1. Overview

Grounding braids and straps are conductive components designed to establish low-resistance electrical connections between equipment, systems, or structures and grounding points. They play a critical role in ensuring electrical safety, mitigating electromagnetic interference (EMI), and protecting against static discharge. These components are essential in modern electronics, industrial machinery, and infrastructure systems where reliable grounding is vital for operational integrity and personnel safety.

2. Main Types & Functional Classification

3. Structure & Composition

Typical grounding braids/straps consist of:

• Conductive Core: Annealed copper, aluminum, or tinned copper for optimal conductivity
• Braiding Structure: Woven strands (32-128 carriers) with 8-32 picks per inch for mechanical flexibility
• Protective Coating: PVC, nylon, or fluoropolymer jackets for environmental protection
• Termination: Ring terminals, spade connectors, or compression fittings with corrosion-resistant plating
