• The efficacy and type of insulation material in high voltage DC cable

  There are insulating materials everywhere in our lives. It gives us more powerful security. What kind of role does this material play in high-voltage DC cables? Which material is more suitable for high-voltage DC? In the cable, the following NMN insulation paper is edited for you.
  
  From the cable layout point of view, the cable itself is equivalent to a relatively large capacitor, although its conductor core has been grounded, but because there is no effective discharge, a large amount of DC power will still exist in the cable. , causing a series of effects on the cable.
  
  Since the space charge in the high-voltage DC cable is not lost due to the consumption of the medium like the exchange of the power cable, it will accumulate in the non-rounding, laying the bending section, and insulating the defect, so that the electric field strength is much higher than the rating of the cable. The DC voltage and insulation withstand the pulse voltage, which causes the high voltage DC cable to breakdown.
  
  In order to protect the high-voltage DC cable from being broken down, it is necessary to use insulating materials, but it has been proved by experiments that some of the defects of the oil-impregnated paper insulation material are not very suitable for high-voltage DC cables, so it is recommended to choose polyethylene insulation material, which can The cable provides good and effective protection.
  
  In fact, not only high-voltage DC cables, but also other cables and live devices need to be protected by insulating materials. However, the insulation materials selected must be matched with the device in order to achieve the desired insulation performance.
  
  The above is about the efficacy and type of insulation materials in high-voltage DC cables, I believe you must have a lot of gains, I hope the above can help you better use insulation materials.
