Estimating the term…
An object of the present invention is to provide an electrically insulative resin composition that exhibits superior electrical properties and processability and an electric wire or cable having a covering made of the resin. The electrically insulative resin composition comprises 60 to 90 percent by weight of ethylene-α-olefin copolymer (A) polymerized with a single-site catalyst and 40 to 10 percent by weight of another polyolefin resin (B), which is other than (A), wherein the composition contains a polyolefin having a graft-polymerized substituent with a dipole moment of not less than 4 Debye.
