Constructions
The following are standard constructions available:

Strand
1x3: A simple construction of three single wires twisted together. This construction makes it a very flexible strand in small diameters. The strand becomes less flexible as diameters increase.

1x7: Six wires are laid around one center wire. This strand is more flexible than a 1x3. This construction is commonly used for push-pull applications and for conductive needs with low flexibility.

1x19: Twelve wires are laid around a 1x7 center. This construction is used for more flexible needs than a 1x7 in push-pull and conductive applications. A 1x19 strand is almost as high a breaking strength as a 1x7 strand with the same diameter.


Cable
3x7: A combination of three 1x7 strands twisted together. This is a very flexible cable in small diameters.

7x3: Six 1x3 strands cabled around a 1x3 center strand. The properties of this cable are the same as a 3x7 cable but is a much smoother cable on the outside. This cable is used for application requiring a smooth jacket but it is more costly than a 3x7 cable.

7x7: Six 1x7 outside strands are cabled around a 1x7 strand center. This is the most standard cable construction. This produces a very flexible cable with good cycle life and excellent breaking strength.

7x19: Six 1x19 strands are cabled around a 1x19 center strand. This is the most flexible standard construction for cable. This cable gives you a high cycle life but has a lower breaking strength and is more costly than a 7x7 cable.

A wide variety of special constructions have been produced and are available for manufacture based upon customer requirements. See Custom Products for more information.
