Description
Technical field
The utility model relates to built on stilts parallel cluster insulated conductor, specifically the built on stilts parallel set rope insulated conductor of low pressure of microtubule for a kind of preset air-blowing optical cable.
Background technology
The power supply mode of urban distribution network (city net) and rural power grids (rural power grids) is 380/220V three-phase four-wire system, be that each elemental user point all can obtain three phase mains, the built on stilts parallel set rope insulated conductor that meets this requirement be national grid city net and rural power grids are newly-built or reconstruction project in the new product applied of emphasis. So-called built on stilts parallel insulation wire refers to the parallel pencil cable forming of aerial condutor by many mutual insulatings, and compared with other wires, parallel set rope wire has wastage reducing and energy saving, protection against electric shock, anti-electricity-theft, easy construction and the advantage such as succinct neat.

Preferably, described dowel is identical with the material of insulating sheath, and described conductive unit, insulating sheath, dowel and air-blowing optical cable microtubule are extruded with a mold one-shot forming.
Preset air-blowing optical cable microtubule in the dowel of the built on stilts parallel set rope insulated conductor of above-mentioned low pressure, has reserved the pipeline that lays air-blowing optical cable, and it can be installed with conventional method by electrical network requirement and be connected built on stilts parallel set rope insulated conductor.
If electrical network and the construction of light net are synchronously carried out, first microtubule is coupled together (reducing fibre-optical splice) not needing to do fibre-optical splice place with special microtube joint as far as possible, then in microtubule, lay micro-cable (micro optical cable) of required fiber type and core number according to the configuration of light net by air-blowing technique.
If light net is built rear, first connect microtubule with special plug by microtubule faces end head plugging or with special joint, can in microtubule, lay in the later stage micro-cable of required fiber type and core number by air-blowing technique according to the configuration of light net.
The utility model has the advantages that: 1, in the dowel of conductive unit, insert air-blowing optical cable microtubule, can require to lay flexibly required optical fiber model and core number according to light net, reduced fibre-optical splice quantity, improved light net transmission quality and reliability. 2, conductive unit separates with light unit, and the operation and maintenance of electrical network and light net is independent of each other, also for upgrading and the expansion of light net provide flexibility. 3, the profile that does not change built on stilts parallel set rope wire, available conventional gold utensil and annex are installed.
