Flexible Copper Braid Connectors

Flexible Copper Braid Connectors for Busbars & Power Systems

Avantar (Guangdong) Industrial Holdings Co., Ltd. Flexible Copper Braid Connectors are braided electrolytic-copper connectors for high current busbar and power equipment connections. Cross sections from 6 mm2 up to 600 mm2, Mounting holes from M6 to M16. The connectors are available in bare copper or tin-plated finish. Each connector takes in the vibration and thermal expansion while preserving reliable electrical transmission. The products comply with ISO 9001, CE and RoHS. Free samples are available on request.

What Are Flexible Copper Braid Connectors?

The goods are electrolytic braiding copper links for busbars, switchgear, transformers and other power equipment bridging. The woven strand construction absorbs mechanical vibration, thermal expansion and assembly misalignment and reduces stress on connected equipment without interrupting current flow, unlike rigid busbar linkages.

Key Product Features

Braided copper construction

Each connector is weaved from strands of electrolytic copper, which flex with movement without sacrificing conductivity or structural integrity.

Wide range of cross sections

From compact battery modules to huge transformer terminals, sizes from 6 mm2 to 600 mm2 allow you to adapt the connector to your ampacity requirement.

Absorbing vibration, thermal stress

Power plants, energy storage systems and industrial plants are subject to vibration and temperature cycling. The connections operate as a mechanical buffer between the stiff parts.

Finish: Tin-plated or bare copper

The tin plated version offers higher oxidation resistance in humid situations or enclosed cabinets. When tin plating is not required, bare copper is accessible.

Self production

The manufacturer does all the braiding, pressing, tin-plating, hole punching, and electrical testing in house which allows for direct engineering coordination on special orders.

Technical Specifications

Custom Design Options

Standard catalog items cover a wide range of busbar and switchgear applications, but site conditions vary. Avantar supports OEM and ODM customization for Flexible Copper Braid Connectors based on your drawings or project requirements.

Customizable parameters include:

• Braid width and thickness
• Overall finished length
• Terminal end shape and hole pattern (beyond M6–M16 standard range)
• Surface finish: bare copper or tin-plated
• Packaging format for high-volume orders

Share your current rating, installation space dimensions, and site environment details, and the engineering team can confirm the right specification before production begins.

Typical Applications

• Busbars — flexible jumper links between adjacent busbars in switchgear and distribution panels
• Transformers — compensating connections that absorb thermal movement between transformer terminals and busbars
• Battery energy storage systems (BESS) — inter-cell and inter-rack links in lithium battery cabinets
• Switchgear — vibration-isolated connections between rigid components
• Grounding systems — flexible grounding bonds where movement is expected
• Renewable energy projects — solar and wind power distribution connections

Quality and Certifications

Avantar’s products are manufactured in an ISO 9001 quality management system and meet CE and RoHS criteria. Documentation for export includes certificate of origin, material test results and RoHS compliance certificates for custom clearance and tender filing.

For big volume tender projects such as switchgear, transformer or energy storage, pre-shipment video inspection and third party witness inspection can be arranged. Fit-check and current-load verification is assisted by small trial batches before bulk procurement.

FAQ

Q: Why are products used instead of rigid busbar links?

A: Rigid busbar connections are inflexible, can break after some time or create dangerous mechanical stress on the linked equipment. The braided strand architecture of the connections absorbs vibration, thermal expansion and assembly misalignment while maintaining outstanding current carrying capability.

Q: What parameters should I confirm when I place an order?

A: Confirm conductor cross section (6-600 mm2), mounting hole size/pattern (M6-M16 or custom drawing), surface treatment (bare copper or tinned), overall completion length. If you are not sure, please provide your existing rating and installation constraints and the engineering team will be able to supply the suitable specification.

Q: Is Avantar a trade company or manufacturer?

A: Avantar is a factory direct company. The firm can do electrolytic copper braiding, end pressing, tin plating, hole punching and electrical performance testing by itself.

Q: What is the test papers and certifications?

A: Products with ROHS, CE and ISO 9001 requirements. Export shipments will be accompanied by a certificate of origin, material test reports, and RoHS compliance documents.

Q: How can I check the quality before I order a big quantity?

A: You can place a short trial order for fit-check and current-load check, review the copper material certificates and dimensional inspection records, or perform pre-shipment video inspection. We can provide unbiased third party witness inspections for big tenders.

Q: What is the MOQ, lead time and shipping options?

A: The MOQ is 100 pcs/model. Stock products are 7-15 working days lead time after order confirmation. We provide sea freight and air freight with quotation under EXW, FOB and other trade terms.
