DEFINITION

Classification: 174/68.1

CONDUITS, CABLES OR CONDUCTORS:

(under the class definition) Structures of conduits, cables or conductors.

(1) Note. See this class, main class definitions, especially 2, 3, 6, 8, and 9 as well as main class notes (1) through (14) for criteria which distinguish the structures found in this class from those of other classes.

SEE OR SEARCH THIS CLASS, SUBCLASS:

8+, particularly subclasses 24+ for such structures utilizing fluids.

32+, for anti-inductive structures.

37+, for underground installations.

40+, for overhead installations. 48, and 49, for wall mounted installations.

SEE OR SEARCH CLASS

254, Implements or Apparatus for Applying Pushing or Pulling Force,

134.3+, for methods or apparatus used in installing such structures.

294, Handling: Hand and Hoist-Line Implements, especially

19, for devices used in placing such structures.

333, Wave Transmission Lines and Networks,

236+, for long transmission lines having distributed electrical parameters, and subclasses 1+ for plural channel systems of such lines.

338, Electrical Resistors, appropriate subclasses for electrical resistors, per se. See the class definition under Class 338 for certain classification lines relating to this subject matter.

343, Communications: Radio Wave Antennas,

700, for antennas which may include a conduit, cable or conductor. See also (4) Note. B, under subclass 700 and (1) Note under subclass 900 of this class (343) for classification lines between conduits, cables or conductors and antennas.

405, Hydraulic and Earth Engineering, 154+, for methods and apparatus for installing or laying conductors, drawing them through conduits, or placing them on poles.
