Got your RFQ on the 1000mm2 — we’ve supplied quite a few of these YJLW03 cables to power station projects over the years, and I can tell you straight up they handle the 76/132kV load without much fuss. The bare copper conductor is stranded circular or segmental Milliken style, which keeps the conductivity tight and bending radius manageable at 51 inches for installation and 34 inches once it’s in place.
You’re probably wondering about insulation and sheathing — the XLPE is extruded with semi-conducting layers on both conductor and insulation screens, roughly 122 mils thick, so dielectric strength is solid for those high voltage applictions. Outer jacket’s PE, black as you’d expect, and the overall diameter comes in at about 2.80 inches, give or take a few mils depending on the run.
One thing that catches buyers off guard is the capacitance — 64.51 pF/ft, and charging current of 1.62 A per thousand feet, which matters for line length and reactive power planning. If you’re running long underground feeds, you’ll want to factor that into your system design; it’s not a dealbreaker, but it does affect losses.
Weight’s another point — copper conductor and screen comes to 6.04 lbs per foot, or 3.99 lbs if you go with aluminum conductor instead. For a 1000mm2 cable, it’s a bit of a beast to pull, so plan your cable trays or trench spacing accordingly. Most buyers go with copper for conductivity, but aluminum saves on weight and cost.
We usually have stock on the 1000mm2 size, though lead time for custom lengths is about 20 days or so — (check with us on urgency). Just need to confirm if you want copper or aluminun conductor, and whether PVC or PE sheath; PE is standard for underground runs, but we can do PVC if that’s your spec.
Anyway, shipping’s on 1,000-meter drums or as cut lengths if you prefer, with full COA and ISO certs. We’ve got a couple orders for a substation expansion heading out next month, so that should tell you it’s proven for — not ideal for residential or light commercial due to the size and votage rating, but for power stations it’s exactly what you need.
Typical MOQ for this cable is 500 meters, but we can adjust based on project needs. Let us know your required length for a custom quote.
Standard lead time is 4-6 weeks from order confirmation. Rush orders may be possible depending on current production load.
Yes, we can supply ISO, CCC, and CE certificates along with the shipment. Just let us know which documents you need for your compliance requirements.
Absolutely – we offer both copper and aluminum conductor options. The copper version weighs 6.04 lbs/ft, while aluminum is lighter at 3.99 lbs/ft.
During installation, the minimum bending radius is 51 inches, and for permanent installation it's 34 inches. Follow these to avoid damaging the insulation.
