Development trajectory
The manufacturing technology of power capacitors has gone through several stages of development. From the perspective of capacitor constituent materials and packaging forms, there are the following three main forms: A. The oil-immersed type appeared in the 5. and 1960 s of the last century is a generation of low-voltage capacitors. Its structure uses oil-immersed capacitor paper as the medium, the capacitor elements are flat components, and the liquid medium uses mineral oil (PCB toxic components), etc. The product has large loss (0.2-0.6) and large volume, short service life. B. 7. the 1980 s, with the application of metallized film instead of capacitor paper, capacitors have a flat to circular structure, with self-healing performance and product performance.
The manufacturing technology of power capacitors has gone through several stages of development, from the capacitor material and packaging form to see the following three main forms:
A. The oil-immersed type that appeared in the 5. and 1960 s of the last century is a generation of low-voltage capacitors. Its structure uses oil-immersed capacitor paper as the medium, the capacitor element is a flat element, and the liquid medium uses mineral oil (PCB toxic components), etc. The product has large loss (0.2-0.6%), large volume and short service life.
B. 7. the 1980 s, with the application of metallized film instead of capacitor paper, capacitors have a flat to circular structure with self-healing performance. The performance of the product is greatly improved and the volume is reduced, which is about 1/3 of the first generation of products. The liquid medium also began to use minerals or resins, and the active loss was reduced (0.125%).
C. In the 1990 s, European manufacturers began to introduce three generations of low-voltage capacitors with cylindrical structure. Metallized films were used inside the components, and natural oil or resin was filled and sealed in aluminum shells. The volume was reduced and the loss was reduced to 0.3W/kvar.
Up to now, with the development of technology, SPLEND Company has begun to develop in the direction of miniaturization, oil-free and environmental protection. It adopts metalized film inflatable technology and mixed resin, and has built-in unique safety protection device. The discharge time is accelerated by 20 seconds to reach below 50V, thus realizing the revolution of medium and the service life is more than 15 years. Development into a new generation of dry structure, explosion-proof, safe, environmentally friendly power capacitors.
As early as more than a decade ago, Europe recognized the harm of power grid harmonics to damage and interfere with the safety of the power grid and the normal operation of related electrical equipment, and formulated mandatory regulations. Basically, only reactive power compensation devices with series detuning reactors are allowed to be installed. Practice has proved that the cost of reactive current is significantly saved, the load of conductors, fuses and transformers is reduced, harmonic current and harmonic voltage are reduced, and the use of power grid resonance and power supply grid are more reliable!
SPLEND has developed reactive power compensation products for modular devices to meet market demand;
In the 1990 s, the development of industry and power quality requirements introduced dynamic filter compensation devices and high-voltage reactive power compensation products;
2000 years after the development of electrical update widely promoted thyristor switching device is widely used;
SPLEND has developed active filters for power electronics;
Established an office in Beijing, China in 2007;
In 2009, Sberland Electric (Beijing) Co., Ltd. was established;
2011 to establish a laboratory in China-Beijing Zhongguancun Science Park;
Sales system:
Our agents around the world, professionally qualified employees will provide customers with information and consultation on products and applications locally. The sales and marketing department will be committed to the technical update of product development according to the customer's requirements. Customer satisfaction is the primary direction of our efforts.
