What is the difference between 220v and 380v electric heating tube?

Three-phase electricity is 380V, and civil single-phase electricity is 220V. Simply put, in industrial electricity, one live wire and one zero wire can be selected for three-phase four-wire, and it can be used for civil use. When selecting the wire for 220V heating tube, it should be thick Some are fine, but the number of wires is less than 380.

Three-phase AC power supply: a power supply composed of three AC electric potentials with the same frequency, the same amplitude, and the phases differing by 120 degrees.

Three-phase AC has many advantages over single-phase AC. It has obvious advantages in power generation, transmission and distribution, and conversion of electrical energy into mechanical energy. Simple structure and excellent performance.

It should be noted that there is no specific distinction between the safety of electric heating tubes 220v and 380v, and it has little to do with voltage. Under the same power, 380V and 220V heating tubes have the same heating efficiency and the same safety.

Lay the electric heating plate on the ground (or in the incubator of the delivery bed). For the convenience of work, the power plug should be placed at one end of the corridor. After the plug is plugged in and the power is turned on, the red indicator light is on at this time, and the high and low switches are set to " Warm up for half an hour in the “high” gear (quick hot gear), touch the surface of the electric heating plate or observe the state of the piglets. It is advisable not to get together, and then turn the switch to the “low” gear (heat preservation gear), so there is no need to pursue high temperatures.
