High Voltage Cable Market Growth Factor

Industrialization and Urbanization in Developing Countries

Industrialization and urbanization across the globe are increasing the demand for electric power. Therefore, an increase in demand for power would result in more power generation and transmission, leading to the increased requirement for high-voltage cables. Depleting fossil fuels such as coal and oil have attracted the attention of several governments to invest in renewable energy projects such as offshore/onshore wind farms, solar plants, and tidal power plants. The need for electrification in developing countries, such as China, Japan, and India, has led to the development of numerous renewable energy projects in the last decade. Therefore, the demand for high-voltage cables in power distribution centers and industries such as power utilities, oil & gas, and mining is increasing rapidly. The amount of power generated by renewable and non-renewable energy resources has increased over the past few years due to industrialization and urbanization.

Rise in Investment in Smart Grid Technology

Smart grids are preferred over traditional grid technologies because they are more dependable, adaptable, and cost-effective. Smart grids are overhauling and replacing old ones, increasing the demand for high-voltage wires. The State Grid Corporation of China invested $64 billion in smart-grid technology to improve its electrical networks and reduce carbon emissions. In addition, more than $100 billion have been invested by the Japanese government in the last decade in smart grid technology to upgrade their power generation transmission system and SCADA networks. These changes will fuel the demand for high-voltage cables in the coming year.

Market Restraint

Volatile Prices of Metals Such as Copper and Aluminum

Copper and aluminum are conductors found in high-voltage cables. The prices of these metals are crucial in determining the total cost of the high-voltage cable. As they are traded on a community-based exchange, the prices of these metals are highly volatile. Recently, inflation and rising demand for certain metals have driven their costs. Nearly the previous decade, the price of copper has soared by over 400%, from $0.77 per pound to $4 per pound. The volatility in the prices of these metals acts as a significant barrier to expanding the high-voltage cable business.

Market Opportunity
