The electricity-proof wall is equivalent to installing a resistor between the water heater and the user to reduce the voltage to an acceptable range for the human body. This technology was invented and patented by Haier in 2002. In 2007, 1.0' s lightning protection wall technology became an international safety standard.
Extended data
Haier's "anti-electricity wall" technology can not only solve the problem of forward leakage caused by internal components of water heaters, but also effectively solve the problem of reverse leakage caused by environmental leakage, thus achieving a leap from product safety to system safety.
Anti-electricity wall 3.0 technology, combined with fire protection design, is the highest level of protection for electric water heaters at present. Take Haier's new generation instant electric wall water heater PLUS9 equipped with electric wall 3.0 technology as an example. When installing, replace the socket directly and connect it to the water heater line in the form of socket crimping, so as to prevent the fire hazard caused by poor external wiring such as socket, and the household electricity consumption is safe and risk-free.
