PVC insulated PVC sheathed flame retardent, low smoke power cables up to 1kV. The cables meet the requirements of Specs. 16.К71-310-2001.

Structure

  1. Conductor – aluminium or copper, single or multi-wire, round or sector shaped, class 1, 2 as per national standard GOST 22483-77. The number of conductors: 5. 4-conductor cables may have 3 conductors of the same area and one conductor of smaller area (ground or neutral one).
  2. Insulation – low flammability PVC composition. Insulated multi-conductor cables carry identification coloring. Grounding conductor insulation is in two colors (green-yellow). Neutral conductor insulation is blue.
  3. Stranding – insulated conductors of 2-5-conductor cables are stranded to form a cable core. In the sector conductor cables PET film tape is laid over stranded conductors.
  4. Sheath – Over stranded insulated round-shaped conductors inner sheath of low flammability PVC composition is laid, which fills the interstices between the conductors. The minimal sheath thickness is 0,3 мм. Sector conductor cables are manufactured without inner sheath. Outer sheath is of low flammability PVC composition. For cables with round-shaped conductors and cross-section area up to 16 мм2 it is allowed to lay the outer sheath with simultaneous filling the interstices between conductors. In this case inner extruded sheath is not laid.

Аpplication

The cables are designed for power transmission and distribution in stationary equipment at alternating voltage 0,66 kV and 1kV, or at fixed voltage 1kV and 1,5 kV.

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-88/97 (ПНАЭ Г-01-011-97).

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

The cables are flame-retardent while bundled installation.
