Some properties of a (DELTA)-string

The properties of 5D gravitational flux tubes are considered. With the cross section and fifth dimension in the Planck region, such tubes can be considered as stringlike objects, namely (DELTA)-strings. A model of attachment of (DELTA)-string to a spacetime is offered. It is shown that the attachment point is a model of an electric charge for an observer living in the spacetime. The magnetic charges are forbidden in this model.
