3) 由C581引出10路10kV线路,分别为A507的四台变压器,B551的两台变压器,B553TDA装置氢气压缩机2台,C521盐酸装置氯气压缩机1台,盐酸压缩机1台提供电源。其中,变压器回路采用10kV截面为185mm2的三芯铠装电缆,马达回路采用10kV截面为95mm2的三芯铠装电缆。以上电缆线路均沿规划路径埋地敷设。10 10kV lines led from C581 are used to supply power to A507's four transformers, B551 two transformers, B553TDA 2 sets of hydrogen compressor unit, C521 hydrochloric acid chlorine gas compressor unit, and hydrochloric acid compressor unit respectively. Among them, transformer circuit uses x 3-core armored cable with 10kV cross-section 185mm2, motor circuit uses three-core armored cable with 10kV cross-section 95mm2. All cable lines will be laid underground along the planning path.
