Description
技术领域 technical field
本实用新型涉及一种电线电缆，具体说是一种64/110kV交联聚乙烯绝缘高压电力电缆。 The utility model relates to a wire and cable, in particular to a 64/110kV XLPE insulated high-voltage power cable.
背景技术 Background technique
随着社会的发展，城市越来越大，用电负荷越来越高，供电的安全要求越来越重要。城市供电线路越来越密、越来越复杂。同时因城市市容需要，要求尽可能美观，尽量不采用架空线路，尽可能地采用电缆入地。基于以上原因，现在的大中型城市大量采用64/110kV的交联聚乙烯电缆，通过地下来完成大容量电能的输送。 With the development of society, cities are getting bigger and bigger, and the power load is getting higher and higher, so the safety requirements of power supply are becoming more and more important. Urban power supply lines are becoming denser and more complex. At the same time, due to the needs of the city's appearance, it is required to be as beautiful as possible, try not to use overhead lines, and use cables to enter the ground as much as possible. Based on the above reasons, a large number of 64/110kV XLPE cables are used in large and medium-sized cities to complete the transmission of large-capacity electric energy through the ground.
64/110kV电力电缆的结构组成主要有导体、绝缘、防水层及外保护层。64/110kV电力电缆属于高压电力电缆，通电后电缆绝缘中的电场强度较大，任何结构设计不当、制造缺陷、或安装运行不正确，均会造成电缆击穿，无法正常使用；电缆制造过程中，绝缘要保证没有污染，若绝缘中存在杂质或气泡，则电缆通电后很容易击穿；电缆在运行过程中若有水分进入电缆的绝缘，则电缆的寿命会大大降低。 The structural components of 64/110kV power cables mainly include conductors, insulation, waterproof layer and outer protective layer. 64/110kV power cables are high-voltage power cables. After power-on, the electric field strength in the cable insulation is relatively large. Any improper structural design, manufacturing defects, or incorrect installation and operation will cause cable breakdown and cannot be used normally; during the cable manufacturing process , The insulation must be free from pollution. If there are impurities or air bubbles in the insulation, the cable will easily break down after being energized; if the cable has moisture entering the insulation of the cable during operation, the life of the cable will be greatly reduced.

导电导体屏蔽层、交联聚乙烯绝缘层、半导电绝缘屏蔽层三者紧密光滑地结合在一起，这样就保证电缆通电后交联聚乙烯绝缘层中的电缆场不会畸形，分布均匀。采用第一半导电阻水带，它遇水会迅速膨胀，能有效地阻断水分的进入，延长电缆使用寿命。铜扎带是用铜带绕包，用于扎紧铜丝屏蔽层中的铜丝。第二半导电阻水带是用于阻断水分向电缆时渗透。 Conductive conductor shielding layer, XLPE insulation layer and semi-conductive insulation shielding layer are closely and smoothly combined to ensure that the cable field in the XLPE insulation layer will not be deformed and evenly distributed after the cable is energized. The first semi-conductive resistance hose is used, which will expand rapidly when it encounters water, which can effectively block the entry of water and prolong the service life of the cable. Copper cable ties are wrapped with copper tape and used to tie up the copper wires in the copper wire shielding layer. The second semi-conductive resistance hose is used to block the penetration of moisture to the cable.
所述铝塑复合带纵包在第二半导电阻水带的外面；由于铝为性能优良的金属材料，所以水分不会透过铝塑复合带，从而达到防水的效果。 The aluminum-plastic composite tape is longitudinally wrapped on the outside of the second semiconducting resistance hose; since aluminum is a metal material with excellent performance, moisture will not pass through the aluminum-plastic composite tape, thereby achieving a waterproof effect.
