Abstract
The invention provides a one-step formed five-core overhead cable, comprising a body, cable cores and connecting layers, wherein the body has a square structure, a cable core is respectively arranged at four corners of the body, a cable core is arranged in the center of the body, and a connecting layer is arranged between two adjacent cable cores. The production process of the cable is simple, and the cable is convenient to manufacture; a plastic extrusion mode replaces all processes after the cable is formed, so that the production process is greatly shortened, the production cost is lowered, a large amount of raw materials are saved, and the weight of the cable is effectively controlled; and the cable is convenient in use, construction and laying, and greatly reduces the wiring cost.
Description
Technical field
The present invention relates to electricity, the essential electronic element that metal wire or metal tape are made, espespecially one-time formed five core framvesEmpty cable.
Background technology
Five-core cable is exactly the heart yearn of five mutually insulateds, its outside have again parcel these five heart yearns plastic sheath orSteel armour adds plastic sheath, includes five core conductors that are equipped with insulating barrier, is provided with an outer jacket, its outside each core conductorIn a core conductor be that cross section is rounded, circular, the structure of flat, other four core conductors are the structure that cross section is corrugated, shouldThe outside of corrugated is circular arc, and inner edge is straight line, and the core conductor that four cross sections are corrugated is in mode inwardly of inner edge and distributeIn the periphery of the rounded core conductor in described cross section, and fill out and be provided with filler between each core conductor.
The common employing four of five-core cable of prior art adds the structure of a core, is provided with filler, so between cable coreAfter carry out stranding packaging, cause cable quality weight, lay difficulty, stringing cost is high.
Summary of the invention
The invention provides one-time formed five core aerial cables for the problems referred to above, this product processes is simple, systemFacilitate, use the mode of plastic extrusion to replace the later all techniques of stranding, shortened greatly production technology, reduce and produceCost, saves a large amount of raw material, the effectively weight of control cables, easy to use, construct convenient, laying convenience, greatly jointApproximately stringing cost.
For addressing the above problem, the invention provides one-time formed five core aerial cables, comprise body, cable core, connectsConnect layer, it is characterized in that: body is square structure, four angles of body are respectively arranged with cable core, body centerBe provided with a cable core, between two adjacent cables core, be provided with articulamentum.
As a further improvement on the present invention, described cable core is disposed with conductor, lapping layer, polychlorostyrene second from inside to outsideAlkene layer, armouring wire, silastic-layer.
As a further improvement on the present invention, the articulamentum between four cables core of described body exterior is outer surface settingThere is the arcuate structure of automatic cleaning coating.
As a further improvement on the present invention, described body middle part is provided with ring support, ring support and articulamentumJunction is provided with strengthening core.
As a further improvement on the present invention, described articulamentum is crosslinked polyethylene layer.
As a further improvement on the present invention, described ring support is polypropylene support.
Operation principle:
Product of the present invention is provided with rational layout designs, can effectively reduce the processing technology of five-core cable, by onceProperty expressing technique with regard to stranding, effectively shorten the technological process of production of cable, effectively reduced processing cost, save a large amount ofStringing cost, improved the tensile property of product, and improved the qualification rate of product, proof voltage, the stretch-proof of product, prolongMalleability is improved, and the employing of crosslinked polyethylene simultaneously can effectively improve the fire resistance of cable.
The present invention compared with prior art has following beneficial effect:
