1. In terms of manufacturing technology,
When it comes to lines, the main dissimilarity between soft and hard lines is that hard lines are usually thick and consist of single strands, whereas soft lines are made up of multiple strands forming a cohesive unit.
A flexible wire refers to a wire that consists of several strands of conductive solid metal wires that have a diameter of below 1mm.
A hard wire is a type of conductor that is made up of a single solid metal with a diameter exceeding 1 mm.
Single-strand wires are typically used for hard wires that are less than 10 square meters in size, while household lines are typically no larger than 6 square meters. It is clear from the complexities involved in manufacturing these wires that their square meter cost exceeds that of hard lines.
2. In terms of mechanical properties,
The wire that is flexible possesses high resistance to fatigue and is weak in terms of tensile strength in the longitudinal direction. Additionally, it shows strong resistance in cases of transverse fracture.
The longitudinal tensile resistance of hard wire is very strong, but it lacks transverse fracture resistance, resulting in weak fatigue resistance.
The suitability of these two wires depends on their mechanical properties, which are markedly different from each other.
Flexible copper wire has a low resistance to tensile force, especially in terms of longitudinal tensile resistance. This characteristic makes it unsuitable for use in scenarios where it needs to be buried underground such as walls, floors, and pipes. The reason being is that when pulling the pipe, some copper wires can be dislodged during the process, posing a potential safety hazard for future use. Therefore, it is recommended that alternative materials with higher tensile strength be used in such situations.
If you're in need of a wire that can handle flexible connections, then soft copper wire is the perfect option for you. This wire offers great fatigue resistance, meaning it can withstand transverse fracture and is suitable for a variety of operations. Whether you're dealing with elevator cables, overhead crane cables, electric vehicle charging lines, or mobile phone charging cables, this wire can handle it all. Since these applications require a flexible wire that can be bent frequently to produce curvature changes, the fatigue resistance of soft copper wire makes it an ideal choice. While steel wire also has high fatigue resistance, soft copper wire is the preferred option for these scenarios.
Bare copper wire is best suited for permanent locations such as buried walls, pipes, and grounds, where it is commonly used as a mainline due to its durability and reliability. However, it may not be suitable for environments where frequent bending is required. It is essential to understand the specific operating scenarios to ensure the correct type of wire is used. In summary, bare copper wire is ideal for stationary settings but may not be practical for areas with regular movement or bending requirements.
