Introduction to 35kV Oil-Immersed Power Transformer

A 35kV oil-immersed power transformer is a type of electrical transformer that utilizes mineral or synthetic oils for insulation and cooling. It is specifically designed to step-down or step-up voltages in power distribution systems, commonly used in utilities and industrial power applications. The transformer operates at a primary voltage level of 35kV.

Characteristics and Specifications

The 35kV oil-immersed power transformers are characterized by their efficacy in high-voltage transmission networks. The following are key parameters:

• Rated Capacity: Typically ranges from 10MVA to 100MVA.
• Cooling Method: Utilizes ONAN (Oil Natural Air Natural) or ONAF (Oil Natural Air Forced).
• Insulation Material: Mineral oil or silicon-based insulating fluids.
• Temperature Rise: Average winding temperature rise limited to 55°C.
• Impedance Voltage: Typically ranges from 6% to 10% for enhanced voltage regulation.

Advantages of Oil-Immersed Transformers

The adoption of 35kV oil-immersed transformers provides numerous advantages:

• High Efficiency: These transformers offer efficiency levels above 98%, minimizing energy losses.
• Improved Cooling: Oil-immersion ensures better heat dissipation compared to dry-type transformers.
• Durability: Extended life spans due to robust construction and cooling methods.
• Fire Protection: Reduced risk of fire hazards as the insulating oil acts as a dielectric medium.
