Cable design
- Copper conductor
- PVC compound insulation
- PVC extruded cushion filling the interstices between the insulated conductors to make a round shaped cable
- Armor of steel galvanized tapes
- PVC compound sheath
Conductor coding
- Color coding using a counting pair in each layer is applied. The counting pair conductors must be of different colors and must differ from the colors of other conductors. Each separate layer must have one conductor of red colour and one of blue. These two are placed side by side and called a counting pair. Other conductors must be white. The blue conductor is used to find the required one by counting from it. The red conductor is used to determine the direction of counting.
- The digital code is applied by printing. The colour of the digits must contrast with the main colour of the conductors insulation. The bottom of the digit must be underlined. The counting starts from 1, each conductor has a unique number.
Application
- This cable type is used for transmission and distribution of power in electric installations with rated alternating voltage of 660 V or 1000 V and 50 Hz frequency. .
- Its laying has no restrictions of the difference in elevation along the cable route including its vertical sections.
- The cable is intended to operate in electric networks of alternating voltage with grounded or isolated neutral. Their time of operating in single-phase earth fault mode should not exceed 8 hours and the total operating time in single-phase earth fault mode does not exceed 125 hours per year.
- These cables are designed for laying of single cable lines in the cable installations and industrial premises. Bunched laying is allowed only in the outdoor electrical installations and industrial premises with just occasional presence of the maintenance staff. In that case a passive fire protection is required.
