Abstract

The present invention relates to cables including one conductor and/or an insulating layer surrounding the conductor. The insulating layer comprises a mixture of a polypropylene resin and an ethylene-propylene copolymer resin. 60 to 70 weight% of the mixture based on the total weight thereof is eluted in an elution test using a boiling xylene solution.
