Product Description
1. Product Overview
Aluminium Braid, also named flexible aluminum braided strap / aluminum braided shielding sleeve, is woven from high-purity aluminum or Al-Mg alloy fine filaments via high-speed horizontal braiding machines, divided into flat braid (flexible grounding busbar) and tubular braid (EMI cable shielding sleeve). It replaces traditional copper braid for lightweight, low-cost conductive connection, grounding and electromagnetic shielding, widely adopted in new energy vehicles, power distribution, marine, aerospace and industrial automation systems.
2. Product Internal Structure
2.1 Raw Material Layer
- Bare aluminium braid: 99.7% pure aluminum / 5154 Al-Mg alloy wire, single filament diameter 0.12–0.30mm
- Tinned aluminium braid: ultra-thin tin plating (2–5μm) on aluminum filament surface, anti-oxidation & anti-galvanic corrosion
- Resin coated braid: outer PET/PP resin insulation coating, acid & abrasion resistant
2.2 Braiding Weaving Structure
- Flat Aluminium Braid
Multi-filament interlaced weaving (24/36/48 spindles), then cold rolling to uniform flat band; dense interlaced lattice disperses bending stress evenly, no concentrated metal fatigue.
- Tubular Aluminium Braid
Hollow cylindrical woven mesh, adjustable braiding coverage rate 85%–98%; higher coverage brings stronger EMI attenuation performance.
2.3 Optional Terminal Processing Structure
Two-end compression welded aluminum lugs (single-hole/double-hole), fully fitted crimp without broken strands; customizable hole diameter, lug width and overall length for bolt installation.
3. Application Fields
3.1 New Energy Vehicle (EV/HEV)
Flat terminated aluminium braid as flexible ground strap between lithium battery pack, motor controller, vehicle chassis; lightweight design reduces vehicle weight, withstands road vibration long-term.
3.2 Power Distribution & Electrical Equipment
Flexible connecting busbar for switchgear, transformer, low-voltage cabinet; absorbs thermal expansion displacement of rigid copper bars, avoids assembly stress cracking.
3.3 Cable EMI/RFI Shielding
Tubular aluminium braid wrapped outside signal cables, new energy wiring harness, coaxial lines; isolates electromagnetic interference to guarantee stable signal transmission for industrial control, monitoring equipment.
3.4 Marine & Offshore Engineering
Tinned aluminium braid for ship grounding, offshore platform lightning protection; salt-spray corrosion resistance adapts marine humid saline environment, lower cost than copper braid for large-scale marine wiring projects.
3.5 Aerospace & Rail Transit
Lightweight bonding and lightning protection braid for aircraft, high-speed train cabinet connection; meets strict weight reduction requirements while ensuring continuous conductive loop.
3.6 Industrial Furnace & Heating Equipment
High-temperature aluminium braid connecting silicon carbide heating elements, fast heat dissipation, stable large-current conduction for industrial electric furnaces.
3.7 Photovoltaic & Energy Storage Station
Grounding flexible strap for PV brackets, energy storage cabinet internal connection; reduces overall project material cost, convenient on-site bending installation.
