Product Overview
Chinese box type transformer substation is different from American box type transformer substation and European box type transformer substation. The unique R method high-voltage connection, which is the first in the industry, has China’s independent intellectual property rights, and fully demonstrates the extraordinary features of the Chinese box type transformer: safety, reliability, convenience, and environmental protection. At present, it has been widely used in 35KV power transformation and distribution fields such as photovoltaic and wind power.
Product Highlights
1.No oil draining or refilling required, eliminating maintenance troubles of American-type box substations.
2.System operation keeps running without power outage, power generation remains unaffected.
3.The transformer is shielded from direct sunlight to achieve higher generating efficiency.
4.Insulating oil stays free from contamination, securing stable performance for 20 years.
5.Safe, convenient operation & maintenance, adaptable to harsh weather conditions.
6.Full thermal insulation protection, with natural ventilation for heat dissipation.
