Highest Quality Materials
We strive to provide the highest quality phase converters possible. In order
to do this we make sure to use the best materials available. That is why we use
only 100% copper wound generators in our products. Copper has long been one of
the top industry metals due to its overwhelming advantages in the electrical
field. Copper outperforms the competition in almost all measurable comparisons.
Copper v. Aluminum
Copper sets the standard on todayís electrical conductivity charts. Only silver
is rated more conductive. Aluminumís electrical capacity is a mere 64.9% as
conductive as copper; limiting its overall amperage capacity. Ex. 90°C
12awg Copper wire in free air = 40 amps vs. 90°C 12awg aluminum wire in free
air = 30 amps. Thatís a 25% difference.
Copper is a superior choice over aluminum is its ability to work with a multitude
of connection types. Aluminum has experienced difficulties in this particular
area. When left exposed to the atmosphere, aluminum will develop a hard, tough oxide
film on its surface. While this film may protect the aluminum from further
corrosion it creates a problem for the connections to which it attaches. The oxide
layer that forms is a good insulator and therefore raises the resistance between
the connection terminals and the aluminum surface, eventually overheating the
connections and causing failures. Although copper will also react to the atmosphere
and oxidize; the thin layer that does form is conductive, eliminating this problem.
The inability for aluminum to compete with copper in conductivity causes
manufacturers to overbuild aluminum wound units to compensate; creating a unit that
requires a significantly larger footprint. This need to over build the units also
tends to take away from one of the only significant advantages of aluminum: weight.
Per foot aluminum does weigh significantly less, but the more you add on top of it
to try and match coppers conductivity the more it weighs, thus reducing any advantage
it may have had.
As we continue to provide the highest quality products we will use only the best
materials available. Copper has proven itself countless times in the past and is
still considered the top end material in our industry. With that in mind, rest
assured that all Ace Phase Converter units will be provided with 100% electrical
grade copper wound generator units.
