H02GINSTALLATION OF ELECTRIC CABLES OR LINES, OR OF COMBINED OPTICAL AND ELECTRIC CABLES OR LINESThis subclass covers installation of communication cables or lines, including those comprising a combination of optical and electrical conductors, or of lightning conductors as well as installation of power cables or lines. This subclass does not cover installation of purely optical cables, which is covered by groups G02B6/4401 , G02B6/46. In this subclass, the following expression is used with the meaning indicated: "electric cable" includes cables comprising optical conductors, e.g. fibres, in combination with electrical conductors. In this subclass it is desirable to add indexing codes of group H02G2200/00 whenever appropriate In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
