           outdoor preinstalled type substation (American type)



           产品特点 Characteristics of the product

           ◆ 全绝缘、全密封、免少维护、可靠保证人身安全；
           ◆ 结构紧凑、体积仅为同容量欧变的 1/3-1/5，高度低；
           ◆ 可采用分箱式结构，避免变压器油箱内油的污染；
           ◆ 高压侧采用双熔丝全范围保护，大大降低成本；
           ◆ 即可用环网，也可用于终端，电缆头可在 200A 负荷电流时紧急插拔；
           ◆ 箱体采用蜂窝式双夹层复合板，隔温又散热的功能；
           ◆ 低压侧加装电子缺相保护器，当系统内出现不正常电压时，可快速分断主进开关；
           ◆ 高压侧油浸式负荷开关或 SF6 负荷开关，可电动升级，为实现配网自动化打下基础；
           ◆ 采用油浸式 S9 或性能更优的 S11 系列变压器。
           ◆ Fully insulated, fully sealed, less maintenance, reliable guarantee of personal safety;
           ◆ Compact structure, the volume is only with the capacity of the European variable 1 / 3-1 / 5, low height;
           ◆ Can be used sub-box structure, to avoid oil pollution in the transformer tank;
           ◆ High-side fuse with a full range of protection, greatly reducing costs；
           ◆ You can use the ring network can also be used for the terminal, the cable can be 200A load current emergency plug;
           ◆ The cabinet adopts the honeycomb double sandwich composite board, the function of heat insulation and heat dissipation;
           ◆ Low-voltage side of the installation of electronic phase protection, when the system voltage is not normal, you can quickly break the main switch;
           ◆ High-pressure side oil-filled load switch or SF6 load switch can be electrically upgraded to lay the foundation for the realization of distribution
             automation.
           ◆ The use of oil-immersed S9 or better performance of the S11 series transformers.
