As a professional spring coiled spiral cable assemblies manufacturer, Most of our Spring coiled Medical Cables, Spiral ethernet cables and RJ45 RJ50 Scanner cables produced by us using PU spring design cable, which is a device power connection wire that works using elasticity. It is usually made of TPU material cable and is used to control power connection for mobile devices. It can quickly rebound and restore shape in a short period of time. It is widely used in mobile power connection devices such as  automobiles, machinery, telephones, and instruments. and also use for medical products such as Spring coiled ECG EEG EKG EMG Snap leadwire cable, PU material is the best material for making spring wires, with characteristics such as flame retardancy, oil resistance, acid and alkali resistance, low temperature resistance, UV resistance, wear resistance, water resistance, and aging resistance. It is becoming more and more widely used as the preferred material for spring coiled wires.

Its main applications include:

1. PU/PVC sheathed (shielded) spring wire for control systems: used in medical treatment, communication, automobiles, robots, etc.;
2. PU/PVC sheathed (shielded) spring wire for power systems: used in processing equipment, cranes, production lines, etc.;
3. PU/PVC sheathed (shielded) spring wire for data/bus transmission: used in CNC machine tools, production lines, logistics systems, robots, etc.
4.  

The names and size relationships of each part of the spring wire are:

1. Spring wire diameter d: the diameter of the cable used to make the spring wire;
2. Spring wire outer diameter D: the maximum outer diameter of the spring wire;
3. Spring wire inner diameter D1: the minimum outer diameter of the spring wire;
4. Spring wire length L: the static length of the spring wire under no external force;
5. Spring wire working length L0: the dynamic length of the spring wire under external force;
6. Spring wire extended length A: the total length of the straight line required to wind the spring wire.
