What is the safety of the high tension line distance?

by:Taifeng Electronics     2020-05-15
British experts think the magnetic fields resulting from the high tension line TVC is 0. 4 micro tesla ( μt) , higher than the value, the children will face the risk. When the high tension line transmission, wire, will form the strong electric field around the air ionization and formation of corona discharge. This discharge can be heard and seen. The higher the voltage level, the stronger the corona wire, the greater the noise. Scientific studies have also shown that 220 kv high-voltage line around 40 meters - — Within 300 metres of people the chance of suffering from leukemia, cancer is in other parts of the number of times, the electromagnetic radiation can cause pregnant women abortion, fetal abnormalities and cardiovascular disease, great harm to people's. So what exactly is the safety of the high tension line distance? 220 kv high-tension line within the scope of the hundreds of meters of electromagnetic radiation is more than 0. 4 micro tesla; 132 kv high-tension line within the scope of the dozens of meters of electromagnetic radiation is more than 0. 4 micro tesla; 11 - 66 kv high-tension line in ten meters within the scope of the electromagnetic radiation is more than 0. 4 micro tesla; The high tension line buried in the ground only within several meters of electromagnetic radiation is more than 0. 4 the tesla. China's high tension line construction standards far cannot satisfy the security requirements. China's standards: magnetic induction intensity is less than 100 micro tesla would meet the high tension line construction standards. Foreign standards: magnetic induction intensity is lower than 0. 4 micro tesla would meet the high tension line construction standards, the gap is 250 times.
