UNILAY
or BUNCH: Conductors of any number are twisted together with the same
lay direction and cable lay length. Bunch construction will not have a well
defined geometric configuration and may have a varible cross-section. A
Unilay construction will have a well defined geometric configuration and
a defined cross-section. This type of cabling technique is usually used
on static designs.
CONCENTRIC
CONTRA-HELICAL:
Conductors that are surrounded by well defined layers of helically laid
conductors. Each layer has a reversed lay direction and an increasing lay
length in each succeeding layer. This type of cabling technique is usually
used on continuous flex designs.
CONCENTRIC
UNILAY:
Conductors that are surrounded by one or more layers of helically laid conductors
with the same direction or lay and increasing lay length in each succeeding
layer. This type of cabling technique is usually used on torsional flex
designs.
