BSMJ(Y) Series Three-Phase Compensation Three Phase Cylinder Power Factor Capacitor

As a leading enterprise in the Chinese power capacitor industry, Geyue Electric has gained a reputation worldwide based on its over 20 years of dedicated research and manufacturing experience in the field of low voltage reactive power compensation. Dedicated in R&D, production and sales, our company possesses advanced international automated production lines and a laboratory certified by CNAS. Our products have received numerous international authoritative certifications, such as the CE certificate issued by the EU certification body. Our production line has an annual capacity of 500,000 units and is exported to 28 countries and regions. Especially in the countries along the "Belt and Road" initiative, Geyue capacitors have become the designated brand for several oil and gas projects. Our core product - the BSMJ(Y) series three-phase compensation three-phase cylindrical power factor capacitors, adopt the fifth-generation metallized film technology and innovative structural design, perfectly integrating the three core advantages of high reliability, energy-saving efficiency and ultra-long service life. So far, the BSMJ(Y) series power factor capacitors have set a new industry benchmark in the field of power quality improvement. It is worth noting that in a large-scale natural gas processing plant project in the west, the BSMJ(Y) series capacitors provided by our company operated continuously for over 60,000 hours without failure, helping our client increase the power factor from 0.68 to 0.96, and saving an annual electricity expense of 3.2 million yuan.

This series of power factor capacitors is based on the "three protection and one self-healing" technology platform independently developed by Geyue Electric (explosion-proof, moisture-proof, corrosion-proof + intelligent self-healing). Through rigorous accelerated aging tests and extreme environment validations, the products ensure stable performance under various complex working conditions. Currently, Geyue Electric’s power capacitors have been successfully put into application in power systems across 40+ countries and regions worldwide, with a cumulative total of over 500,000 sets of reactive power compensation devices. They have established an outstanding market reputation in key fields such as industrial automation, commercial buildings, and new energy power generation. Particularly in industries with strict requirements for power quality, such as steel smelting, automotive manufacturing, and data centers, the failure rate of Geyue Electric’s power factor capacitors remains at the lowest level in the industry, and the customer retention rate is as high as 92%. The following are main technical advantages of this series of power factor capacitors:

The metallized polypropylene film (MKP) of BSMJ(Y) series power factor capacitor produced by Geyue Electric uses a high-purity evaporated aluminum-zinc alloy layer as the electrode. During local breakdown, this electrode can instantly vaporize and isolate the fault point, automatically restoring the insulation performance and preventing the overall failure of BSMJ(Y) power factor capacitor. In addition, inside this power factor capacitor, there is a pressure separation device for explosion prevention. When overpressure occurs, the safety valve at the top of the shell disconnects to prevent the risk of explosion. Most important, this BSMJ(Y) series power factor capacitors have strong heat resistance and are made of special dielectric materials, which can operate stably in an environment ranging from -25℃ to +70℃, adapting to any harsh industrial conditions.

The BSMJ(Y) series power factor capacitors of Geyue Electric have extremely low loss (tanδ ≤ 0.2W/kvar), and their dielectric loss is much lower than the national standard (GB/T 12747). This reduces the self-energy consumption during reactive power compensation and achieves remarkable energy-saving effects. This series of power capacitors has a compact cylindrical structure, with a higher capacity per unit volume, significantly saving the space in the distribution cabinet. It effectively reduces the reactive power loss in the power grid, increases the power factor to above 0.95, avoids fines from the power supply bureau, and can reduce the electricity cost by 5% to 15%.

The BSMJ(Y) series power factor capacitors of Geyue Electric adopt anti-oxidation materials and vacuum impregnation technology, which delays aging and extends the service life by more than 30% compared to ordinary capacitors. This series of capacitors can operate without maintenance. Their self-healing properties and dry-type structure without electrolyte reduce the need for manual intervention and eliminate the need for regular coolant replacement. The capacitance decay rate of this capacitor is low (≤ 2% per year), and the capacity decays slowly after long-term operation, ensuring a stable and long-lasting compensation effect.
In summary, from the perspective of core technologies, the main technical advantages of Geyue Electric's BSMJ(Y) Series Three-Phase Compensation Three Phase Cylinder Power Factor Capacitor are as follows: In terms of the reliability of the capacitor, Geyue Electric uses military-grade raw materials and special processing techniques, resulting in a failure rate of less than 0.5% per year; in terms of the energy efficiency performance, Geyue Electric's innovative development of low-loss dielectric formula has reduced the operating loss of the capacitor by more than 30% compared to conventional products; in terms of the service life of the capacitor, Geyue Electric extends the product design life to 120,000 hours through unique anti-aging design and stress elimination structure, which far exceeds the industry average of 80,000 hours. These breakthrough technical advantages make Geyue Electric's power factor capacitors the preferred solution for smart grid construction and industrial energy-saving renovation.
