Stranded pure copper conductor core LSZH XLPE insulation and sheath solar cable with rated voltage 1.6/1KV

 

1.Application 

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 Kits.


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 commercial operations.


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.  (Note:  a 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 much less.
