Stranded cable
Kablar inkluderar strängade eller fasta kablar. Valet av att använda strängad eller fast kabel beror på flera faktorer, som typ av applikation och projektmiljö. Att välja rätt typ av kabel kan hjälpa till att göra projektets kabling mer logiskt.
Stranded cables have a conductor made up of several wires twisted together and then wrapped in an outer jacket. Typiskt, this type of cable can be identified by its specification. Till exempel, a 7 x 12 cable indicates a cable with 7 wires of 12 gauge stranded together.
Stranded wires are very flexible and have a high resistance to metal fatigue. Typiskt, stranded wire is the product of choice for printed circuit board manufacturers. This is because the use of solid wires in this type of application places greater stress on the circuit during manufacturing. Stranded wires are also widely used for computer mouse cables, welding electrode cables and AC power cables.
A solid cable has a single solid copper wire as the conductor. It is used for permanent base links between two wiring centers or between a wiring center and a distribution box. This type of cable has low attenuation and is less expensive. Typiskt, solid cables are used for horizontal and vertical structured cabling and should not be bent once installed.
1. Flexibilitet. Solid cables are less flexible, while stranded cables are more flexible. Solid cables have a tendency to break if repeatedly bent. Dock, when terminated with stranded wires, the individual conductor wires will break or loosen over time. Däremot, solid wires always retain their original shape. Sammanfattningsvis, use solid wires in a stable wiring environment and stranded wires in more curved or confined spaces.
2. Yield. Higher (thinner) gauge numbers have higher losses than lower (thicker) gauge numbers. Således, stranded cables have 20% till 50% more attenuation than solid copper cables (solid copper cables). Dessutom, stranded cables also have higher DC resistance than solid cables due to the presence of air in the conductors. Overall, solid core cables are better current conductors and provide excellent and stable electrical characteristics..
Although the more strands of stranded wire in a wire, the better the flexibility, the number of strands affects the price – the more strands that make up a cable, the more it costs. To keep costs down, Category 6 and Category 6A stranded cables are designed to have a sufficient number of strands to maintain proper flexibility, but not enough to make a huge price difference. In other words, the added cost of choosing stranded cable (cable trenzado)in environments and applications where solid cable is not appropriate is not enough to risk compromising performance or standards compliance in favor of solid cable. Always use stranded cable in controlled areas of the environment where greater flexibility is needed!
