A polymer composition includes a crosslinked polyolefin with improved DC electrical properties. Prior to crosslinking, the polymer composition includes a polyolefin and peroxide, in which the peroxide is in an amount of less than 35 mmol &#x2014;O&#x2014;O&#x2014; per kilogram of the polymer composition. A cable can be surrounded by at least one layer including the polymer composition.

Crosslinkable polymer composition and cable with advantageous electrical properties

A cross-linked polymer composition includes a cross-linked polyolefin. Peroxide in an amount of less than 35 mmol &#x2014;O&#x2014;O&#x2014;/kg polymer composition may be included in the polymer composition prior to crosslinking the polyolefin. Suitable polyolefins that can be cross-linked in the polymer composition include an unsaturated LDPE homopolymer and an unsaturated LDPE copolymer of ethylene with one or more comonomers. Such unsaturated LDPE polymer can contain vinyl groups, and the total amount of vinyl groups present in the unsaturated LDPE can be higher than 0.05/1000 carbon atoms. The cross-linked polymer composition can be used, for example, in producing a cross-linkable and cross-linked article such as a cross-linkable and cross-linked direct current (DC) or other type of power cable.

The invention relates to a use of a polymer composition with improved DC electrical properties in a power cable layer and to a cable surrounded by at least one layer comprising the polymer composition.

Polymer composition for W and C application with advantageous electrical properties

The present invention relates to a polymer composition suitable for the manufacture of an electrical insulation layer for cables having superior mechanical and electrical properties and being environmentally friendly, to a cable comprising said polymer composition as well as to the use of the polymer composition as an electrical insulation layer in cables.
