Abstract
The utility model belongs to the wire appliance technical filed and especially relates to a steel band armoured shielding telephone line. The steel band armoured shielding telephone line comprises a conductor wrapped by a foaming polyethylene insulating layer and is characterized in that the foaming polyethylene insulating layer is covered by a polyester film which is covered by a sheath; the sheath is covered by a steel band armor layer. The steel band armoured shielding telephone line can prevent a telephone line from mechanical damage in laying or operation processes to ensure integrity of an inner jacket.
Description
Technical field
The utility model belongs to electric wire apparatus technical field, relates in particular to a kind of steel-tape armouring shielding telephone wire.
Background technology
Along with the development of present society, communication more and more seems important.Telephone wire is as apparatus the most common in the communications industry, and the field of use is also the most widely.General telephone wire all is comprised of some phone heart yearns, then externally superscribes one deck aluminium foil as anti-tampering use.This type of telephone wire has certain anti-tampering effect due to the aluminium foil of outside.But this type of telephone wire is subjected to mechanical damage in laid processes or running, thereby has destroyed inner conductor.And due to the environment variation of telephone wire outside, make telephone wire comparatively easily be corroded, thereby make shorten the service time of telephone wire.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of steel-tape armouring shielding telephone wire is provided, and its technical scheme is as follows:
A kind of steel-tape armouring shielding telephone wire, comprise conductor, the outer wrap of described conductor has the polyethylene foamed insulating barrier, it is characterized in that, the outside of described polyethylene foamed insulating barrier is provided with one deck polyester film, the outside of described polyester film is provided with sheath, and described sheath outer wrap has the steel-tape armouring layer.
Optimal way is that described sheath is leadless polyvinyl chloride sheath or non-dividing a word with a hyphen at the end of a line property pvc sheath.
Optimal way is that described conductor is tin-coated copper or naked copper.
The steel-tape armouring shielding telephone wire that the utility model provides, when in use, the outer wrap of conductor has the polyethylene foamed insulating barrier, can be good at conductor is played the effect of insulation, has well prevented the loss of electric power.And be provided with one deck polyester film in the outside of polyethylene foamed insulating barrier, and can play shielding action preferably, make the transmission of conductor information avoid being interfered.The outside of described polyester film is provided with sheath, and described sheath outer wrap has the steel-tape armouring layer.Sheath and steel-tape armouring layer can be good at polyester film and conductor are played the effect of protection.
Sheath described in the utility model is leadless polyvinyl chloride sheath or non-dividing a word with a hyphen at the end of a line property pvc sheath.Make sheath have preferably performance polyester film is protected, make the effect of protection reach best effect.
Conductor described in the utility model is tin-coated copper or naked copper.Can make better good of the effect of conductor transmission, better clear and complete of the information of transmission.
The utility model can prevent the mechanical damage that telephone wire is subjected in laid processes or running, to guarantee the integrality of sheath.The steel-tape armouring layer mainly forms (we adopt steel band) by steel band or steel wire simultaneously, and (being coated with) all plated on their surface lumarith, thus certain corrosion resisting property is arranged, thus extend the useful life of telephone wire.Telephone wire can bear certain pressure after steel-tape armouring, therefore the telephone wire of steel-tape armouring can directly buried installation.

Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of steel-tape armouring shielding telephone wire, comprise conductor 1, the outer wrap of described conductor 1 has polyethylene foamed insulating barrier 2, it is characterized in that, the outside of described polyethylene foamed insulating barrier 2 is provided with one deck polyester film 3, the outside of described polyester film 3 is provided with sheath 4, and described sheath 4 outer wrap have steel-tape armouring layer 5.
Optimal way is that described sheath is leadless polyvinyl chloride sheath or non-dividing a word with a hyphen at the end of a line property pvc sheath.
Optimal way is that described conductor is tin-coated copper or naked copper.
The steel-tape armouring shielding telephone wire that the utility model provides, when in use, the outer wrap of conductor has the polyethylene foamed insulating barrier, can be good at conductor is played the effect of insulation, has well prevented the loss of electric power.And be provided with one deck polyester film in the outside of polyethylene foamed insulating barrier, and can play shielding action preferably, make the transmission of conductor information avoid being interfered.The outside of described polyester film is provided with sheath, and described sheath outer wrap has the steel-tape armouring layer.Sheath and steel-tape armouring layer can be good at polyester film and conductor are played the effect of protection.
