Explore SpecificationsGrounding flexible straps, commonly constructed as woven copper braids, are critical electrical components engineered to establish a low-impedance path to earth or reference potentials. Unlike solid wires, copper braids are composed of hundreds to thousands of individual micro-fine copper wires (ranging from 0.05 mm to 0.20 mm in diameter) braided in configured patterns. This complex geometry provides crucial electrical and mechanical advantages.
Firstly, the flat, multi-strand structure of a braided strap utilizes the physical phenomenon of the skin effect. At high frequencies—such as lightning discharges, transient voltage surges, and Electromagnetic Interference (EMI)—electrical current tends to flow on the outer surface of a conductor rather than its center. The high surface-area-to-volume ratio of a flat copper braid drastically lowers its high-frequency impedance, ensuring rapid and safe discharge of high-frequency energy. Additionally, the mechanical construction absorbs continuous vibrations, accommodates thermal expansion cycles, and prevents fatigue fractures that typically compromise solid metal connectors in high-strain environments like EV battery assemblies, wind turbine cowls, and heavy industrial switchgears.

A detailed breakdown of materials, coating options, and termination technologies
Choosing the correct grounding flexible strap configuration depends heavily on your system's operating voltage, environment, and physical layout. Below is a comprehensive engineering guide outlining the primary configurations and material standards applied during our production processes:
We manufacture our braids exclusively using T1 and T2 grade electrolytic red copper, containing a minimum copper content of 99.90%. This purity level ensures electrical conductivity does not fall below 100% IACS (International Annealed Copper Standard) and limits internal electrical resistance to a minimum. High-purity copper also ensures excellent malleability, allowing our strands to withstand millions of flexural cycles without work hardening or micro-fracturing.
To prevent oxidation, chemical degradation, and galvanic corrosion at contact joints, we offer three primary plating finishes:
A critical failure point in grounding connections is the transition from the braided body to the contact terminal. Zhejiang Xingma utilizes three primary termination methods:
Providing custom electrical paths across demanding modern industries
Used to earth EV powertrains, battery casings, and onboard chargers. Our flexible designs withstand structural vibrations, chassis twists, and thermal expansion cycles.
Crucial for grounding solar panel racks, inverter cabinets, and wind turbine generator housings. Provides protection against lightning strikes and static build-up.
Woven straps serve as low-impedance pathways to earth high-frequency noise and protect server racks, network switches, and sensitive RF hardware from electrostatic damage.
Ideal for electrical bridges in industrial machinery, arc furnaces, and high-voltage power distribution switchgears. Safely handles high currents and continuous operations.
