"Buying multi-core spring wires is not buying a rope, but buying an equipment fuse." This is the evaluation of the multi-core spring wire by the person in charge of a medical equipment manufacturer.
In the field of industrial procurement, how to avoid being "pitted to bankruptcy" by inferior wires? Customer word-of-mouth reveals four core criteria.
Bending life is the primary indicator. A supplier once used "static test" data to impersonate it, resulting in the core breaking after 1 month of customer installation. Truly high-quality wires must be tested
by a third party: the continuous bending machine can still be powered on normally after 100,000 times. The multi-core spring wire purchased by a robot manufacturer only had one broken core after the
vise was repeatedly bent 100 times, which was far better than the industry average.
The material of the wire core directly affects the signal stability. A medical equipment manufacturer was greedy for cheap use of tinned copper wires, resulting in electrocardiogram signal interference,
and finally recalled the product with a loss of 3 million yuan. The multi-core spring wire using silver-plated copper wire has a resistance of less than 0.01Ω/m, which can ensure zero distortion of
high-frequency signal transmission.
The number of shielding layers is key to measuring anti-interference capabilities. Industrial scenarios require at least 3 layers of shielding (aluminum foil, woven mesh, ground layer).
A robot manufacturer once purchased a single-layer shielded wire, and the robotic arm lost control due to electromagnetic interference, and the production line was paralyzed for 8 hours.
By switching to multi-core spring wires, the equipment can still operate accurately even in strong electromagnetic environments.
The ability to customize determines the suitability of the cable. Outdoor equipment requires IP67 waterproof connectors, and a charging pile company did not customize waterproof connectors,
resulting in a short circuit caused by rainwater infiltration, and 20 equipment burned out and lost 800,000 yuan. High-quality suppliers can provide full-dimensional customization services from cable length,
joint type to number of shielding layers.
In the era of Industry 4.0, multi-core spring wires have been upgraded from "consumables" to "equipment lifelines". It not only reduces maintenance costs but also ensures that equipment maintains stable
performance during high-load operation. As the person in charge of procurement of an automobile manufacturer said: "Choosing multi-core spring wires is choosing the efficiency and safety of equipment.
