LB-145 current transformer manufactured by Shandong Taikai Instrument Transformer Co., Ltd. passed all type tests at KEMA laboratory in Netherlands, which means the successful acquisition of KEMA laboratory's highest grade gold certificate.

LB-145 current transformer is one of oil-immersed CT independently developed and manufactured by our company with outstanding electrical and mechanical properties. For the vertical type CT has a U-shaped primary winding and structure feature of long conductor circuit, then how to reduce the effect of the return conductor to the accuracy of the product and improve the withstand ability of short-circuit current on the product is the key to the product development process. Our technical R & D team has made important breakthroughs in the industry by using ansoft three-dimensional analysis software to accurately simulate and optimize the product's force and magnetic field distribution, to reduce the short-circuit current level of the product and to reduce the impact of the return conductor on accuracy. All technical indicators of the product are better than the requirements of the IEC standard.

The company successfully obtained the gold certificate for LB-145 product, which is the first international example of this type in KEMA laboratory. It highlights the consistent quality of our products, enhances the company's visibility in the international industry, and increases the product competitiveness in the domestic and foreign markets.
