also be used as another option which option is used will depend on cost as determined by the available rig equipment on the surface the tool 40 has a lower end housing 46 with a downhole oriented opening 48 designed to accept the male connector 50 that has spaced circumferential contacts 52 and 54 that are separated axially by a ring of an insulator 56 the tool 40 internal to the housing 46 features axially oriented brushes 58 on rotating shafts 60 the brush segments 58 can be spaced so that when the tool 40 is fully landed the segments of the brush 58 will align with the contacts such as 52 and 54 to polish them and to remove buildup that can or has interrupted contact with the esp 62 shown in fig7 alternatively the brush material 58 can have an axial length to span all the contacts and the insulators between them when the tool 40 is fully landed as shown in fig5 the shafts can be symmetrically distributed in the tool 40 and preferably even in number so that half turn one way and half the other way so that the tool 40 is not subjected to a net torque and will not tend to rotate about its longitudinal axis when all the brushes are turning this alternative could be more useful if the tool 40 is run on rigid tubing alternatively the tool body 64 can be rotatably mounted to the support 42 and driven to rotate on its own axis such as with onboard power supply 44 or a remote power feed that comes.
