Following advantage：1, good corrosion-resistant, service life is long, can be used in moist salt-soda soil band.2, fire-retardant, heat-resist, it can be
It is used for a long time under 130 degree of high temperature and indeformable, meets fire and does not burn.3, intensity is high, rigidity is high.Direct-burried is without adding under runway
Concrete cover, can the fast cable work construction progress of roller.4, cable protecting sleeve either tubing or pipe fitting all has one
Fixed flexibility, can resist the destruction caused by extraneous weight and foundation settlement.5, there is good anti-outer signals jamming performance.6、
Inner wall smooth does not scratch cable.Design facilitates installation to connect using the connection type of spigot-and-socket.Joint adds rubber seal
Envelope not only adapts to expand with heat and contract with cold, but also prevents silt particle from entering.And cable in the prior art in desert region in use, just having very much
Defect is for example：
1. cable in the prior art will produce certain heat when in use, and in desert region in use, extraneous temperature
Degree is high so that and internal temperature is difficult to reduce, and the normal time uses the danger it is possible that fusing, so cannot be satisfied the prior art
It is required.
2. cable in the prior art in desert region in use, the prior art be usually trepanning is carried out on cable, make
Its heat dissipation is quicker, if but there is rainwater in such mode, when it is possible that the case where cable fault occur, and
Hole can be blocked using sand and dust for a long time, to heat dissipation effect that can not be significantly estimated, so cannot be satisfied needed for the prior art.
Utility model content
The purpose of this utility model is to provide a kind of desert region high temperature-resistant cables, to solve in above-mentioned background technology
The problem of proposition.
