Product Advantages:

1. Our flexible copper stranded wire is created by a high-speed wire stranding machine, utilizing a unique patented twisting process. The resulting wire is flexible, round, straight, and tightly structured, with no loose strands.

2. DONGJUE's flexible copper stranded wire undergoes advanced annealing, providing exceptional resistance to oxidation.

3. We offer customized production options for customers, allowing them to personalize wires with different layer directions, structures, specifications, and other non-standard products.

4. Our sintering and cutting processes ensure high dimensional precision, and our core surface treatment technology enhances the oxidation resistance of our products.

Good softness

When the twisted wire is bent, because each single wire is wound in a spiral around the twisted wire, when the twisted wire is bent, each single wire is stretched and compressed at the same time, the compressed part moves to the stretched part, only to overcome the friction when the single line moves, the friction is much less than the resistance generated by the single line bending in the parallel harness.

With the same specifications, the smaller the pitch, the shorter the single line moving distance when bending the strand, the smaller the friction force and the softer the strand; The strand with the same cross-sectional area, the more single strands, the softer the strand.


At ZHEJIANG DONGJUE CABLE CO., LTD., we take pride in our ability to provide custom welded assemblies and wire harnesses that cater to the unique needs of our customers. Our skilled technicians ensure precise and reliable connections, meeting the highest industry standards.
