Description
Technical field
It the utility model is related to a kind of cable, and in particular to a kind of anti-termite cable of the power system of subway engineering.
Background technology
With China's expanding economy, subway gradually occurs in major, middle city on ground, and air is comparatively in subway tunnel
Humidity, it is more severe in the corner environment of darkness, it sometimes appear that termite and other insects bite to the cable of laying.Mesh
Preceding common rat-and-ant proof cable is all that some noxious materials are added in oversheath, plays a part of killing mouse ant, but be added with
Cable laying for a long time after noxious material has part noxious material and evaporate into air, and the ventilation condition in subway is poor, for a long time
Laying such cable can have an impact to health.
Utility model content
The utility model provides a kind of anti-termite cable of the power system of subway engineering, solves existing ground ferroelectricity
Cable is embedded in underground and easily bitten by insects such as termites, is easily damaged cable, and the cable for scribbling noxious material is long-term use of, and not
The problem of being easy to health.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of anti-termite cable of the power system of subway engineering of the utility model, including cable body, the cable
Several containment vessels are cased with outside body, one end of the containment vessel is provided with connector, external screw thread is provided with outside the connector,
Corresponding internal thread is provided with the inside of the other end of the containment vessel, several described containment vessels pass through screw thread phase between each other
Connection, the cable body internal package have cable core, are arranged with insulating barrier outside the cable core, the insulating barrier is wrapped with filling
Layer, the packed layer are wrapped with fireprotection layer, are also arranged with inner sheath and oversheath outside the fireprotection layer, and the inner sheath and
Flexible pillar armor is wrapped up between oversheath.
As a kind of optimal technical scheme of the present utility model, the fireprotection layer is fire-resistant isinglass belt.
As a kind of optimal technical scheme of the present utility model, the packed layer is polypropylene mesh gasket for packing.
As a kind of optimal technical scheme of the present utility model, the inner sheath and oversheath are that low-smoke non-halogen flame-retardant gathers
Alkene sheath.
As a kind of optimal technical scheme of the present utility model, the insulating barrier is nitrile rubber insulating barrier.
As a kind of optimal technical scheme of the present utility model, the material of the containment vessel is concrete.
The beneficial effect that the utility model is reached is：By increasing containment vessel outside cable, containment vessel uses coagulation
Soil material makes, and termite can be prevented to bite cable, can protect cable；When mounted, it is convenient by former and later two
Containment vessel is connected through a screw thread, and can not only connect fastening, and convenient connection.
Brief description of the drawings
