High-pressure electromagnetic radiation that transmission line of electricity produce is it influence to store to communication line , broadcast and television , human ecology in, paid close attention to more and more by people. Indicate according to research and relevant test , voltage transformer , supervoltage distribution device and supervoltage electric wire are in running , will form the electromagnetic radiation frequently of engineering of certain intensity. For this reason, this text combines the high-pressure transmission line of electricity electromagnetic radiation safety standard that our country makes, probe into the impact on surrounding environment , health of electromagnetic radiation of the high-pressure transmission line of electricity and interference to the radio, Through small stream village high-pressure transmission line of electricity electrom
