Technical field

The present invention relates to field of cable technology, specially a kind of high-low temperature resistant signal cable made of composite material.

Background technique

Cable: being usually by several or several groups of conducting wires form.Define 1: by the conductor of one or more mutually insulated and outer Packet insulating protective layer is made, and electric power or information are transferred to the conducting wire at another place from one.It defines 2: being usually by several or several The cable of similar rope that group conducting wire (every group at least two) is twisted, mutually insulated between every group of conducting wire, and often around A piece center is twisted into, and entire outside is surrounded by the coating of high-insulation.Cable has interior energization, the feature of external insulation.

Cable has power cable, control cable, compensating cable, shielded cable, high-temperature cable, computer cable, signal electricity Cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc..They are led by sub-thread or multiply Line and insulating layer composition, for connecting circuit, electric appliance etc..

With the rapid development of imbedded power cable laying work, to the requirements at the higher level that cable protection proposes, cable protection Casing be using polythene PE and high-quality steel pipe by the pre-treatment of sandblasting ball blast, leaching modeling or coating, the production of heating cure technique and At.It is a kind of protection most common electric insulating tube of electric wire and cable.Because have insulation performance is good, chemical stability is high, Non-corrosive, is suitable for harsh environment and is applied extensively not aging.

Can achieve following advantage using cable protective sleeve protection of pipe cable: 1, good corrosion-resistant, long service life can It is used in moist salt-soda soil band.2, fire-retardant, heat-resist, it can be used for a long time under 130 degree of high temperature and indeformable, it is non-ignitable to meet fire It burns.3, intensity is high, rigidity is high.Direct-burried, can the fast cable work construction progress of roller without adding concrete cover under runway. 4, cable protecting sleeve either tubing or pipe fitting all has certain flexibility, can resist caused by extraneous weight and foundation settlement Destruction.5, there is good anti-outer signals jamming performance.6, inner wall smooth does not scratch cable.Design is using spigot-and-socket Connection type facilitates installation to connect.Joint adds rubber seal envelope not only to adapt to expand with heat and contract with cold, but also prevents silt particle from entering.

Composite material is that people form material component optimum organization of different nature with advanced material preparation technology New material.The composite material generally defined need to meet the following conditions: (i) composite material must be artificial, be people according to The material for needing to manufacture and design;(ii) the material group that composite material must be different by two or more chemistry, physical property Point, it is formed with designed form, ratio, distributed combination, with the presence of apparent interface between each component;(iii) it has knot Structure designability can carry out composite structural design;(iv) composite material not only keeps the advantages of each component material property, Er Qietong Cross the complementation of each component performance and being associated with can obtain single composition material inaccessiable comprehensive performance.The base of composite material Body material is divided into metal and nonmetallic two major classes.There are commonly aluminium, magnesium, copper, titanium and its alloys for metallic matrix.Nonmetal basal body master There are synthetic resin, rubber, ceramics, graphite, carbon etc..Reinforcing material mainly has glass fibre, carbon fiber, boron fibre, aramid fiber fine Dimension, silicon carbide fibre, asbestos fibre, whisker, metal.Silk and hard particulates etc..
