SECTION H – ELECTRICITY


H 02GENERATION, CONVERSION, OR DISTRIBUTION OF ELECTRIC POWER


H 02 GINSTALLATION OF ELECTRIC CABLES OR LINES, OR OF COMBINED OPTICAL AND ELECTRIC CABLES OR LINES (insulated conductors or cables with arrangements for facilitating mounting or securing H01B 7/40; distribution points incorporating switches H02B; guiding telephone cords H04M 1/15; cable ducts or mountings for telephone or telegraph exchange installations H04Q 1/06)


Notes

(1)This 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.

(2)This subclass does not cover installation of purely optical cables, which is covered by group G02B 6/46.  [6]

(3)In this subclass, the following expression is used with the meaning indicated:  [6]

 "electric cable" includes cables comprising optical conductors, e.g. fibres, in combination with electrical conductors.  [6]
