Введение
Wire comes in two basic constructions: solid and stranded. Each has distinct advantages and ideal applications.
Solid Wire Characteristics
Solid wire consists of a single conductor:
- Single conductor construction
- Stiffer and holds shape well
- Best for permanent installations
- Generally lower cost per foot
Stranded Wire Characteristics
Stranded wire consists of multiple thin conductors twisted together:
- Multiple thin conductors twisted together
- More flexible and easier to route
- Better resistance to vibration and flexing
When to Use Solid Wire
Solid wire is ideal for permanent, fixed installations.
Совет
Solid: In-wall wiring, conduit runs, permanent installations. Stranded: Flexible connections, equipment leads, areas with vibration.
When to Use Stranded Wire
Stranded wire excels in flexible applications:
- Equipment connections requiring flexibility
- Areas subject to vibration
- Portable equipment and cords
- Larger wire sizes (easier to work with)
Current Capacity
Both solid and stranded wire of the same AWG have the same current capacity.
Важно
Some terminals and connectors are designed for solid wire only. Always verify compatibility before installation.
Заключение
Choose wire construction based on your specific application. Both types perform equally well electrically when properly sized and installed.
