The LZZBJ9-12A1(A2) current transformer from Shen Zhen Chuang Yin Technology Co., Ltd. is an epoxy resin cast instrument transformer for 6.6 kV or 11 kV systems. Its fully enclosed support construction houses primary and secondary windings around an annular core within the resin body. The unit is rated for 50 to 60 Hz networks with a highest voltage for equipment of 7.2 kV or 12 kV, and meets the IEC 60044-1:2003 standard.
This model offers accuracy class combinations such as 0.2(S)/0.2(S), 0.2(S)/0.5, and 0.5/10P, with rated outputs of 10, 15, or 20 VA. It supports transformation ratios from 10-200/5 A up to 2000-3150/5 A. For a 600/5 A ratio, the short-time thermal current (Ith) is 50 kA/s and the rated dynamic current (Idyn) is 125 kA. The epoxy resin insulation provides resistance to moisture and harsh environments, allowing omni-directional installation.
These transformers are used for current measurement, energy metering, and protective relaying in electrical substations and industrial power systems. Power utilities, switchgear manufacturers, and engineering contractors source them for medium-voltage distribution networks. Buyers should confirm the exact transformation ratio, accuracy class combination, and secondary current (1A or 5A) required for their application before ordering.

Before ordering, verify the exact technical parameters your project requires: the rated voltage (6.6 kV or 11 kV), the transformation ratio, the accuracy class combination for metering and protection cores, and the secondary current (1A or 5A). Request the supplier's detailed technical data sheet and, if possible, a sample test report to confirm compliance with IEC 60044-1:2003.
Clarify the commercial terms directly with Shen Zhen Chuang Yin Technology Co., Ltd. Confirm the minimum order quantity, unit price for your specified configuration, and the lead time for production and testing. Discuss packaging standards to ensure the transformers are protected during sea freight from Shenzhen, and agree on the Incoterms (e.g., FOB Shenzhen or CIF your port).
Upon receipt, conduct an incoming inspection. Check the nameplate data against your purchase order. Perform routine tests as per IEC standards, such as checking the insulation resistance and verifying the transformation ratio and polarity. For critical applications, consider requesting a type test certificate from the supplier's laboratory.
