Increasing global energy demand will become one of the key factors driving the growth of the high-temperature cable market during the forecast period. Due to strong global economic growth, global energy consumption has increased. Most of the energy demand comes from China, the United States and India. This factor has led to an increase in the number of power plants and transmission lines that are important end users of high-temperature cables.
The upcoming high-temperature cable market trends, such as the increase in HVDC devices, will also drive market growth during the forecast period. Compared with AC cables with distance limitations and transmission capacity limitations, high voltage direct current (HVDC) cables have more advantages. Important applications of HVDC cables are to connect remote power generation, interconnect power grids, offshore wind power connections, DC links in AC power grids, overhead transmission lines, etc. Therefore, as the installation of new HVDC projects increases, the demand for high-temperature cables will continue to rise during the forecast period, thereby promoting the growth of the high-temperature cable market.
From the perspective of the application market, the energy sector is the largest end user of the market in 2018 and the largest high-temperature cable market share during the forecast period. Due to the increase in global energy demand and the massive development of wind power generation, the ever-increasing power generation capacity and transmission and distribution network will drive market growth in the next few years.
From the regional market perspective, the Asia-Pacific region will account for the highest share of high-temperature cables throughout the forecast period. Factors such as the significant growth of the end-user industry and the rapid growth of exploration and production activities are promoting the growth of the high-temperature cable industry in the region.
What is a high temperature cable?
A high-temperature cable is a cable whose conductor material is a multi-strand soft copper conductor. Heat-resistant and high-temperature wires and cables are generally determined by two requirements. The first is the high ambient temperature of the wire and cable, and the cable can normally transmit signals or electric energy under high temperature for a long time; the other is the power transmission cable, which is mainly aimed at increasing the interception capacity.

Cable working in high temperature environment. Ordinary cables are prone to insulation aging and scorching at high temperatures, and the use of cables loses performance, is damaged and cannot be used. The high temperature cable can work normally and stably under the rated high temperature, the signal or power transmission performance is not affected, and the cable has a long service life. This type of functional cable is the most common and most common type of high-temperature cable, and its use characteristics are also the easiest to understand.
The load-increasing high-temperature cable is mainly developed to reduce the outer diameter and weight of the cable under the prerequisite of current-carrying, and to develop towards light weight. Generally speaking, the higher the working temperature of the cable, the greater the current carrying capacity of the cable of the same cross-section. In occasions such as airplanes and automobiles, weight reduction is of great significance, and the use of high-temperature cables greatly reduces the cross-section. When the operating temperature rises from 90°C to 155°C, the current-carrying capacity increases by 50%. Under the same current-carrying capacity, the weight of the cable is reduced by half and the cost is also reduced. Of course, while the current is high, the power loss of most insulating materials will also increase
