Introduction
Cables are essential components in many industries, ranging from telecommunications to construction. One critical aspect of a cable is its strand construction, which refers to the arrangement of wires or filaments that make up the cable. Strand construction plays a vital role in determining the cable’s strength, flexibility, and resistance to abrasion and fatigue. As such, selecting the right type of strand construction for a particular application is crucial to ensure the cable’s durability and reliability.
Here in this blog, we’ve discussed the different types of strand construction commonly used in cables, along with their unique characteristics and applications.
Types of Strand Construction
-
Concentric Strand:
Concentric strand is a type of cable strand construction that consists of a central wire or core surrounded by one or more layers wound in the opposite direction to the layer below it, resulting in a cable with a uniform circular shape. Additionally, concentric strand cables are less likely to suffer from corrosion due to their smooth and uniform surface, making them ideal for harsh environments where exposure to moisture and chemicals is common. The ability of concentric strand cables to maintain their shape and electrical properties over time makes them a popular choice for many industries, including construction, transportation, and telecommunication.

Compressed strand:
A compressed strand is a type of cable strand construction that involves compressing multiple wires or filaments together to form a single solid strand. The compressed wires are then twisted together in a helical pattern to create a cable that is strong and durable. Compressed strand construction is often used in high-stress applications that require exceptional strength and resistance to abrasion and fatigue. Compressed strand cables are also commonly used in applications that require high flexibility, such as mining and drilling operations, as the compressed wires can withstand repeated bending without breaking or losing their shape. Overall, compressed strand cables are a reliable and durable option for demanding applications that require exceptional strength and flexibility.

Rope lay Strand:
Rope lay strand is a type of cable strand construction that consists of a central wire or core surrounded by multiple layers of wires or filaments twisted together in a helical pattern. The wires in each layer are twisted in the opposite direction to the layer below it, similar to the construction of a rope. Additionally, rope lay strand cables are resistant to abrasion and fatigue, making them ideal for use in harsh environments where exposure to moisture and chemicals is common. Overall, rope lay strand cables are a durable and reliable option for demanding applications that require exceptional strength and flexibility.
-
Bunch Stranded:
Bunch Stranded is a type of cable strand construction that consists of multiple wires or filaments of the same size and material twisted together in a helical pattern to form a cable. Unlike other strand constructions that use a central core, bunch-stranded cables do not have a distinct core wire. Instead, the wires are twisted together in a random pattern, giving the cable a flexible and pliable feel. The random arrangement of the wires in a bunch of stranded cables allows for easy bending and twisting without causing damage to the cable allows for easy bending and twisting without causing damage to the cable or compromising its electrical properties Overall, bunch-stranded cables are a reliable and flexible option for applications that require high flexibility and durability.
-
Unilay Strand:
Unilay Strad is a type of cable strand construction that consists of multiple wires or filaments of the same size and material twisted together in a helical pattern to form a cable. Unlike bunch-stranded cables, Unilay strand cables have a distinct central core wire around which the outer wires are twisted. Unilay strand cables are commonly used in power and control cables, overhead transmission lines, and marine cables, among other applications. The Compact design of Unilay strand cables allows for efficient use of space, making them a popular choice for applications where space is limited. Overall, Unilay strand cables are a reliable and durable option for demanding applications that require exceptional strength and resistance to abrasion and fatigue.
Factors to Consider When Choosing Strand Construction
When choosing strand construction for a cable, there are several important factors to consider. These factors include:
- Tensile strength: The strength of the cable is a crucial consideration when selecting strand construction. The cable must be able to withstand the forces it will be subjected to during use.
- Flexibility: the cable must be able to bend and flex without breaking or losing its shape. The strand construction chosen should provide the necessary flexibility for the application.
- Abrasion resistance: cables used in harsh environments may be subject to abrasion, which can cause damage to the cable. The strand construction should be chosen based on its ability to resist abrasion.
- Electrical properties: some applications may require the cable to have specific electrical properties, such as conductivity or resistance. The strand construction should be chosen based on its ability to meet these requirements.
