求翻译：在日本，并联间隙被称为招弧角，其现已有32种型式和280余个不同规格，可在66～154kV之间各级电压线路上使用。在日本所有的500kV架空送电线路的绝缘子都必须要装设招弧角，招弧角的可靠性高，能够保证多年正常运行而无需维护。甚至在1000kV输电线路的绝缘子串上也都装设了招弧角[4]。是什么意思？

Known as the gap in Japan, parallel strokes arc angle is now 32 kinds of types and more than 280 different specifications, can be used on all voltages between 66 ~ 154kv lines. To be installed in all of Japan's 500kv overhead transmission line insulators must move the arc angle, move the arc angle a
