Cable for high-voltage electronic devices
A cable for high-voltage electronic devices including an inner semiconductive layer, a high-voltage insulator, an outer semiconductive layer, a shielding layer, and a sheath which are provided on an outer periphery of a cable core part in the order mentioned, wherein the high-voltage insulator is made of an insulating composition whose temperature dependence parameter DR found by the following expression is 1.0 or less: DR=log R23° C.−log R90° C. (where R23° C. is volume resistivity (Ω·cm) at 23° C. and R90° C. is volume resistivity (Ω·cm) at 90° C.). The cable for high-voltage electronic devices is small in diameter and has an excellent withstand voltage characteristic.
