite overhead ground wire comprises an optical unit, a first stranded wire layer and a second stranded wire layer, wherein the first stranded wire layer and the second stranded wire layer are stranded outside the optical unit, the first stranded wire layer is 7 aluminum-clad steel wires, and the second stranded wire layer is 12 aluminum alloy wires. The multi-core optical fiber composite overhead ground wire has the advantages that the optical units with large diameters are arranged, the number of the accommodated optical fibers is increased, but the tightness of the structure is not high, and the insulation type, the air tightness and the waterproof performance are not good, so that the line loss can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem and providing an insulating type optical fiber composite overhead ground wire to the realization has the cable structure that the compactness of less diameter is high, and insulating type is good. In order to achieve the above purpose, the utility model discloses technical scheme as follows:
insulating type optical fiber composite overhead ground wire, including central aluminium package copper wire, strand in the outside outer aluminium package copper wire of central aluminium package copper wire, including the insulating layer of the outer aluminium package copper wire of sealing, the insulating layer is made for the HDPE material, and the periphery cross-section of insulating layer is circular structure, and the position between each light unit on the outer aluminium package steel wire is filled to the inside of insulating layer.
Specifically, the central aluminum-clad steel wire and the outer aluminum-clad steel wire are both composed of optical units, and each optical unit comprises a stainless steel pipe and optical fibers filled in the stainless steel pipe.
Specifically, the outer layer of aluminum-clad steel wires is formed by twisting 6 optical units.
Specifically, the cross section of the light unit is of a circular structure, and a gap is reserved between the central aluminum clad steel wire and the outer layer aluminum clad steel wire.
Compared with the prior art, the utility model discloses compound overhead earth wire of insulating type optic fibre's beneficial effect mainly embodies:
the compactness of the whole structure of the cable is improved, and the insulativity, the air tightness and the waterproofness are improved; under the condition of the same mechanical performance and electrical performance, the cable has a smaller outer diameter, has better sag compared with the traditional cable, can directly enter a machine room after falling to the ground, and saves construction cost and time; due to the wrapping and sealing performance of the insulating layer, the loss of the circuit is reduced, and the utilization rate is improved.
