What is flexible copper stranded conductor?

Flexible copper stranded conductor is made of annealed copper strand wire, often referred to as dropper wire. The flexible copper stranded conductor is easy to bend, has high conductivity and large carrying capacity. It can be used as electrical connection wire instead of copper bus.

The cross-sectional area of the soft copper strand can reach 800mm² and the structure has 7 strands, 19 strands, 27 strands, 37 strands, 61 strands and so on.

The performance of flexible copper stranded conductor

Tinned flexible copper stranded conductor adopts electrolytic tinning process, ulti-strand simultaneous drawing is used in production. The drawing process adopts continuous annealing process, multi-strand stranded does not skip wire, no back strand.

The flexible copper stranded conductor has uniform appearance, beautiful luster, and has corrosion resistance, heat resistance and excellent weld ability and other industrial characteristics, tight conductor.

The wire harness outer diameter is not out of tolerance, high conductivity, etc.

The properties of tinned flexible copper stranded conductor can meet the requirements of DIN40500 (German industry standard) and ASTMB33 (American Society for Testing Materials).

The advantages of flexible copper stranded conductor

The flexible copper stranded conductor has excellent bending resistance, continuous strand, non-loose strand, simple and convenient for daily use or engineering construction. The performance of flexible copper conductor is better than that of aluminum stranded wire, and the conductivity is special tall and resilient

The application of flexible copper stranded conductor

The flexible copper stranded conductor is soft and flexible, it can be bent.The flexible copper stranded conductor can be used in electrical devices, switching appliances, batteries are used for connecting wires, etc.

Qualified flexible copper stranded conductor is round and straight. The structure is tight, not loose, convenient for various crimping and extrusion processing. Under normal circumstances, the softer the final flexible copper stranded conductor, the finer the mono filaments


The flexible copper stranded conductor is mainly used in electrical equipment for transmission and distribution, electrical equipment soft connection, electrified railway contact line, industrial furnace water cooled cable soft copper conductor, such as transformers, electric furnaces and electronic and electrical equipment, thyristor components soft connection wire. It can also be used as electrical industry grounding wire.


The flexible copper stranded conductor is a soft connection wire for electrical equipment and electronic appliances or components. The commonly used models for electrical connection wires in railway overhead contact system projects are TJR-95mm² and TJR-120mm².
