Bare stainless steel cable is made of stainless steel to resist rust and corrosion, while the cable with plastic sheath inside is made of iron, it is not resistant to rust and corrosion. Using a plastic coating for a while can become brittle. broken and the iron core inside can be rusted leading to unsafe cable breakage when hanging the pump.

It is recommended to use a magnetic start box for the pump because when the power source is out of phase or the voltage is unstable, the magnetic starter box helps to control, close the pump to help protect the motor from unwanted short-circuiting.
