A capacitor is an impassive dual-terminal electrical component used to store energy electrostatically in an electronic field. The arrangements of capacitors differ widely, but each one of them contains at least two electrical conductors detached by a dielectric, which is also known as an insulator. Capacitors are widely employed in electrical energy systems and appliances.
The basic working principle of capacitor used in an AC system provides lead to the voltage and it also provides reactive power addition which is often required to counter the reactive power absorption by the inductive devices.
Increasing demand for electricity is a major factor driving the expansion of this market globally, and the other factors such as reduction in transmission losses during bulk power transmission over long distances, supportive government regulations for energy trade and power grid interconnection, and moreover advancement in the technology are further fueling global demand for the capacitors. The increased power generation by renewable energy, and new technological up gradations from the power market, and the deteriorating environment favors the power transmission system up gradations increasing share of capacitors to used globally.
Some of the other factors such as increasing electricity demand in developing economies such as India, Brazil, and China, are expected to impact due to the enhance grid infrastructure, and increase the electricity accessibility to the region’s population. Additionally, the increasing demand from the various application industries, and regions are now generating several exciting opportunities for HV capacitors in the market. The emerging regions with high demand is Asia-Pacific which is projected to expand considerably due to the increasing investment in electricity sector, and the development of power transmission networks. In the APAC region, vast expanse of industrialization and urbanization has spiked power consumption capacities, moreover the distribution systems operating in the region is now adopting advanced technologies for reactive power compensation. Governments across several APAC countries are now inducing higher investment in their grid connection projects, while doing so, they are compelled to use efficient and reliable power transmission network systems.
However, the expansion of the global High voltage capacitor market is hindered by some factors such as the cost of raw materials. The manufacturing cost of the sub components such as plastic which is the most expensive material and increases the variable cost, thereby reducing the contribution margin in the overall capacitor manufacturing. In the recent years, capacitor manufacturers are declining to balance their raw material costs and component manufacturing costs, because they know that using a substitute raw materials can keep costs down and decrease the innovation. The critical requirement in capacitor manufacturing is its ability to hold a charge, which is determined by the existing surface area of the dielectric being used. Manipulation and innovations related to these dielectrics will impact the market in the future.
The HV capacitors market is represent significant potential for the end-users, manufacturers for the next decade. Some of key players include Eaton Corporation PLC, ABB Ltd, RTDS Technologies, Alstom SA, Maxwell Technologies Inc., Siemens AG., General Atomics, Inc., Sieyuan Electric and Samwha Capacitor Co Ltd.
