New energy cable It refers to the cable used to transport solar energy, wind energy, geothermal energy and other new energy. These cables have the characteristics of high temperature resistance, corrosion resistance, water resistance and fire prevention, and play an important role in the field of new energy. The following aspects need to be considered when selecting new energy cables:
1、 Cable type selection
For different types of new energy, appropriate cable types need to be selected. For example, solar crystal silicon cable and solar electric heating cable are generally used for solar cable; Wind power cables mainly include wind power cables, wind frequency converter cables, direct drive permanent magnet converter cables, etc; Geothermal energy cables include geothermal power cables, dual thermal power cables, etc.
2、 Cable specification selection
Economy and reliability shall be considered when selecting cable specifications. Generally speaking, the thicker the cable specification is, the stronger the transmission capacity of the cable is, but the higher the cost is. Therefore, it is necessary to comprehensively consider the actual situation and select suitable specifications.
3、 Selection of cable length and transmission distance
Cable length and transmission distance are important factors for selecting cable mode. In case of short transmission distance, direct laying can be adopted; However, the high-voltage direct current (HVDC) transmission mode is required for the occasions with long distance and high voltage level.
4、 Selection of environmental factors
When selecting new energy cable mode, environmental factors should also be considered. For example, cables used in the marine environment need to be anti-corrosion and seawater resistant; For cables used in extreme weather conditions, special cables resistant to high and low temperatures are required.
5、 Selection of transportation and installation mode
In actual use, transportation and installation methods should also be considered. Generally speaking, the cable length should not be too long to reduce transportation costs and installation difficulties. During installation, attention should be paid to the protection and protection of cables to ensure their safe and reliable operation.
In conclusion, when selecting new energy cable mode, it is necessary to comprehensively consider the cable type, specification, length, environmental factors, transportation and installation, etc., to ensure the safety, reliability, economy and rationality of the cable. At the same time, in practical application, it is also necessary to strengthen the supervision and maintenance of cables, reduce the cable failure rate and maintenance costs, and promote the further development of new energy.
