Bare Stranded Wire

Definition

Bare stranded wire is an uninsulated electrical conductor composed of multiple fine wires twisted together to form a single strand. It is used in various electrical and mechanical applications due to its flexibility and conductivity.

Purpose

Bare stranded wire is utilized in electrical systems for its superior flexibility and conductivity compared to solid wire. It is often used in situations where the wire needs to be routed through tight spaces or subjected to movement and vibration. Its construction allows for better handling of mechanical stress and bending, making it ideal for connections that require frequent movement or adjustments.

Examples of Use

1. Electrical Grounding: Bare stranded wire is commonly used in grounding systems to ensure safe operation of electrical installations.
2. Automotive Wiring: The flexibility of stranded wire makes it suitable for use in vehicles where wiring needs to navigate through compact spaces and withstand vibrations.
3. Aerospace Applications: Stranded wire is used in aircraft due to its reliability and flexibility, ensuring stable electrical connections under dynamic conditions.
4. Power Distribution: It is used in power distribution networks to connect transformers, switchgear, and other electrical equipment.
5. Building Wiring: In some cases, bare stranded wire is used within conduit systems for specific electrical installations.

Related Terms

• Insulated Wire: Wire that is covered with a protective insulating material to prevent electrical leakage and protect against environmental factors.
• Solid Wire: A single, solid strand of wire, typically used where rigidity and resistance to corrosion are more important than flexibility.
• Tinned Copper Wire: Stranded wire that has been coated with a thin layer of tin to enhance its corrosion resistance and solderability.
• Flexible Conductor: Conductors made to maintain performance under frequent movement and bending, often using stranded wire construction.

Notes

• Bare stranded wire must be handled with care to avoid short circuits and electrical hazards, as it lacks insulation.
• It is essential to ensure proper termination and connection techniques to maintain the integrity and performance of the electrical system.
• When used outdoors or in harsh environments, additional protection such as conduit or weatherproofing may be necessary to prevent corrosion and mechanical damage.
