Anti-electricity wall: (that is, water resistance attenuation isolation method) uses the resistance of water itself (for example, the national standard stipulates that the resistivity of tap water should be greater than1300Ω. Cm in 15℃), by selecting the material (insulation material), pipe diameter and distance of the water pipes in the electric water heater, an "electricity-proof wall" is formed. When the electric water heater is electrified, even if there is electricity, the water in the heating water tank will be attenuated by the resistance of the water itself when it passes through the "insulation wall", so as to achieve the purpose of isolating electricity, so that the water inlet and outlet ends of the water heater can reach almost zero voltage and extremely weak current below 0.02mA/kw.
Using the function of "anti-electricity wall" technology, not only can the electric water heater itself be blocked from electric leakage, but also the security threat caused by live ground wire or water pipe to the shower can be blocked. Therefore, the water heater adopts the technology of "insulation wall", which fully ensures the safety of people's bathing.
