Description
Technical field
The present invention relates to a kind of underground communication cable.
Background technology
Logical line cable is transmission phone, telegram, the electricity of fax paper, TV and broadcast program, data and other electric signals
Cable.Formed by the wire stranding of more than a pair mutually insulated.Cable core is constituted by the wire or conductor of many mutual insulatings, outside tool
There is the communication line of sealing sheath.Have is also equipped with outer jacket outside sheath.There are built on stilts, direct-burried, pipeline and bottom etc. multiple
System of laying.It is divided into symmetrical, coaxial and composite cable by structure；It is divided into field operation by function and forever for cable（Underground, seabed electricity
Cable）.Communication cable transmission band is wider, and message capacity is larger, little by external interference, but is difficult to overhaul.Phone, electricity can be transmitted
Report, data and image etc..
Communication cable refers to the electricity of high frequency carrier for low coverage voice communication and long distance and digital communication and signal transmission
Cable, is one of Chinese five big cable products.Purposes according to communication cable and range, can be divided into six big series of products, that is,
City communication cable（Including paper insulation city words cable, polyolefin insulation polyolefin jacket city words cable）, long distance symmetric cable（Bag
Include paper insulation low-and high-frequency long distance symmetric cable, copper core foamed polyethylene low-and high-frequency long distance symmetric cable and Digital Transmission long-distance right
Claim cable）, coaxial cable（Including small diameter coaxial cable, in coaxial and small coaxial cable）, submarine cable（Can divide symmetrical seabed and
Coaxial submarine cable）, fiber optic cables（Including traditional cable-type, banding array type and three kinds of matrix type）, radio-frequency cable（Including
Symmetric radio frequency and coaxial radio-frequency）.
Existing communication cable waterproof effect is general at present, does not possess resistance to elevated temperatures, service life is not long.
