We see a lot of installers coming to us after burning through cheaper PVC-insulated cable that cracks within a season or two, and the difference in core handling is immediately obvious—the tinned copper strands here don't corrode at the termination points like bare copper does, especially in coastal or high-humidity zones, so you're not chasing voltge drops form degraded connections a year down the road.
The 4mm2 cross-section is pretty much the sweet spot for string-level runs up to about 30 amps, and what you'll notice is XLPO insulation doesn't soften or deform when you're pulling it through conduit on a 40°C rooftop, it's actually stiff enough to keep its shape without being brittle.
TUV cerification to EN 50618 and 2PfG 1169 means the flame retardancy has been tested to IEC 60332-1, and the UV resisance is 25 years or so of direct exposure—don't use this for AC side wiring inside a building though, the 1.8kV DC rating is specifically for DC photovoltaic circuits, not general mains voltage.
Our batch documentation includes HPLC-grade COAs on teh crosslinking density and thermal stability data, which matters if your client requires traceability for insurance or warranty purposes—we usually hold about 2000m of JS-PV-4.0 in stock, but custom lengths (24-28 weeks lead time) need a confirmed order.
The overall diameter sits at 6.48mm with a 1.14mm insulation wall, and that conductor diameter of 2.59mm is actually tighter than most generic solar cables we've tested, meaning less copper waste per meter while still maintaining the rated ampacity—you'll find the weight at 48.7 kg/km is about 4% lighter than some competitors, which adds up on a 500m reel.
We typically start at 500 meters per size, but if you need less, just ask—we can sometimes do smaller trial orders.
Lead time is usually 7-10 working days for stock items. Custom lengths or packaging might add a few days.
Yes, we include test reports and the TUV certificate copy with every batch, so you have the paperwork for your project.
We only make this model with tinned copper stranded conductor—it's required for the TUV certification and UV/weather resistance specs.
Keep it in its original packaging, out of direct sun and moisture. It's UV-resistant, but long-term exposure before use isn't recommended.
