Abstract
A submersible component can include a conductor; and a polymeric material disposed about at least a portion of the conductor where the polymeric material includes at least approximately 50 percent by weight polyether ether ketone (PEEK) and at least 5 percent by weight perfluoroalkoxy alkanes (PFA). A submersible electrical unit can include an electrically conductive winding; and a polymeric composite material disposed about at least a portion of the electrically conductive winding where the polymeric composite material includes polymeric material at at least approximately 40 percent by volume and one or more fillers at at least approximately 10 percent by volume.
Claims20
A submersible electrical unit comprising:
- an electrically conductive winding;
- and
- a polymeric composite material disposed about at least a portion of the electrically conductive winding, wherein the polymeric composite material comprises polymeric material at at least approximately 40 percent by volume and fillers at at least approximately 10 percent by volume, wherein the polymeric material comprises one or more amphiphilic molecules, and the fillers comprise alumina and/or boron nitride.
A submersible electrical unit comprising:
- an electrically conductive winding;
- and
- a polymeric composite material disposed about at least a portion of the electrically conductive winding, the polymeric composite material comprising:
- one or more amphiphilic molecules;
- alumina filler in excess of about 30 percent by volume;
- and
- an amount of boron nitride filler in a range from about 0.1 percent by volume to about 10 percent by volume.
A submersible component comprising:
- a conductor;
- and
- a polymeric composite material disposed about at least a portion of the conductor, wherein the polymeric composite material comprises polymeric material at at least approximately 40 percent by volume and fillers at at least approximately 10 percent by volume, the fillers comprising a first filler having a relatively low surface area, and a second filler having a higher aspect ratio than the first filler, the first filler comprising a greater percentage by volume of the polymeric composite material than the second filler.
