Pure Copper Core Solar Cable
Stranded pure copper conductor core LSZH XLPE insulation and sheath
solar cable with rated voltage 1.6/1KV
Applied to solar panels for power generation and related components
of the wiring, connection, particularly suitable for outdoor .
Resistance to sunlight, anti-aging , Using the low smoke
halogen-free flame retardant materials, higher grade, more safety .
This stranded copper core wire is perfect for many different
applications within a PV solar power system. The wiring can easily
be stripped, allowing it to be used with MC4 Connectors and battery
rings. Adding an MC4 connector to one end will create an adaptor
kit, or adding it to both ends will create an extension cable.
Affixing battery rings will allow the copper wiring to substitute
as a tray cable. This handy, versatile Stranded Copper Wire offers
a variety of solutions for all systems, particularly Off-Grid Cabin
2. Why to choose copper material as the conductor?
Aluminum or Copper: The two common conductor materials used in
residential and commercial solar installations are copper and
aluminum. Copper has a greater conductivity than aluminum, thus it
carries more current than aluminum at the same size.
Aluminum may be weakened during installation especially during
bending, however it is less expensive than copper wires. It is not
used (not permitted) for interior home wiring, as they are used in
larger gauges for underground or overhead service entrances and for
3. Which type of wire is good for AC and DC current: solid-core,
single-strand wire or stranded wire?
Either is fine. While it is true that at very high frequencies,
solid conductor wire shows increased impedance due to eddy current
forcing the current to the outside, aka the skin effect, that is
not the case at 60Hz and common wire sizes. (Notea useful
approximation for the wire diameter where the resistance increases
by 10% is Dw = 200/sqrt(f), with f in Hz and Dw in mm. So for 60
Hz, Dw is 25.8, or just over an inch.)
The reason that we use stranded versus solid wire in our day to day
lives is that solid wire is cheaper, but does not put up with the
constant flexing of power cords. So, we have solid core wire in our
walls where it does not need to move, but cost matters, and
stranded wire in our power cords where a solid wire would quickly
work harden, embrittle and break.
Now, as to why the solid wire would work harden, embrittle and
break, you need to understand that the strand diameter relative to
the bend radius is what determines how much strain is imparted into
the wire. Solid wires have large strand diameters and see lots of
strain. Stranded wires have strands with small diameters and see
