Description
Technical field
The present invention relates to cable production field, more particularly to a kind of coaxial cable.
Background technology
Coaxial cable can be divided into two kinds of fundamental types, base band coaxial cable and BBC(broadband coaxial cable).Base band is conventional at present
Cable, its shielding line is to be made with copper netted, and characteristic impedance is 50 (such as RG-8, RG-58)；BBC(broadband coaxial cable) is normal
The screen layer of cable is typically rammed with aluminium, and characteristic impedance is 75 (such as RG-59).
Coaxial cable can be divided into according to its diameter：Thick coaxial cable and thin coaxial cable.Thick cable is applied to compare
Large-scale localized network, its gauged distance length, reliability is high, due to cable need not be cut off during installation, therefore can basis
Need to be adjusted flexibly the networking position of computer, but thick cable network must install transceiver cable, and installation difficulty is big, so overall
Cost is high.On the contrary, cablet installs then fairly simple, low cost, but because installation process will cut off cable, two must be loaded onto substantially
Network connecting head (BNC), is then connected on t connector both ends.
Its surrounding layer of existing coaxial cable is often PE resin-insulated materials, and its damping effect is poor, and uses glass fibre
It is distorted, tensile property is poor, and is that enhancing shield effectiveness uses mesh shields layer made of copper or aluminium, and its is costly, raw
Production is complicated.
