    DIMENSION TABLE OF CABLE IN WELL
    The following table shows the max.Length from starter of motor to pump in well





  • If it used the star-delta connection to start the motor that the current will reduce(1×0.58),so the length of cable can increase(L×1.73)than the data in table.

  • If it used the star-delta connection to start the
    motor that the current will reduce(1×0.58),so the
    length of cable can increase(L×1.73)than the data
    in table.

  • For example in fact the current of submersible
    pump is lower than the load current 10%,the length
    of cable can be longer 10% than the data in table.
  • In order to reduce operating loss as far as
    possible,selected the cross section can much
    increase than the data in table.Especially for the
    condition which operating voltage is lower than rated
    voltage.
