Abstract
The utility model discloses an aging resistant tensile telephone line. The aging resistant tensile telephone line comprises two core wires, internal insulating layers coating the core wires, and an external insulating layer coating the internal insulating layers, the external insulating layer is an EPDM rubber layer, the thickness of the cross-linked EPDM rubber layer is 0.2 mm to 0.5 mm, nylon wires are arranged in the external insulating layer, and each internal insulating layer comprises a polyethylene layer coating the core wire and an aluminum foil layer coating the polyethylene layer. According to the aging resistant tensile telephone line, the nylon wires are arranged in the telephone line, the tensile ability of the telephone line is obviously enhanced; and the external insulating layer is the EPDM rubber layer which is advantaged by excellent oxidation resistance, ozone resistance, and erosion resistance so that the problem of easy aging of the telephone line is solved.
Description
Technical field
The utility model belongs to electric wire field, is 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 utility model 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 the utility model telephone wire;
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 utility model, 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.
