23/76 Insulated Cable F.T Cable BRB

23/76 Insulated Cable F.T Cable BRB insulated cable is a specific type of electrical wire. Specifically, its designation tells us about its construction. Therefore, understanding this cable helps in choosing the right wire for certain tasks. This guide explores the details of the 23/76 FT cable.

Decoding the “23/76 FT” Designation

The term “23/76” directly describes the cable’s conductor. Precisely, “23” indicates the number of strands within the conductor. Meanwhile, “76” refers to the gauge of each strand, according to the Standard Wire Gauge (SWG) system. SWG 76 represents a very fine wire (approximately 0.0076 inches or 0.193 mm in diameter). Consequently, combining 23 of these fine strands creates the final conductor. Furthermore, “FT” typically stands for “Flexible Tinned”. “Flexible” highlights the cable’s pliability due to its multi-strand structure. Additionally, “Tinned” suggests the copper strands have a tin coating.

Construction and Materials

Manufacturers construct this cable carefully. First, they bundle 23 fine copper strands together. Copper offers excellent electrical conductivity. Often, as the “FT” suggests, they apply a thin layer of tin over the copper strands. This process, called tinning, serves two main purposes. Primarily, it protects the copper from oxidation, especially in humid environments. Secondly, tinning improves solderability, making connections easier. Next, an insulating material covers the conductor core. Usually, manufacturers use Polyvinyl Chloride (PVC) for this insulation. PVC provides good dielectric strength. Moreover, PVC offers resistance to abrasion, moisture, and some chemicals.

Key Features and Benefits

The 23/76 Insulated Cable F.T. Cable BRB presents several useful features. Most importantly, its multi-strand design makes it highly flexible. This flexibility allows easy installation in tight spaces or where movement occurs. Secondly, the tinned copper conductor ensures reliable electrical performance and longevity. Furthermore, the PVC insulation provides essential electrical safety. It prevents short circuits and protects users from electric shock. As a result, this cable offers both convenience and safety for appropriate applications.

Detailed Specifications

Let’s examine the typical specifications for a 23/76 FT insulated cable.

• Conductor:
  • Stranding: 23 strands / 0.193 mm (equivalent to 23/76 SWG).
  • Material: Annealed Tinned Copper (or sometimes bare copper if not tinned).
  • Approximate Nominal Area: Around 0.67 sq mm (Calculated from 23 strands of 0.193mm diameter). Note: Always confirm the exact area specified by the manufacturer.

Common Applications

The flexibility of the 23/76 Insulated Cable F.T Cable BRB makes it suitable for specific uses. For instance, electricians frequently use it for internal wiring within electronic appliances and equipment. Also, it works well in control panels and switchgear wiring where flexibility is needed. Additionally, you might find it used in certain lighting circuits or for connecting small devices. However, always verify its suitability and current-carrying capacity for the intended application.

Choosing Your Cable

Selecting the right 23/76 FT cable ensures performance and safety. Therefore, choose cables from established manufacturers known for quality. Always check that the cable’s specifications match your project’s requirements. Ultimately, using a high-quality, correctly rated cable is essential for any electrical work.

In conclusion, the 23/76 FT insulated cable is a flexible and functional wire defined by its specific strand count and gauge. Its tinned copper conductor and PVC insulation make it suitable for various low-voltage, flexible wiring applications. Consequently, understanding its properties helps ensure you use it safely and effectively.
