HUARUI 
35KV Oil Transformer
The 35kV oil-immersed transformer is a power device that uses insulating oil as both insulation and cooling medium, and is designed to change voltage levels for the transmission of AC electrical energy within a 35kV distribution and sub-transmission system. This product is primarily applied in 35kV power networks for step-up or step-down voltage conversion. It features compact layout, reliable mechanical structure, stable performance and strong environmental adaptability. As key sub-transmission equipment, it connects high-voltage transmission network with medium-voltage distribution network, widely adopted for urban and rural power grids, industrial parks, mining enterprises, new energy power stations and municipal infrastructure projects. It delivers high operating efficiency and excellent short-circuit withstand capability to guarantee safe and continuous power supply for downstream loads.

The equipment is generally suitable for installation at altitudes not exceeding 1,000 m, ambient temperatures ranging from -30 °C to +45 °C, average daily relative humidity not greater than 95%, outdoor wind speed not exceeding 35 m/s, and seismic intensity not exceeding VIII degree. For special environments such as high altitude, high temperature, high humidity, or salt spray, special insulation and temperature rise correction designs are required, or alternative modification solutions shall be negotiated. It is widely deployed for regional substations, industrial-mining enterprises, large industrial parks, photovoltaic and wind power booster stations, urban-rural sub-transmission networks and key municipal power supply projects.
