PVC insulated and sheathed, flame retardent, low smoke control cables. The cables meet the requirements of Specs. 16.К71-310-2001.

Structure

  1. Conductor — copper, single, class 1 as per national standard GOST 22483-77.The number of conductors: 4-61.
  2. Insulation — PVC composition of low flammability.
  3. Stranding — insulated conductors are stranded to form a core. Each layer has a marker pair, its insulated conductors carry identification coloring and differ from the other conductors. Conductors that carry color or numeral marking have letter Ц in their ID.
  4. Sheath — PVC composition of low flammability.

Аpplication

The cables are designed for fixed connection to electric devices, machines and assemblies of electric distribution devices for alternating voltage up to 660 V and frequency up to 100Hz.or for fixed voltage up to 1kV.

The cables are produced for industrial application and application in nuclear power stations by deliveries to home and export markets.

The cabels are designed for use in cable structures and areas, including nuclear power systems, class 3 or 4 as per classification ОПБ-88 (ПНАЭ Г-01-011-97).

The cables are flame-retardent while bundled installation.

Class of fire safety on classification НБП 248 - П1.7.2.1.
