The new energy wave is coming in 2024. How can the cable industry ride the wave?

In 2024, the scale of new energy construction projects will reach a new high, with the total construction volume for the year reaching 28 million kilowatts. Among them, 7.13 million kilowatts of photovoltaic power generation projects, 1.91 million kilowatts of energy storage projects, 13.55 million kilowatts of wind power projects, and 11 million kilowatts of new energy vehicle battery swapping projects.

The new energy wave is coming. As an important part of power transmission materials, the cable industry will also usher in a new round of growth. But opportunities and challenges coexist, along with fierce competition and escalating market demands.

Taking photovoltaics as an example, China, the United States and Europe are the three regions with the largest newly added photovoltaic installed capacity, accounting for 43%, 28% and 18% of the global total respectively.

The rapid development of the photovoltaic industry has caused the demand for photovoltaic cables to continue to expand. Photovoltaic cables are wire and cable products used to transmit current or signals. They are mainly used in DC circuits in the negative grounding device of the power supply system. Its voltage level is usually 0.6/1kV or 0.4/0.6kV, and some are as high as 35kV.

Some industry insiders said: "With the advent of the parity era, the photovoltaic industry is about to enter a stage of explosive growth. In the next 5-8 years, photovoltaics will become one of the world's most important sources of electricity." "photovoltaic cables" as an important part of the photovoltaic industry chain have very broad development prospects in East China. Cable, relying on 25 years of cable R&D and production experience, takes high-quality development as the starting point in all aspects of materials, processes, performance, services, etc., and continues to provide the market with good cables."

The “sudden rise” of the energy storage industry cannot be underestimated. The energy storage industry is developing rapidly, and its rapid development is inseparable from the promotion of the "dual carbon" goal and the advancement of lithium battery technology. The demand for high-voltage DC cables, which are mainly used to connect the charging and discharging equipment and control equipment of energy storage power stations, and medium and low-voltage AC cables, which are used to connect transformers, distribution cabinets, lighting, control and other low-voltage equipment in energy storage power stations, will also increase significantly. Increase.

Although "the scenery here is unique", the rapid development of new energy has also put forward higher requirements for the cable industry.

On the one hand, with the great development of new energy, the performance of traditional cable products has been unable to meet the needs of the new energy field. For example, in the photovoltaic field, due to the influence of ground construction, cable trenches will be restricted and the space will be cramped; direct sunlight will increase the surface temperature of the cables, thereby affecting the service life of the photovoltaic modules. In response to these problems, it is necessary to develop photovoltaic module bracket cables more suitable for flat roofs, solar cell module lead-out cables suitable for fixed installation, tension pay-off trolley cables suitable for tracking systems, and charging pile cables with better high temperature resistance.

On the other hand, the promotion and application of new technologies and new materials will also change the competitive landscape of the cable industry. For example, the promotion of hydrogen energy vehicles will drive the demand for cables related to charging piles; the large-scale high-density cabling of wind power will promote the growth of demand for special cables such as tight-buffered stranded aerial cables and composite winch aerial cables; and the development of submarine photovoltaic complementary resources Utilization will drive the growth in demand for special cables such as float cables and observation optical cables.

In recent years, the concept of green environmental protection has been deeply rooted in the hearts of the people, and environmentally friendly wires and cables that are flame-retardant, halogen-free, low-smoke, and low-carbon are increasingly popular in the market.

Green development has become a global consensus, and electricity, as a basic industry of the national economy, will inevitably develop in a green and low-carbon direction.

The pace of research and development of flame-retardant, halogen-free, low-smoke, low-carbon and environmentally friendly special cables will be further accelerated. As an important component of smart grid terminals In part, cable products must meet various application environments and performance requirements. We will design different cable solutions according to different usage scenarios. For example, charging pile cables for outdoor use need to be more resistant to high temperatures.

A new round of changes is brewing

At present, the domestic cable industry is still facing a situation of overcapacity and fierce competition among homogeneous products. In the future, the cable industry will conduct more in-depth exploration and practice in the direction of green development. Reduce the carbon emissions of products by improving materials and processes; develop special cable products with higher added value to meet the needs of specific scenarios; create intelligent and digital operating models to enhance the competitiveness and profitability of enterprises and promote The coordinated development of upstream and downstream enterprises in the industrial chain will ultimately achieve the goal of high-quality development.
