We've got the YJJJI series in stock for the 240-3000mm² range, usually ships within 10 working days or so—though the 220kV variants might need a bit longer if we're out of a specific silicone rubber batch.
The partial discharge stays at or below 5pC at rated voltage, which is tighter than what most buyers expect for bulk transmission gear, and the 0.25±0.01MPa sealing pressure holds steady through the 1-hour test (check the COA for your specific voltage grade).
One thing we see a lot is concern about thermal cycling performance, and 20 cycles is pretty standard here—actually, most buyers don't push beyond that unless they're doing custom qualification work.
grey silicone rubber body handles the 90kV-318kV power frequency withstand for 30 minutes without issue, but it's not really suited for continuous outdoor UV exposure without addtional jacketing—just something to keep in mind if your insallation is above ground in direct sun.
Lightning impulse withstand ranges from 450kV to 1050kV depending on the voltage rating you're targeting, and radio interference at 1MHz stays under 500μV, which is better than reagent-grade components we've tested form other suppliers.
38/66kV units ship in standdard plywood crates with foam inserts, but the 127/220kV stuff goes out in custom steel-reinforced boxes—lead time on those is typically 15 days or so, and our company can include the TDS and SDS with the shipment.
Our standard MOQ is 50 sets per size, but we can be flexible for first-time orders—just reach out to discuss.
Lead time typically runs 30-45 days, depending on the total quantity and specific sizes. We'll give you a confirmed timeline once we have your order details.
Yes, we include IEC 60502 and GB/T 11017 compliance certificates with every shipment, plus detailed test reports for partial discharge (≤5pC), lightning impulse withstand (450kV-1050kV), and all other parameters.
We can adjust the color upon request, but the sealing pressure of 0.25±0.01MPa/1h is fixed to meet standard requirements. For other modifications, let's talk—we'll see what's possible.
Store them in a cool, dry place away from direct sunlight and ozone sources, ideally between 10°C and 30°C. Keep them in their original packaging to avoid contamination that could affect the ≤5pC partial discharge rating.
