As a leading manufacturer of electrical safety components, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable, high-performance grounding solutions for industrial and commercial applications. Our Pure Copper Braided Tape is engineered to ensure optimal electrical continuity and safety for electrical enclosure doors, effectively mitigating the risks associated with electrostatic discharge and fault currents. With over a decade of experience and a commitment to stringent quality control under our ISO 9001 management system, we deliver products that meet the exacting demands of global markets, from North America to Southeast Asia. This tape is a critical component for maintaining system integrity and protecting sensitive equipment.
This 25mm wide, 1-meter long braided tape is constructed from high-purity copper, offering superior electrical conductivity and durability. Its primary role is to establish a low-impedance path to ground for electrical cabinet and enclosure doors, which are often isolated from the main chassis. This connection is vital for:
- Safeguarding Personnel: Preventing electric shock hazards by ensuring any stray voltage on the door is safely directed to ground.
- Protecting Equipment: Shielding internal components from electromagnetic interference (EMI) and dissipating static charges that can damage sensitive electronics.
- Ensuring Compliance: Helping electrical installations meet safety standards that require bonded and grounded enclosures.
- Enhancing Reliability: Maintaining consistent electrical performance in environments with vibration or frequent door operation, thanks to the tape's flexible braid design.
The braided construction is a key feature, providing exceptional flexibility and fatigue resistance compared to solid straps. This allows for easy installation around hinges and corners without cracking or breaking, ensuring a permanent and reliable ground connection even with repeated door movement. The high surface area of the braid also ensures excellent current-carrying capacity.

Key Product Features and Client Benefits:
- Optimized Electrical Performance: The use of pure copper minimizes resistance, providing a highly efficient path for fault currents and static dissipation. This translates to more reliable grounding for your electrical systems.
- Superior Mechanical Durability: The woven braid withstands constant flexing, twisting, and vibration without failure. This means a longer service life and reduced maintenance costs for doors that are opened frequently.
- Corrosion Resistance (Tinned Option): For applications in humid or corrosive environments, we offer tinned copper braid. The tin plating significantly slows oxidation, maintaining conductivity and a clean appearance over time.
- Ease of Installation: The flexibility of the braid allows it to be routed easily in tight spaces. It can be cut to length on-site and terminated with standard crimping tools, saving installation time and labor.
- Wide Application Scope: Beyond electrical box doors, this tape is suitable for bonding panels in switchgear, grounding in telecommunications racks, and providing equipotential bonding in various industrial machinery.

Frequently Asked Questions (FAQ)
-
Q: What is the main purpose of this braided tape?
A: Its primary purpose is to electrically bond and ground movable doors on electrical enclosures, control panels, and cabinets. This prevents static buildup, reduces EMI/RFI, and ensures safety by providing a path for fault current. -
Q: Why choose braided tape over a solid copper strap for door grounding?
A: Braided tape offers far greater flexibility and resistance to metal fatigue. A solid strap can crack or break after repeated bending from door movement, while a braid will flex continuously without losing conductivity. -
Q: Is the 1m length fixed, or can I order different lengths?
A: The 1m length is a standard offering for convenience. We routinely supply custom lengths, either pre-cut or in continuous rolls, to suit specific project requirements. Please inquire for bulk or non-standard orders. -
Q: What is the difference between bare copper and tinned copper braid?
A: Bare copper has a bright metallic finish and offers excellent conductivity. Tinned copper has a silver-colored tin coating that provides enhanced protection against oxidation and corrosion, making it preferable for damp, salty, or industrial atmospheres. -
Q: How do I terminate the ends of the tape for installation?
A: The ends can be terminated using standard copper lugs or ring terminals, which are crimped or soldered onto the braid. We can also supply the tape with terminals pre-installed to your specifications, saving you assembly time. -
Q: What is the current-carrying capacity of the 25mm wide tape?
A: The ampacity depends on the specific braid density and construction. As a general guideline, a high-quality 25mm pure copper braid can safely carry significant short-circuit current for grounding purposes. For precise technical data, please contact us with your application details. -
Q: Do you provide any documentation or certification with the product?
A: Our manufacturing is governed by an ISO 9001 quality management system. Certificates of Compliance or test reports can be provided upon request to verify material purity and conformance to specifications. -
Q: What are the packaging and lead time for this product?
A: Standard items are typically packaged in plastic bags or boxes. Lead times vary based on order quantity and customization. We maintain efficient production and logistics to ensure timely delivery through our established port network.
