Power Connectors

Manufactured from copper braid to standards EN1977 and EN13602 (supersedes BS4109), these tin plated copper braid earth leads have a wide variety of applications in many different industries.

 

Available in lengths and cross-sections to suit your individual needs, and with terminations sized to suit your application. Earth leads are typically used in the automotive, aerospace and rail industries, but are also essential for grounding in audio, video and computer systems.

Terminology

 

Real cross-sectional area: can be obtained by adding together all the cross sectional areas of each wire in the braid

 

Apparent cross-sectional area: is equal to the resultant area of the external dimensions of the braid, and is equal to about twice the real cross-sectional area.

 

Flexibility: depends essentially on the mechanical resistance of the material used, and on its diameter. Usually, electrical applications require annealed electrolytic copper, in either plain or tinned finish.

About Braid

Braids

Round Twisted Braid

The strands are wound in one direction  only; the flexibility of the braid is determined by the winding pitch. Production costs are lower and the product is equally flexible in every direction. Does not accept excessive torsion in the direction of the strand windings. Torsion in the opposite direction will cause a widening of the braid as the strands begin to separate. Strands may separate when bent or cut.

Flat ‘Tubular’ Braid

Can be made very thick with respect to its length, string sections can be made by using only one braid. Cross sectional area can be increased by  inserting one tubular braid inside another. Like the flat woven variety, tubular braid has poor lateral flexibility.

Round Braid

The strands are wound in opposite directions and the winding pitch determines the flexibility of the braid. Round braids are much more flexible that stranded cables of equal cross-sectional area. Unlike single wound braids, the strands of round braid to not separate when cut; the braid is flexible in all directions and resists torsion to the point that the strands will not separate and widen when twisted.
