Data communication cables include twisted wire pairs, a fire retardant tape, a metallized tape shield, a braided metallic shield, and a jacket layer. The fire retardant tape surrounds the twisted wire pairs has an overlap of about 15% to about 25%. The data communication cables are also halogen-free and may pass the fire retardant standards of National Fire Protection Agency (“NFPA”) 130.

Provided is a power cable, and more particularly, to an ultra-high-voltage underground or submarine cable. In detail, the present invention relates to a power cable which is capable of effectively preventing a decrease in dielectric strength due to penetration of copper powder from a copper conductor into an insulating layer, thereby increasing the lifespan thereof, is capable of preventing damage to insulating paper, semiconductor paper, etc. even when repeatedly bent and unfolded, thereby maintaining an interlayer structure formed by winding the insulating paper, the semiconductor paper, etc., and is capable of improving bendability, flexibility, installability, workability, etc.

A cable includes a center conductor and at least one layer formed of silicon dioxide fibers that are braided around the center conductor to form a braided dielectric core layer over the center conductor. An outer conductor layer is formed over the braided silicon dioxide core layer either as a wrapped tape or a semi-rigid conductor. In flexible embodiments of the cable, one or more outer strength layers and jackets may be applied over the outer conductor layer. In embodiments of the invention, the dielectric core layer includes at a plurality of sublayers of silicon dioxide fibers wherein each of the sublayers is successively braided on a previous sublayer.

A method for producing a thermal insulating paper includes producing the thermal insulating paper in a classic paper production process from a raw material having materials with good thermal properties and materials with electrically insulating properties in a paper matrix. A thermal insulating paper produced using the above method may include inorganic fibers, electrical insulators, aramid fibers, or binders.

A paper suitable for use in a battery or battery pack as a flame barrier or thermal insulation, the paper comprising 60 to 95 weight percent aerogel powder and 5 to 40 weight aramid polymer fibrils; the paper having a thickness of 50 to 4000 micrometers.

The invention relates to a cable wrapping tape for wrapping cables in motor vehicles, comprising a tape-shaped carrier and an adhesive coating on at least one side of said carrier, and characterised in that the adhesive coating and/or carrier are provided with an incorporated repellent against, in particular, mammal bites.

An adhesive tape is made by hot calendering a substrate between two generally identical rolls one of which is heated to a different temperature than the other roll while rotating the rolls at the same peripheral speed to flatten one face of the substrate and reduce air permeability of the substrate by at least 15%. Then an adhesive coating is applied to at least one of the faces of the substrate.

An electrical transmission line cable suited for a variety of applications, including as a fishing line in a video fishing system. The electrical transmission line cable has a first conductor and a second conductor forming an electrical transmission line; a jacket containing the first conductor and the second conductor; and a transmission line primary dielectric element separating the first conductor and the second conductor, wherein the primary dielectric element is at least one of textile yarns, fiber yarns, or monofilaments. The electrical transmission line may be in a balanced configuration or an unbalanced configuration.
