Abstract (en)

A filler for a telecommunication cable containing a pre-foamed petrolatum or petroleum jelly with the petrolatum containing an exceptionally high oil content of at least about 40% by weight and the solids content is in the form of fine particulates of less than 100 mu m, and preferably 5 to 10 mu m, dispersed throughout the liquid portion. The cell structure is air-filled, closed-cell, and provides a light-weight cable filler with good electrical insulation properties, particularly a low dielectric constant.
