Abstract
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.
Claims12
A binder unit for telecommunications cable having twenty-five pulp or paper insulated ring conductors forming a first conductor set and twenty-five pulp insulated tip conductors forming a second conductor set and in which:
- (a) each ring conductor forms a twisted pair with a tip conductor thus providing twenty-five pairs;
- (b) the conductor insulations have colors, a maximum of eight colors being present in the twenty-five pairs with the same colors used in both sets with each of the conductor sets having at least three colors, and with colors distinguishing certain of the conductors in each set from one another;
- (c) the insulation colors of the conductors in one of the sets all having a common style;
- and
- (d) with the conductor insulations of each pair visually distinguished from one another, each of the conductors of one common color and common style forms a pair with another conductor which is visually distinguished from conductors which form pairs with all other conductors of said one common insulation color and common style.
