Description
Technical field
The present invention relates to protect pipe field, particularly relate to a kind of low-temperature resistance type optical cable protective tube.
Background technology
Along with development and the progress of science of society, the safety of information transmission is more and more important.Wherein optical cable is information
Transmit one of of paramount importance medium, and the protection for optical cable is increasingly subject to people's attention.
But existing optical cable protective tube is generally the most sensitive to temperature, and low temperature resistivity is poor, in the face of extreme natural ring
Optical cable cannot be played the effect of being effectively protected by border, is easily reduced the efficiency of transmission of optical cable, even damages optical cable.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of low-temperature resistance type optical cable protective tube, by using outside body
Portion and die internal are respectively provided with external thermal insulation and inner thermal insulating layer, and the low-temperature resistance effect of optical cable protective tube has been significantly greatly increased, tool
Have that novel structure, low-temperature resistance be effective, length in service life, the advantage such as convenient and practical, universal at low-temperature resistance type optical cable protective tube
On have market prospect widely.
For solving above-mentioned technical problem, the present invention provides a kind of low-temperature resistance type optical cable protective tube, including: body, tube core, outer
Heat-insulation layer and inner thermal insulating layer, described tube core is uniformly built in the inner surface of described body, described in described external thermal insulation uniform fold
The outer surface of body, the inner surface of tube core described in described inner thermal insulating layer uniform fold, the material of described body is glass fibre, institute
The material stating external thermal insulation is polystyrene foam plastics, and the material of described inner thermal insulating layer is nano ceramics microballon.
In a preferred embodiment of the present invention, the thickness of described external thermal insulation is more than the thickness of described inner thermal insulating layer.
In a preferred embodiment of the present invention, the thickness of described external thermal insulation is less than the thickness of described body with described tube core
Degree sum.
In a preferred embodiment of the present invention, the thickness of described inner thermal insulating layer is less than 0.5mm.
The invention has the beneficial effects as follows: low-temperature resistance type optical cable protective tube of the present invention have novel structure, low-temperature resistance effective,
Service life length, the advantage such as convenient and practical, low-temperature resistance type optical cable protective tube universal on have market prospect widely.
