Solid Tinned Copper Wire 4 AWG
There are many types of 4 AWG electrical wire in the world that comes in solid, stranded and flexible versions depending on the amount of bare or tinned copper strands that it has. If one 4 AWG wire has more strands than another it means it’s more flexible plain and simple. When more strands are used to make a 4 AWG wire there will need to be more of them to equal out to the same outer diameter of a solid wire in order to transmit the same amount of current.
A 4 AWG wire is considered a 4 AWG wire when it falls into a certain outer diameter bracket which is a very small tolerance. The thickness of the insulation cannot be included in the outer diameter because the insulation is there for completely different reasons than the copper.
So, you have a solid tinned copper strand of wire without insulation and you need it to be more flexible. Obviously a 10 AWG solid tinned copper strand would bend easier than a 4 AWG correct? Even better, a 30 AWG wire would easily wrap around your finger so that would be the most flexible option. Any time you see a 4 AWG wire on the market using 30 AWG strands you’ll also notice that it takes 374 of those strands wound together to equal the same outer diameter as the single 4 AWG strand of tinned copper.
We sell both types of tinned copper electrical wire because we like to offer the available options to our customers. The single strand of solid tinned copper 4 AWG is used as a grounding wire so there’s no need for it to be flexible. There are also industries that like less flexible wires for installations in conduit and in walls of homes and buildings. A flexible wire would just bunch up when trying to push it through conduit creating many headaches.
Bus bar wire is another term for tinned copper. The process is that of using bare copper first and coating it with a layer of tin. It seeps through the copper making it look like silver or aluminum so if you’re unsure of the type make sure you consult an electrician or metal expert to examine it for you.
Please call us if you have questions about flexibility or the different types of insulation that can cover a 4 AWG tinned copper wire. Different types of insulation protect the copper against temperature and environmental conditions such as moisture, gasses, oils and chemicals.
