As a specialized manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. brings you a high-performance grounding solution engineered for the demanding environments of modern CNC machine tools. Our Pure Copper Braided Tape is designed to provide a reliable, low-impedance path to earth, safeguarding sensitive electronic components from electrostatic discharge (ESD) and electrical noise. In an industry where precision and uptime are critical, ensuring a stable electrical ground is not an option—it's a necessity. This product represents our commitment to delivering components that enhance machine reliability and protect your valuable capital investment.
This grounding tape is constructed from high-purity, oxygen-free copper strands woven into a flexible braid. This specific construction offers several distinct advantages over solid conductors or flat straps for cabinet grounding applications.
- Superior Flexibility and Durability: The braided design allows the tape to withstand constant vibration, thermal cycling, and mechanical movement within the cabinet without work-hardening or fracturing, a common failure point for solid wires.
- Excellent Conductivity and Surface Area: Pure copper provides optimal electrical conductivity. The braided structure maximizes surface area, which is crucial for effective high-frequency noise dissipation and low-impedance grounding.
- Enhanced Current Carrying Capacity: The design facilitates better heat dissipation compared to a solid conductor of equivalent cross-section, allowing it to safely handle surge currents and fault conditions.
- Easy Installation and Routing: Its flexible, flat profile makes it easy to route around obstacles, through cable glands, and connect to grounding points that may not be in perfect alignment, simplifying cabinet assembly and maintenance.
Technical Specifications and Customization:

Benefits for Your CNC Operations:
Integrating this braided grounding tape into your machine tool electrical cabinets delivers tangible operational benefits:
- Improved Machine Accuracy: By providing a clean ground, it minimizes electrical "noise" that can interfere with servo drives, encoders, and control signals, leading to more precise machining.
- Increased Component Lifespan: Protects vulnerable PLCs, VFDs, and sensors from voltage spikes and ESD, reducing unexpected failures and downtime.
- Enhanced Safety Compliance: Establishes a proper equipment grounding conductor (EGC), which is a fundamental requirement for electrical safety standards, helping to protect personnel.
- Reduced Electromagnetic Interference (EMI): Effective grounding is key to containing EMI emissions from the cabinet, preventing interference with other nearby sensitive equipment.
- Maintenance and Serviceability: The durable and flexible design means connections remain secure over time, and the tape is easy to inspect, replace, or modify during service.

Frequently Asked Questions (FAQ)
-
Q: Why is a braided tape better than a solid copper strap for CNC cabinet grounding?
A: Braided tape offers superior flexibility to absorb vibration, better resistance to metal fatigue from bending, and a larger surface area for high-frequency noise dissipation, making it more reliable in dynamic machine environments. -
Q: Can you provide the tape with pre-attached terminals?
A: Yes. We can crimp and solder various terminal types—such as ring terminals, spade terminals, or plain lugs—onto the braid ends based on your cabinet's grounding stud or busbar specifications. -
Q: What is the difference between bare copper and tinned copper braid?
A: Bare copper offers the highest conductivity. Tinned copper (coated with a thin layer of tin) provides enhanced corrosion resistance in humid or mildly corrosive atmospheres and can be easier to solder. -
Q: How do I determine the correct cross-sectional area (mm²) needed for my application?
A: The required size depends on the fault current rating of your system and relevant electrical codes. We recommend consulting your machine's electrical drawings or a qualified engineer. We can advise based on common industry practices for CNC tools. -
Q: Is this product suitable for grounding moving parts within the machine, like the spindle?
A: Absolutely. Its flexibility makes it an excellent choice for creating grounding bonds to moving components, such as spindles or slides, to prevent static buildup and ensure electrical continuity. -
Q: Do you offer any protective sleeving for the braid?
A: Yes. We can supply the braid with optional PVC or silicone rubber sleeving. This protects against accidental contact with adjacent live parts, contains loose strands, and provides insulation in tight spaces. -
Q: What is your typical lead time for custom orders?
A: Lead times vary based on order quantity and customization (like terminations). Standard custom cuts are generally ready within 7-14 working days. We provide firm timelines upon order confirmation. -
Q: Can you provide test reports or certificates for the copper material?
A> Material test certificates (e.g., for copper purity) are available upon request. Our production follows strict quality control procedures aligned with our ISO9001 certification.
