The First Squeezing Submarine Cable System

The Prysmian Group announced the successful development and testing of the first 525 kV squeezing seabed cable system alang sa high-voltage DC nga mga aplikasyon.

In recent years, sustainable energy has been a hot topic and project. Sustainable energy development is worthy of everyone’s attention. So what is the close connection with the cable industry? Let’s take a look at the editor of the ZMS cable company.

According to reports, the breakthrough innovation of this cable technology will increase the maximum transmission capacity of the bipolar system to above 2.5GW, which is more than twice that of the current 320kV DC system.

A high-voltage DC cable connection is a key component of sustainable energy systems, which is used to transmit a large amount of electricity from a long-distance, which usually spans between countries or countries.

For this new voltage-level submarine cable system, the company uses its material knowledge and process capabilities to successfully cope with the challenge to optimize the reliable industrial process with strict technical parameters. And provide a complete system challenge.

About Sustainable Energy

Sustainable energy refers to a sustainable energy supply to meet the current needs without affecting the ability of future generations to meet their needs. Technology that promotes sustainable energy includes renewable energy, such as hydropower, solar energy, wind energy, wave energy, geothermal energy, and tide energy. It also includes technology that aims to improve energy use efficiency.

Green power is a subset of renewable energy and technology that provides the highest environmental benefits.

The U.S. Environmental Protection Agency defines green power as a source of electricity sources generated by solar energy, wind, geothermal energy, biogas, biogas, biomass energy, and low-impact small hydropower resources.

Green power is usually purchased by customers to avoid the benefits of environmental impact and the reduction of their greenhouse gas emissions.

Busa, the development of sustainable energy is inseparable from the development of the power cable industry. Each solar energy, wind energy, and geothermal energy has cable participation.

1. Power Cable And Solar Energy

Solar energy is the energy (mainly solar energy) from the celestial body outside the earth. It is the huge energy released when the hydrogen atomic nucleus of the solar is released at ultra-high temperature. Most of the energy required by humans comes directly or indirectly from the sun.

The fossil fuels such as coal, petroleum, and natural gas we need in our lives are formed by various plants to transform solar energy into chemical energy that can be stored in plants, and then formed by the underground animals and plants buried underground through a long geological age.

Advantage

1. Generality, no regional restrictions, whether it is land or ocean.
2. Harmic, will not pollute the environment. It is one of the cleanest energy.
3. Great, the total amount is the largest energy source in the world today.
4. Live, the energy of the sun can be said to be inexhaustible.

For solar photovoltaic cables, as far as photovoltaic applications are concerned, the materials used outdoors should be ultraviolet, oxygen, severe changes in temperature, and chemical erosion.
Using low-grade materials under this environmental pressure will cause the cable sheath to be fragile and even break down the cable insulation layer.

2. Power Cable And Wind Energy

Wind power generation is the kinetic energy of the wind to electrical energy.
As clean renewable energy, wind energy is getting more and more attention from countries around the world.

The number is huge, and the global wind energy is about 2.74 × 10^9MW. Among them, the available wind energy is 2 × 10^7MW, which is 10 times larger than the total amount of water energy developed on the earth.

Advantage

1. Clean, good environmental benefits.
2. Renewable, never exhausted, no greenhouse gas emissions.
3. Can be built on land or sea.
4. Low operation and maintenance costs.

Special cables (wind power generation cables) for wind power generation units, in addition to meeting the performance of ordinary cables, must also meet the less curved radius. The basic requirement of frequent reversal is that wind power cables are mostly used in areas with harsh climate conditions.

It is generally used in northern China. The climate is relatively cold and the temperature difference between day and night is large. Busa, wind power wires must also meet the conditions of the use temperature of -45 ° C ~+50 ° C, and the working temperature of -40 ° C ~+50 ° C.

3. Power Cable And Geothermal Energy

Geothermal power generation refers to the use of land thermal energy power generation.

The technologies used include dry steam power plants, flash steam power plants, and dual cycle power plants. Sa pagkakaron, 24 countries use geothermal energy for power generation, ug 70 countries use land heating.

Geothermal energy is natural heat extracted from the crust. This energy comes from lava inside the earth and exists in the form of heat, which is the energy of volcanic eruptions and earthquakes.
The temperature inside the earth reaches 7000 degrees Celsius, and the depth of 80 sa 100 kilometers drops to 650 sa 1200 degrees Celsius.

Advantage

1. Renewable
2. Broadly distributed
3. Rich reserves
4. Low unit cost

There are many tightly wrapped wires of geothermal cables. The heat conduction is strong, and the heat dissipation is fast, which improves the efficiency of the transformation of electricity into thermal energy and reduces energy loss. Ensure the safety and stability of the heating cable in use.

The superior insulation and moisture-proof performance of the multi-layer insulation layer use durable Teflon insulation layers, which to a greater extent prolong the service life of the cable.

The bronze line or tin-plated copper wire is a weaving radiation shielding net that can eliminate radiation, increase the mechanical strength of the cable, and play a role in grounding.

The rated output power design at the specified length provides consistent and reliable thermal output for easy selection and installation.

A single or multiple heating metal resistance conductor compositions, under the rated voltage, evenly generate calories in the conductor according to the ohm law. The rated power output on the rated length. Applicable to higher maintenance temperature requirements.

Summarize

The above is about close connections between cables and sustainable energy. With the rapid development of the world, the use of electricity is increasing, and various resources that can be used for sustainable use are being developed.

Cable is a necessary condition for power use, so demand is also increasing year by year.

ZMS cable companies have always paid attention to the development of cables and always insist on providing high-quality cables, cheap quality, thoughtful service, and products that are trusted after strict artificial qualification review.
