SDGFV(Y)-75 TYPE polythene physical high-froth cable

PRODUCT INTRODUCTION
SDGFV(Y)-75 TYPE polythene physical high-foam cable has low medium loss injecting gas enable medium has foam, then very little mutual sealing gas holes appear through selecting proper technical parameters. This kind of medium is not easy to be aging and moisture.
The inner conductor is purple copper wire, while the outer one is Aluminum pipe or Aluminum and plastic belt adding tin-plated copper wire weaving. Because the medium and inner conductor are combined tightly, relative movement won't appear between them.

Compared with other radio frequency cable of a same size, SDGFV(Y)-75 TYPE cable has a less attenuation transmitting high frequency signal and ultra-high frequency signal, it is applied to CAT and closed circuit television system. Its parameters have reached the international standard of radio frequency cable.
