Color coding identification of conductors in telecommunications cable

摘要

A binder unit of twenty-five twisted pairs of pulp or paper insulated conductors formed of ring sets and tip sets with a maximum of eight colors for the insulations. The same colors are used in both sets with each conductor set having at least three colors to distinguish certain conductors in each set from one another. Insulation colors of the conductors in one of the sets all have a common style. While conductor insulations of each pair are distinguished visually from one another, each conductor of a certain color and style forms a pair with a conductor, which is visually distinguished from further conductors which are paired with all other conductors of that certain color and style.
