Shenghui no electromagnetic radiation heating cable.

God fai double guide double heating cable to cable no electromagnetic radiation, using two (or more than two root stocks) copper and nickel alloy wire fever at the same time, each root (per share) copper and nickel alloy wire heating power is 9 w/m, total power cable fever is 18 w/m.

Current ACTS on the two (two) alloy conductor produce radiation reaction cancel each other out electromagnetic fields, the electromagnetic field in the radiation coupling state, in combined with the aluminum foil shield, because of the electromagnetic field has multiple direction, in horizontal and vertical test, god fai double guide double heating cable are within 0.7 fine long hair gauss. Distance measured ground 20 centimeters, the power density of 180 w / ㎡. 1 meter off the ground test, electromagnetic radiation is 0.2 fine long hair gauss. The international radiation protection association's working frequency limit of 0.1mt (millitesla) is equal to 100uT(micro-tesla) equal to 1mG (milligauss) as the standard of magnetic induction intensity.
