New energy cable The conduction efficiency of is the loss of electric energy when it is transmitted in the cable. The improvement of conduction efficiency can reduce the waste of energy and improve the effect of power transmission. Here are some ways to enhance the transmission efficiency of new energy cables.
1. Select low resistance materials: the resistance in the cable is one of the main factors causing energy loss. Choosing low resistance materials as conductors of cables can reduce the loss of electric energy in the transmission process. For example, copper is a low resistance material that is widely used in the manufacture of cables.
2. Optimize conductor cross section area: the conductor resistance can be reduced by increasing the conductor cross section area. A larger conductor cross-section can provide a larger conductor surface area, thus reducing the concentration of current on the conductor surface, reducing the resistance of the conductor, and improving the conduction efficiency of the conductor.
3. Optimize conductor structure: conductor structure will also affect the resistance value. The use of multi strand thin conductors instead of single strand thick conductors can increase the flexibility of the conductor and provide a larger surface area to reduce resistance. In addition, conductor surface treatment methods such as silver plating and copper plating can also reduce resistance and improve conduction efficiency.
4. Select low consumption medium: select low consumption medium as the insulation material of the cable to reduce the energy loss caused by medium dissipation. Materials such as high density polyethylene (HDPE) and polyurethane (PU) have low dielectric loss and are suitable for new energy cables.
5. Optimize the cable structure: improve the cable structure to reduce the resistance and inductance of the cable, which is also an important measure to improve the conduction efficiency. For example, the use of oxygen free copper cable core and zinc oxide cable sheath can improve the transmission efficiency of the cable.
6. Control cable length: energy loss will occur in electric energy transmission, so the cable length should be controlled as far as possible when designing and wiring cables to reduce the energy transmission distance, so as to reduce energy loss.
7. Increase the insulation thickness: the selection of the insulation thickness of new energy cables will also affect the conduction efficiency. Properly increasing the thickness of the insulation layer can reduce the resistance and leakage current of the insulation layer and improve the conduction efficiency of the cable.
8. Reduce power supply voltage loss: In the process of long-distance transmission, the booster station can be used to boost the electric energy and then transmit it to reduce power supply voltage loss. Boosting voltage can reduce the transmission current, thus reducing the resistance loss of the conductor.
In order to further strengthen the conduction efficiency of new energy cables, relevant departments and research institutions can conduct more in-depth research and development, improve the materials and structure of cables, so as to continuously improve the conduction efficiency of cables, reduce energy losses and improve the effect of power transmission. This is of great significance for promoting the development and utilization of new energy.
