CONDUCTORS

BUNCHED CONDUCTORS

Bunched Conductors consists of one or several multiwires. The multiwires are bunched to form a conductor. The individual wires have no defined position in the conductor.

Bunch stranded conductors are used for a wide range of cable applications with focus on low cost production.

CONCENTRIC STRANDED CONDUCTORS

Conductors with regular lay construction. Each individual wire has a defined position in the conductor. One or several lays of wires are concentrically placed over one central wire.

1+6	1+6+12	1+6+12+18	1+6	1+6+12	1+6+12+18

CONCENTRIC STRANDED CONDUCTORS ARE PARTED IN TWO TYPES

UNILAY	TRUE CONCENTRIC
Unilay Concentric	Equilay Concentric
same lay direction of the layers same lay length of the layers round construction smooth surface	alternating lay directions of the layers same lay length of the layers very round construction smooth surface
Unidirectional Concentric	Conventional Concentric
same lay direction of the layers different lay length of the layers very round construction smooth surface	alternating lay directions of the layers different lay length of the layers very round construction smooth surface

SEMI-CONCENTRIC CONDUCTORS

Semi-concentric Conductors are not depending to the regular constructions of the Concentric Stranded Conductors but provides the same positive characteristics like roundness and smooth surface.

Concentric Stranded Conductors and Semi-concentric Conductors are suiting very well for cables with high value insulation materials due to roundness and smooth surface.

Another advantage of these constructions is a small diameter due to the compact construction by defined layings. In combination with thin insulation thickness cables can be designed with small over all diameter.
