PURPOSE:To provide an insulator capable of well restraining the occurrence of a bow-tie water tree even in the existence of a defect therein, and ensuring freedom from a bloom. CONSTITUTION:0.1 to 30 weight parts of amidic ethylene containing 0.01 to 1.0wt% of nitrogen is mixed with 70 to 99.9 weight parts of polyethylene. Furthermore, 0.005 to 1.0 weight parts of silane having a total carbon number of 8 or more and an amino group, or siloxane having a total carbon number of 10 or more and an amino group, are added and subjected to a bridging process, thereby forming an electrical insulator for a wire and a cable. |
