CXM-1300

The Hitachi CXM-1300 Outdoor Current Transformer (SKU: CXM-1300) is engineered for critical high-voltage applications within 345kV nominal systems. This transformer provides precise current measurement and robust insulation, essential for utility substations and industrial power transmission networks. It features a Basic Insulation Level (BIL) of 1300kV, ensuring superior protection against transient overvoltages, a vital characteristic for maintaining grid stability. The CXM-1300 offers a transformation ratio of 800:5 SR, with an exceptional accuracy class of 0.15 B1.8. This accuracy is maintained across a wide operating range, from 0.5% to 400% of its nominal current (4A to 3200A), ensuring reliable metering and protection even under varying load conditions. The transformer is designed with a rating factor of 4.0, allowing for operation at higher current levels than its nominal rating for extended periods. Furthermore, its 1-second thermal rating of 64kA rms demonstrates its capability to withstand significant fault currents without damage. Physical specifications include bushing creep and strike distances of 524mm and 149.6mm respectively, enhancing its performance and longevity in challenging outdoor environments. Manufactured in Japan (JP), the CXM-1300 embodies Hitachi's commitment to quality and reliability in high-voltage electrical equipment.
