A twisted pair cable and a method of making the twisted pair cable are described. First and second insulated conductors are twisted about each other to form a twisted pair. A first insulating material surrounds a first conductor to form the first insulated conductor. In a first alternative or supplemental embodiment, the first insulating material directly abuts a circumference of the first conductor and has a first area with a first radial thickness and a second area with a thinner radial thickness. In a second alternative or supplemental embodiment, the first insulating material has a first area with a first radial thickness and a second area with a thinner radial thickness and the first area resides along a portion of the first insulated conductor which is abutting the second insulated conductor.
