Abstract
The invention provides an environment-friendly one-core aerial cable formed for one time. The environment-friendly one-core aerial cable comprises a conductor, a shell, a crosslinked polyethylene layer and through holes, wherein the crosslinked polyethylene layer is arranged on the outside surface of the conductor; a water-blocking tape is arranged in the crosslinked polyethylene layer; a plurality of connection blocks are arranged outside the crosslinked polyethylene layer; the shell is arranged at the outer ends of the connection blocks; a plurality of cavities are arranged between the crosslinked polyethylene layer and the shell; and the plurality of through holes are arranged on the shell corresponding to the cavities. The environment-friendly one-core aerial cable is simple in production process and convenient to manufacture; all processes after cabling are replaced by using a plastic extrusion manner; by means of combined design of the crosslinked polyethylene layer and the shell, heat generated by the cable can be effectively conducted in an external environment; and security incidents due to the fact that the internal part of the cable is too hot can be effectively prevented.
Description
Technical field
The present invention relates to the essential electronic element that electricity, metal wire or metal tape make, espespecially one-time formed environmental protection one core aerial cable。
Background technology
Electric wire can in order to transmit electricity (magnetic), information and the wire product realizing electromagnetic energy conversion, the electric wire of broad sense is also referred to simply as cable, the cable of narrow sense refers to insulated cable, it may be defined as, the aggregation being made up of following part, one or more insulated wire cores, and the clad that each of which is likely to be of, total protective layer and outer jacket, cable also can have the additional conductor not having insulation, can in order to transmit electricity (magnetic), information and the wire product realizing electromagnetic energy conversion, the electric wire of broad sense is also referred to simply as cable, the cable of narrow sense refers to insulated cable, it may be defined as, the aggregation being made up of following part, one or more insulated wire cores, and the clad that each of which is likely to be of, total protective layer and outer jacket, cable also can have the additional conductor not having insulation, along with electric power, the development of energy industry, various cables apply to the every field of productive life more and more, and generally all imbed underground or entrance cable duct lays。
Mostly contribute to transmission electric power due to cable, owing to cable can generate heat unavoidably in transmission power process, how the heat that cable produces is exported to the difficult problem being always up industry in external environment condition。
Summary of the invention
One-time formed environmental protection one core aerial cable is the invention provides for the problems referred to above, this product processes is simple, easy to make, the mode using plastic extrusion replaces all techniques that stranding is later, modular design by cross-linked polyethylene layer Yu shell, can effectively heat produced by cable conductor be exported in external environment condition, effectively prevent cable over-heat inside from security incident occurring。
For solving the problems referred to above, the invention provides one-time formed environmental protection one core aerial cable, including conductor, shell, cross-linked polyethylene layer, through hole, it is characterised in that: conductor outside surfaces is provided with cross-linked polyethylene layer, and cross-linked polyethylene layer is internally provided with waterstop, some contiguous blocks it are provided with outside cross-linked polyethylene layer, contiguous block outer end is provided with shell, is provided with some cavitys between cross-linked polyethylene layer and shell, and the shell that cavity is corresponding is provided with some through holes。
As a further improvement on the present invention, described contiguous block is provided with steel wire with the junction of shell。
