DEFINITION

Classification: 333/243

Shielded type:

(under subclass 236) Subject matter wherein the long line comprises at least one electrical conductor surrounded by an electrically conducting screen.

(1) Note. This subclass includes, for example, coaxial cable-type conductors and other transmission lines having one or more conductors surrounded by an outer metal sheath which is designed for use as a conductor.

SEE OR SEARCH THIS CLASS, SUBCLASS:

12, for interference suppression and/or elimination systems which may include electrical screens or shields, and for conductor arrangements which involve shielding means or structure in addition to the conductor arrangement.
