The specification of submersible pump cable is determined by the heating and voltage drop of the cable. In addition to the control of a certain current density to limit the temperature rise of the cable, the longer the cable length, the greater the voltage drop of the cable, the greater the impact on the start performance, operating performance and reliability of the motor. Therefore, for the submersible pump motor in the same well, when the submersible pump head is used differently and the length of the cable is different, the requirements for the cross-section of the cable are different.

When wiring, first determine the size of submersible pump cable according to cable length. For example, if the pump is equipped with 10 square meters of cable and 50 meters is required, the submersible pump cable configuration should be increased by 16 square meters.

If the submersible pump is used where the supply voltage is slightly lower than that required by the sewage pump and the required cable length is longer, the running cable of the pump will be larger for a long time. The motor of the sewage pump is very unfavorable. In this case, the sewage pump cable shall be equipped with YCW type or YC rubber sheathed soft cable. If not submerged in water, the YCW type is recommended.

The submersible sewage pump must be matched with the submersible pump cable according to the liquid medium to be transported. For example, liquids to be transported are corrosive. Therefore, the rubber parts on the outside of the cable must be made of stainless steel and corrosion-resistant submarine cable, otherwise the submarine cable will be corroded. A dangerous accident that leads to a spill.

Given a simpler algorithm: motor power ×2÷5 the amount obtained is matched to the submersible pump cable base then generally no problem. It's more economical. Do not heat the cable by hand when working normally. To be able to. But in order to be able to meet demand and the economy, it's better to choose an exact one.
