Power cables for overhead lines
Uo/U - 0.6/1 kV VDE 0276-626/4F // FN KI 02.003
In constructions for distribution networks these cable permit suspension on fasades and trees.
The power cables with XLPE insulation for overhead lines - self-supporting type are designed for transfer, distribution and supply with electrical power in networks low voltage Uo/U 0.6/1 kV.
In constructions for distribution networks these cable permit suspension on fasades and trees.
They allow crossing of forest areas without cutting and maintenance of openings in the wood.
The suspension and support of the whole bundle is carried out by the phase ( basic ) insulated current-conductive

The power cables with XLPE insulation for overhead lines - self-supporting type are designed for transfer, distribution and supply with electrical power in networks low voltage Uo/U 0.6/1 kV.
In constructions for distribution networks these cable permit suspension on fasades and trees.
They allow crossing of forest areas without cutting and maintenance of openings in the wood.
The suspension and support of the whole bundle is carried out by a supporting insulated neutral wire of aluminium steel conductor or of aluminium alloy.

Uo/U - 0.6/1 kV NF C 33-209
The power cables with cross-linked polyethylene (XLPE) insulation for overhead lines are designed for electrical installations with alternating power networks with nominal voltage Uo/U 0.6/1 kV or in direct power networks with maximum voltage according to land 0.9 kV.
The cables with supporting (bearing) zero conductors are used for building networks in city and urban areas and the self-supporting type cables are for building distribution networks in these areas.
Cables for overhead installations may be used in different types of installations: on free hanging facades; between posts; on fixed facades; trees and poles. Interception of forest areas without the need of clearance and maintenance of openings is allowed.
-Cables with supporting zero conductor, the whole bundle is suspended and carried by the supporting conductor, which is made of aluminum compound.
- Self-supporting construction, suspension and carrying of the whole bundle is done by the phase insulated conductors. Bundles can include one or two additional conductors for public lighting and control pair

Uo/U - 2/20 kV FN KI 02.004/06 / / SFS 5791/94
Conductors with XLPE insulation for overhead lines, are designed for transfer and distribution of electrical power in overhead electrical networks with nominal voltage to Uo/U/Um 12/20/24 kV and frequency 50 Hz.
The main characteristics of overhead lines with XLPE insulation overhead conductors are low susceptibility to operational failures when conductors strike against each other or when a tree is temporarily leaning on the line. Also the space in the terrain required for the line is narrower, specially in casse of parallel lines
