Current Transformer For Ring Main Unit Or Gas Filling Cabinet is a specialized measuring and protective component tailored for ring main units (RMU) and gas filling cabinets. Its core function is to convert high currents in RMU and gas filling cabinet circuits into standard low currents (usually 1A or 5A), enabling accurate measurement by electrical instruments and reliable protection by relays, thus safeguarding the safe and stable operation of these compact power distribution devices.
Crafted with high-quality magnetic materials and precision winding technology, it boasts excellent electrical performance, including high measurement accuracy, low error, and strong anti-electromagnetic interference capability. Designed to match the compact structural characteristics of RMU and gas filling cabinets, it features a small and lightweight structure, facilitating seamless integration and easy installation. It also has superior insulation performance and corrosion resistance, adapting to the sealed or semi-sealed operating environment of gas filling cabinets.
Widely applied in urban power distribution networks, industrial parks, and commercial building power systems equipped with RMU or gas filling cabinets, it provides critical data support for load monitoring, energy metering, and fault protection. As an indispensable component for ensuring the safe, efficient, and stable operation of these compact power distribution systems, it plays a vital role in modern urban power grid construction.
Distribution Current Transformer is a crucial measuring and protective component widely applied in low and medium-voltage power distribution systems. Its core function is to convert high currents in distribution lines into standard low currents (typically 1A or 5A) that are suitable for measurement by instruments and protection by relays, ensuring the safe and accurate monitoring of power distribution operations.
Crafted with high-quality magnetic materials and precision winding technology, this transformer boasts excellent electrical performance, including high measurement accuracy, low error, and strong anti-interference capability. It features a compact and robust structure, making it easy to install in distribution cabinets, switchgear, and other distribution equipment. Additionally, it has good insulation performance and thermal stability, capable of withstanding long-term continuous operation in harsh distribution environments.
Widely used in residential communities, industrial parks, commercial buildings, and other power distribution scenarios, it provides reliable data support for power load monitoring, energy metering, and fault protection. As an indispensable component for ensuring the safe, efficient, and stable operation of power distribution systems, it plays a vital role in modern power grid construction.
Company Profile
Nanjing Electric was founded in 1936 and is the first high-voltage ceramic manufacturer in the history of China's electrical industry. It is also the headquarters of Baiyun Group in the East China region. Nanjing Electric has been rated as one of the top 500 mechanical industrialization enterprises in China and a first-class industrial enterprise in China. At present, the base covers an area of 19 hectares and employs 1000+ people. The industrial base was put into operation with equipment in 2015. Nanjing Electric specializes in developing glass insulators, composite insulators, and ceramic insulator products. In 1958, China developed the first Tempered Glass insulator and condenser Bushing, filling the domestic gap. The company's products are exported to more than 120 countries and regions around the world, such as the Americas, Australia, the Middle East, Southeast Asia, and more than 50% of countries and regions in Europe. The main customers are national power grid companies or local power grid companies in various countries. The domestic market has achieved full coverage. The company's products are widely used in national strategic projects, including 33 UHV projects above 800KV. Our company is the largest insulator supplier in national engineering.
Nanjing Electric International Co., Ltd., formerly known as the Overseas Business Unit of Nanjing Electric Technology Group, established an international trade company in 2021 based on the development strategy of the group. With insulators and sleeves as the two flagship exhibits, the company actively carries out resource and multi-party cooperation around common values and market views. On the way to the world, international trading companies will firmly step forward and work hard for the century old white clouds and the world's white clouds.
The international trade team participated in international power exhibitions held in countries each year such as Germany, the United States, Brazil, Saudi Arabia, Egypt, India, Italy, Saudi Arabia, Australia, the Philippines, Thailand, Spain, Mexico, etc; Track the progress of key power projects in various countries; Further promote the internationalization process of products.
Facing the future, the company will focus on the needs of national power construction, seize the opportunities of new power infrastructure, ultra-high voltage projects, the "the Belt and Road" construction, and the development of green energy.
