“Xinchangda delivered our 2,000‑unit CT order in 12 days, with accuracy better than 0.2 S. The on‑site calibration support saved us 3 weeks of testing.” – James Liu, Procurement Manager, Siemens USA
“Their ISO 9001 and RoHS compliance documents were accepted without any audit delays, allowing us to launch our solar inverter line ahead of schedule.” – Maria Gonzales, Technical Director, Tesla Energy
Certifications: CE, UL, FCC, GS, CB, RoHS, IEC 61869‑2, ISO 9001, VDE, SAA
Most utility‑grade CTs are offered in 0.2 S, 0.5 S, and 1.0 S classes per IEC 61869‑2. For protective relaying, 0.2 S is recommended.
Yes. Our engineers can design CTs with burden from 0.5 VA up to 20 VA, matching your meter or relay specifications.
Standard production and DDP shipping takes 14 days. Express air freight is available within 5 days for an additional surcharge.
Every batch is tested in our ISO‑9001 lab and comes with a calibrated test report (traceable to NIST standards).
We accept T/T (30 % deposit, 70 % balance), L/C at sight, and PayPal for sample orders. Credit terms can be negotiated after the first successful shipment.
