Braided Shield is a flexible metallic mesh component used in heating cables for electromagnetic interference (EMI) protection and mechanical reinforcement.
A Braided Shield is a conductive layer typically constructed from interwoven strands of tinned copper, aluminum, or stainless steel wires. In heating cable applications, it encases the inner conductive elements and insulation layers. Its primary functions are to provide a low-resistance path for fault currents, shield against external electromagnetic interference (EMI) and radio frequency interference (RFI), and offer mechanical protection against abrasion, crushing, and cut-through. The braided design maintains flexibility while ensuring consistent coverage and grounding capability.

It provides electromagnetic interference (EMI) protection, mechanical strength, and a reliable grounding path for safety and performance.
Tinned copper is most common due to its conductivity and corrosion resistance; aluminum and stainless steel are used for specific applications.
Higher coverage (e.g., 90-95%) improves shielding but reduces flexibility; 80-90% balances effectiveness with cable bendability.
