Description
Technical field
This utility model is related to a kind of underground communication cable.
Background technology
Logical line cable is the electricity for transmitting phone, telegram, fax paper, TV and broadcast program, data and other signals of telecommunication
Cable.Formed by the wire stranding of more than a pair mutually insulateds.Cable core, outside tool are made up of the wire or conductor of many mutual insulatings
There is the communication line of sealing sheath.What is had is also equipped with outer jacket outside sheath.There are built on stilts, direct-burried, pipeline and the bottom etc. various
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 maintenance.Phone, electricity can be transmitted
Report, data and image etc..
Communication cable refers to the electricity of the high frequency carrier and digital communication and signal transmission for low coverage voice communication and long distance
Cable, is one of Chinese five big cable products.According to the purposes and use range of communication cable, six big series of products can be divided into, i.e.,
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 three kinds of traditional cable-type, banding array type and 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, and service life is not long.
Utility model content
