  • YAKyXS are power cables with aluminum conductors, cross-linked (vulcanized) polyethylene insulation and PVC compound sheath.
  • They are used for the transmission and distribution of electrical energy in stationary installations for a rated alternating voltage of 660 and 1000 V with a frequency of 50 Hz.
  • They are designed for laying in cable structures, dry and damp industrial premises, in blocks, on specialized cable tray systems, channels, cable cellars, mines, collectors, tunnels, as well as for laying outdoors, provided there is no risk of mechanical damage during operation. They could be installed on bridges, highways without limiting on the level difference and in places of increased vibration.
  • The laying in the ground, trenches is not recommended. However, the laying is possible only using the protection against mechanical damage

Detailed description

Detailed description YAKyXS is a power cable with aluminum conductors, insulation made of vulcanized (cross-linked) polyethylene, and a sheath made of polyvinyl chloride plasticizer. It is designed for the transmission and distribution of electrical energy in stationary installations at alternating voltage of 0.66; 1 kV with a frequency of 50 Hz.

Scope of application This cable is used in cable structures, industrial and warehouse facilities, specialized cable bridges, ducts, cable mezzanines, shafts, and collectors. The cable is commonly used for wiring inside buildings, although it can also be installed outdoors if there is no risk of mechanical damage. YAKyXS is easy to install and has good tensile strength, making it suitable for use on bridges and multi-level routes. It is resistant to moisture and can be used in high humidity environments. It is not recommended for burial in the ground, and protection against mechanical damage is necessary in earth trenches.


YAKyXS has a construction that utilizes aluminum conductors. The conductors can be solid or stranded, with 1 or 2 flexibility classes (class 1, 2 DSTU EN 60228). The number of conductors varies from 1 to 5. They are insulated with cross-linked (vulcanized) polyethylene. In multi-conductor cables, the conductors are twisted into a core and have color coding. The external cable sheath is made of polyvinyl chloride plasticizer and fills the space between the insulated conductors.


The cable can be used in a stationary state within a temperature range of -50°C to +50°C. PVC material is thermoplastic and hardens at low temperatures, so installation is permissible at a temperature not lower than -15°C; otherwise, the cable should be preheated.

The maximum permissible air humidity at which the cable functions is 98% at a temperature of +35°C. The bending radius when laying the cables is 7.5 and 10 times the outer diameter of the cable for multi-conductor and single-conductor cables, respectively.

YAKyXS belongs to the category of power cables with insulation made of cross-linked polyethylene. The use of this material significantly increases the temperature at which the conductors can operate both during normal operation and during short-circuit conditions. The maximum allowable temperature rise of the conductors during operation should not exceed 90°C, during short-circuit conditions – 250°C, and in emergency mode – not more than 130°C, with a maximum working time of 8 hours.

The service life is not less than 30 years, and the warranty period of operation is 5 years.
