SEALED AND BALANCED HIGH-FREQUENCY CABLE Russian patent published in 2006 - IPC H01B11/02 

FIELD: data transmission under very humid conditions, those including on board ships.

SUBSTANCE: proposed cable has sequentially arranged core incorporating at least two pairs of polyethylene covered stranded conductors, filler in the form of low-molecular rubber based sealing composition, shield, and sheath with mentioned filler in-between. This composition is, essentially, compound incorporating 100 parts by mass of rubber SKTN and 3-5 parts by mass of catalyst; the latter has 7 mass percent of γ-aminopropyl triethoxysilane and 93 mass percent of ethyl silicate; these pairs are placed longitudinally throughout entire cable length inside filler All air gaps are filled up (no water penetrates along cable).

EFFECT: reduced outer diameter at low attenuation constant and high near-end cross-talk attenuation throughout entire operating frequency band.
