UNDERSTANDING OF LOW LOSS CABLE CONSTRUCTION

 

 

 

 

 

CENTER CONDUCTOR

The center conductor is one of Solid Silver Plated Copper Wire or Stranded Silver Plated Copper Wire in accordance with ASTM B-298. The solid center conductor has a less RF resistance, a lower attenuation, and is more amplitude stable with flexure. The stranded center conductor is excellent in flexibility and is more phase stable with flexure.


DIELECTRIC

The Dielectric is composed by Low density Extrusion PTFE with a lower dielectric constant compared with Solid PTFE. Almost of transmission losses are determined by the dielectric material and structure. In addition, the dielectric material and structure determines the velocity of propagation, the using temperature range, the power rating, the phase and amplitude stability, and a flexibility of cable. The LLC-M series cables are constructed by Low Density Extrusion PTFE having low thermal coefficient of expansion, also based on stable and equal pore distribution.


INNER SHIELD

The Inner Shield is composed by Silver Plated Copper Strip wrapped helically between layers. This shield structure provide the outstanding flexibility with providing 100 % coverage rate. The uniform impedance and ideal contact between individual layers of the shield are achieved by unique structure of Silver Plated Copper Strip wrapping.


OUTER SHIELD

The Silver Plated Copper Wire in accordance of ASTM B-298 is braided tightly over the inner shield. The braiding structure provide the tightness of inner shield and also present the additional shield effectiveness.


OUTER JACKET

The FEP ( Fluorinated Ethylene Propylene ) as the material of outer jacket have the strong resistance to Temperature and Chemical.
