Abstract
A resin composition, including a resin component containing propylene units, and a resistance-imparting agent, wherein the resistance-imparting agent is a monomer having a phenol skeleton with hydrogen or an alkyl group having 1 to 3 carbon atoms, bonded to at least one of ortho positions to the hydroxyl group of the phenol skeleton, and has a melting point of 145° C. or less and a molecular weight of 200 or more and 500 or less, and a content of the resistance-imparting agent is 0.4 parts by mass or more and 10 parts by mass or less with respect to 100 parts by mass of the resin component.
Claims8
A power cable, comprising:
- a conductor, and
- an insulating layer coated on an outer circumference of the conductor,
- wherein the insulating layer is formed from a resin composition,
- the resin composition comprises a resin component containing propylene units, and a resistance-imparting agent,
- the resistance-imparting agent is a monomer having a phenol skeleton with hydrogen or an alkyl group having 1 to 3 carbon atoms, bonded to at least one of ortho positions to the hydroxyl group of the phenol skeleton, and has a melting point of 145° C. or less and a molecular weight of 200 or more and 500 or less, and
- a content of the resistance-imparting agent is 0.4 parts by mass or more and 10 parts by mass or less with respect to 100 parts by mass of the resin component.
