Abstract:
A data cable includes conductors and a filler material substantially surrounding the conductors. The filler material includes a foam filler and a water blocking material. The data cable can also include insulation substantially surrounding each conductor, foam substantially surrounding each conductor, or a solid coating substantially surrounding each conductor. The data cable can further include a shielding member substantially surrounding the filler material or a jacket substantially surrounding the filler material.
Abstract:
The invention relates to a method for protecting a vehicle cabling (1) in a vehicle, said vehicle cabling (1) comprising one or more cables (3) housed within a protective tube (2). The method is particularly characterized in that a longitudinal filling-element (6) comprising an expandable foam-material is inserted into the protective tube (2) adjacent to the cables (3), in a substantially unexpanded state, and that said filling-element (6) is then expanded within the protective tube (2) by supplying heat in such a way that the remaining space in the protective tube (2) is at least partially filled. The invention further relates to a protection device for a vehicle cabling (1), comprising one or more cables (3) housed within a protective tube (2), which protection device is particularly characterized in that a longitudinal filling-element (6) comprising an expandable foam-material is arranged adjacent to the cables (3) within the protective tube (2), said filling-element (6) being adapted to be transformed from a first, substantially unexpanded state to a second expanded state, in which expanded state the filling-element at least partially fills the remaining space within the protective tube (2).

Abstract:
This invention provides a foam barrier which prevents substantial migration of plasticizer from a plasticized polymeric article, such as a PVC cable jacket, into a gel sealing material in contact with the article and prevents substantial migration of oil from the gel material into the article while not significantly interfering with the sealing contact between the gel material and the surface of the article.
Abstract:
Electrical cable with cellular insulating material forming at the same time a sealing sheath. The insulating material is comprised of vinyl poly-chloride expanded up to a percentage by volume of closed pores of 20 to 40% by addition of very fine grains of a chemical expansion agent of a decomposition point comprised between 180 and 200 C. Application to cables for low or medium voltage.
