High temperature wire products are based on the type of insulation that covers the copper strands not the copper itself. Basic lead wire insulation is PVC which is typically rated up to 105°C. When you upgrade to PTFE from PVC insulation it’s rated up to 200°C. Bare Copper Bare copper strands are used in both PVC […]
THHN is designed much different than welding cable because they’re used in different applications that will affect the cable in different ways. They can both be used outdoors but THHN can be used in conduit while welding cable cannot. Welding cable is also handled by the user more frequently compared to THHN wire that is […]
There are three strong price drivers for PTFE wire which are copper, silver and PTFE compound that each affect the price of PTFE hook up wire. Copper and silver are both commodities traded on the NYSE which will change the price daily making it difficult for suppliers to price their high temperature wire. PTFE started […]
Finding an electrical wire 2/0 size in a flexible version is not that difficult when you understand why each cable is flexible or not. Electrical wire is a common tern used for THHN building wire which is not very flexible at all. It’s more flexible than a solid strand of 2/0 copper because the strands […]

Southwire is one of the biggest manufacturers of TFFN wire which is available in 16 AWG and has the nylon coating. 1. TFFN = Thermoplastic Flexible Fixture Nylon […]
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 […]
The two types of welding cable in the industry have different approval ratings and stranding options. There is a class K stranding and a class M stranding which determines how flexible the cable will be in the application.

ROMEX® is a brand name by Southwire Company which is their very popular type of NM-B cable. Yes, Romex® is very similar to knock off brands of NM-B cable and the description of it would be Non-Metallic electrical cable. Similar items in different industries would be “Kleenex” compared to a similar competitive brand of tissues […]
Copper wire prices are based on the current cost of copper per pound on the NYSE. It’s traded daily and determines the base copper pricing for most types of wire and cables. Of course, other factors of insulation, shielding and engineering need to be factored in after the base price of copper. Electrical wire consists […]
For the most of 2012 copper prices have been pretty steady in the $3.50 to $4.00 per pound range. Copper pricing had been in the high $4′s throughout most of 2011 until the end of the year when it started to drop quite a bit. Copper has literally been a hot commodity over the past 5 years […]
