Abstract
The invention discloses an aging resistant tensile telephone line comprising two core wires, inner insulating layers wrapping the core wires and an external insulating layer wrapping the inner insulating layers. The external insulation layer is an ethylene-propylene-diene monomer layer. The thickness of the ethylene-propylene-diene monomer layer is 0.2-0.5mm. Nylon wires are arranged inside the external insulating layer. The inner insulating layer is composed of polyethylene layers wrapping the core wires and aluminium foils wrapping the polyethylene layers. According to the invention, through the arrangement of the nylon wires inside the telephone line, the tensile capability of the telephone line can be substantially improved; and the external insulating layer is the ethylene-propylene-diene monomer layer which has superior anti-oxidation, anti-ozone and anti-erosion capabilities, so that problems that the easy aging problem of the telephone line is solved.
Description
Technical field
The invention belongs to electric wire field, be specifically related to a kind of ageing-resistant tension telephone wire.
Background technology
Outdoor telephone wire is owing to exposing to the sun and rain, and is easy to agingly, causes phone usually to break down, and increased maintenance cost.Existing telephone wire tensile strength is lower, when needs large span drags line to install, is easy to line to break.
Along with developing by leaps and bounds of electronic technology, in environment, exist various powerful electromagnetism broken, usually can produce electromagnetic interference to telephone wire, cause the problem that speech quality is not high.
Summary of the invention
The object of the invention is to provide a kind of telephone wire, solves existing telephone wire tensile strength low, easily aging and easily by the problem of electromagnetic interference.
Technical scheme of the present invention is:
A kind of ageing-resistant tension telephone wire, comprise two heart yearns, be coated on inner insulating layer on heart yearn and the external insulation layer of coated inner insulating layer, described external insulation layer is ethylene-propylene-diene monomer glue-line, the thickness of described crosslinked ethylene-propylene-diene monomer glue-line is 0.2-0.5mm, in described external insulation layer, be provided with nylon wire, described inner insulating layer consists of the aluminium foil layer that is coated on the polyethylene layer on heart yearn and be coated on outside polyethylene layer.
The present invention compared with prior art tool has the following advantages:
The present invention by arranging nylon wire in telephone wire, can significantly strengthen the resistance to tension of telephone wire, and its external insulation layer is ethylene-propylene-diene monomer glue-line, it has superior resistance to oxidation, anti-ozone and erosion-resistant ability, thereby has solved easily aging problem of telephone wire.Described inner insulating layer consists of the aluminium foil layer that is coated on the polyethylene layer on heart yearn and be coated on outside polyethylene layer.Can increase the ability of the anti-electromagnetic interference of telephone wire.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of telephone wire of the present invention;
Reference numeral is: 1-heart yearn, 2-inner insulating layer, 3-external insulation layer, 4-nylon wire.
Embodiment
Embodiment
As shown in Figure 1, a kind of telephone wire, comprises two heart yearns 1, is coated on inner insulating layer 2 on heart yearn 1 and the external insulation layer 3 of coated inner insulating layer 2.Described external insulation layer 3 is ethylene-propylene-diene monomer glue-line, when the thickness of ethylene-propylene-diene monomer glue-line is 0.2-0.5mm, not only has good ageing resistance but also have lower cost.In described external insulation layer 3, be provided with nylon wire 4, the quantity of nylon wire 4 is set as required, and described inner insulating layer 2 consists of the aluminium foil layer that is coated on the polyethylene layer on heart yearn and be coated on outside polyethylene layer.So just can well play the effect of anti-electromagnetic interference
The present invention, by nylon wire 4 is set in telephone wire, can significantly strengthen the resistance to tension of telephone wire, and its external insulation layer 3 is ethylene-propylene-diene monomer glue-line, and it has superior resistance to oxidation, anti-ozone and erosion-resistant ability.Thereby solved easily aging problem of telephone wire.
