As an important carrier of power transmission, the design of High Voltage Cable must meet the stringent requirements of high voltage and high current transmission. In order to ensure that power is delivered to the destination safely and efficiently, the designers have adopted a number of key technologies in the research and development and manufacturing process of High Voltage Cable.
First of all, the conductor design of High Voltage Cable is crucial. The conductor must be made of materials with high conductivity, such as copper or aluminum, and the resistance can be reduced and the current transmission capacity can be improved by optimizing the conductor structure, such as twisting multiple strands of fine wires. At the same time, the conductor must also have good water resistance to ensure the stable operation of the cable in harsh environments.
Secondly, the design of the insulation layer is also critical. The insulation layer of High Voltage Cable must have excellent electrical properties and heat resistance to withstand the electric field strength and heat generated by the current under high voltage. Common insulating materials include cross-linked polyethylene, polyvinyl chloride, etc. These materials not only have high insulation resistance, but also maintain stable performance at high temperatures.
In addition, the design of the shielding layer and armor layer is also an indispensable part of High Voltage Cable. The shielding layer can reduce the interference of the electric field on the surrounding environment and improve the anti-interference ability of the cable; while the armor layer can enhance the mechanical strength of the cable and prevent external forces from damaging the cable.
In summary, the design of High Voltage Cable needs to comprehensively consider multiple aspects such as conductor, insulation layer, shielding layer and armor layer to meet the needs of high voltage and high current transmission. By adopting advanced technology and materials, High Voltage Cable can ensure the safe and stable transmission of electricity, providing strong guarantee for the power supply of modern society.
