TWT UTP cable, 25 pairs, Cat. 5, PVC, 305 meters per drum

Product Code: TWT-5UTP25

TWT UTP cable, 25 pairs, Cat. 5, PVC, 305 meters per drum

The cable consists of 25 pairs of solid copper conductors.
Conductor diameter is 24AWG.
Each conductor is enclosed in HDPE (high-density polyethylene) insulation.

Meets the requirements of Category 5.

Two conductors, twisted with a specially selected step, make up one twisted pair.
Twisted pairs are assembled around the central element, wrapped in a plastic film and enclosed in a common PVC jacket.

To facilitate cable termination, a rip cord is included under the jacket.

The cable is supplied on 305 meters drums. Other construction lengths can be supplied on request.
