Copper Braiding

Description of Copper Braiding

Copper Braiding also named copper earth strap,it is use in many different forms and components due to its strength, flexibility and superior ability to handle large currents at low voltages.The Copper Braiding made up of a tight weave of multi-strand, soft drawn copper.The flexibility of the braid is determined by the diameter of the copper wire. The smaller the wire the greater the flexibility and the larger the volume occupied by the braid and the more expensive the braid becomes.

Types of copper earth strap

Flat Copper Braid
Tuber Copper Braid
Copper Braid
Copper tinned Braid

Advantage of Grounding Straps

Highly Abrasion & UV Resistant
Can be Used as Grounding Straps
