TIEV-CC : INSIDE - OUTSIDE STATION WIRE

GENERAL

This specification covers the requirements of inside-outside station wire used for direct connection from the outside protector to the subscriber's set.

CONSTRUCTION :
Conductor : Solid annealed bare copper wire, 0.50,0.65 mm. (24,22 AWG) in size.
Insulation : Color coded solid high density polyethylene.
Twisted Pairs : The insulated conductors are twisted into pairs triple or quad. The four conductors of the quad shall be twisted into a " Spiral configuration with the red and green conductors diagonally four " opposite each other in the quad.

Identification of conductors :
