Spring power cords, through their unique structure and material design, effectively reduce the risk of cable damage when frequently moved, stretched or twisted. The spring part provides extra length when the power cord is stretched, absorbs external forces, avoids direct tension on the internal conductor of the cable, and reduces the risk of breakage due to excessive stretching. When the external force disappears, the spring contracts to restore the power cord to its original shape, avoiding long-term tension and extending its service life.
The spiral shape of the spring can naturally guide the bending direction of the cable, prevent random twisting, and reduce the possibility of internal wires breaking due to repeated bending. The elasticity of the spring evenly distributes the tension throughout the cable, rather than concentrating it at a certain point, avoiding localized damage caused by excessive stress.
The spring power cord remains neatly coiled when it is contracted, reducing entanglement with other devices or cables, and reducing the risk of surface wear or internal short circuits caused by friction and extrusion. In mobile devices (such as robots and stage lights), the spring wire supports the cable in mid-air to avoid damage caused by ground friction or rolling.
Spring power cables are usually made of stainless steel or high-carbon steel, which has strong fatigue resistance and can withstand hundreds of thousands of expansion and contraction cycles without deformation. The cable sheath often uses TPU (thermoplastic polyurethane) or PVC mixed materials, which are resistant to pulling and oil pollution and adapt to industrial environments.
In frequently moving machinery (such as CNC machine tools and robotic arms), spring wires replace rigid cables to avoid hard bends or sudden pulls caused by mechanical movement. The outer layer of some spring wires has flame retardant, high temperature resistant or corrosion resistant properties, further reducing the risk of damage in extreme environments.
