Didn't you say that the electricity-proof wall is already a national standard? Why doesn't Smith water heater have an electricity-proof wall?

The electricity-proof wall is already a national standard. Smith water heater has no electricity-proof wall because Smith water heater adopts PS safety system, which is developed for common hidden dangers of ground wire, sensitively senses abnormal ground wire, instantly disconnects live wire, ground wire and neutral wire, and the safety of three-pole power failure is more guaranteed.

At present, water heaters with PS safety system (leakage protector) are widely used in parallel with anti-electricity wall technology. The safety level of this safety protection measure is equivalent to that of the electricity-proof wall, which meets the mandatory requirements of GB 4706.5438+0.

Smith water heater Jin GUI te Hu

A.O. Smith innovated and developed Jingui special care heating rod, which made a breakthrough in anti-corrosion and anti-pollution ability. Jingui special protection system composed of Jingui inner container and American strong anode rod improves the overall quality of water heater and ensures long-term and efficient operation.

1) patent Jingui special protection heating rod: long-term efficient heating, durable and energy-saving: Jingui coating is tightly protected, durable and antifouling. Low fouling ensures that the heating rod maintains high heat transfer efficiency and runs efficiently for a long time.

2) Patent Jingui special protective liner: the coating does not fall off: fiber is added to the special glaze, baked at 870℃, and it adheres tightly and does not fall off. The coating does not break: the coating expands and contracts synchronously with the steel plate of the liner without breaking, which is more effective in corrosion prevention and scale prevention.

3) High standard bearing capacity: under the strict "UL" standard, it passed 6,543,800 life tests. Cutting-edge technology eliminates virtual welding and ensures the pressure-bearing performance of the liner structure. Each batch of liners has passed the pressure test of 2 1 kg/cm2, which can ensure the safety even if the temperature changes.
