Brand design

1. Conductive conductors - single - wire of soft copper wire with a nominal diameter of 0.51 mm.

2. Insulation - made of polypropylene, applied as a continuous layer.
3. Twisted pair - consists of two insulated conductors, differing in color, twisted in pairs with coordinated pitches.
4. Core - twisted pairs are twisted into elementary 2, 3 or 4 - paired bundles.
5. Belt insulation - made of polymer tape with an overlap of at least 25% .
6. Screen - applied longitudinally from an alumopolymer tape. Tinned copper contact wire is laid under the screen.
7. Sheath - made of polyethylene.
