Cable’s structure

1- Conductive core made of copper

2- Conductor insulation

3-Cable’s sheath

  • Conducting core is made of MM class copper wire;
  • Cores are insulated with polyethylene;
  • Two insulated cores are twisted into symmetrical pair, twisted pairs and single core are twisted then into a core;
  • Cable core may be produced of non-twisted pairs or single cores;
  • Cable jacket is made of flame retardant PVC Elastron;
  • Jacket color: white, gray, black.*

* If customized, jacket color may be of any color

Application

Twisted pair cables are design for permanent laying inside buildings and constructions, for usage in telecommunication networks and for devices connection in computer networks. Cables are used in frequency diapason up to 16 МHz (class 3), at working AC voltage not greater 145 V. cables with conducting core of 0,5 mm diameter are used in frequency diapason up to 100 МHz (class 5), at working AC voltage not greater 145 V.

Cables of unpaired twisting are design for permanent laying inside the building and constructions, for usage in fire- alarm and alarming devices, connection of control equipment and automatics.
