Application

33kV three-phase oil-immersed transformers are widely used in rural power grids, industry, commerce, new energy, public facilities and other fields. They have been verified to have high reliability in more than 50 countries and regions around the world and have been sold to South Africa, Zimbabwe, Sudan, Kenya, Mozambique, Tanzania, Ethiopia, Nigeria, Namibia, Iraq, UAE, Saudi Arabia and other countries and regions.

Advantages

  • Standards: GB, IEC, GOST, EN, NF, ANSI / IEEE (customizable according to customer standards)
  • Certification: ISO, CE, IEC, SA BS, COC, CSA, UL
  • Efficiency: 33kV three-phase oil-immersed transformer efficiency can reach more than 99%
  • Maintenance-free: IP65 protection level, dust and moisture proof, maintenance-free, design life of more than 25 years.
  • Environmental protection and sustainable development: FR3 vegetable oil can be selected.
  • Overload capacity: Copper coil 33kv transformer allows short-term overload to 150% of rated capacity, lasting no more than 2 hours, but requires monitoring of oil temperature (≤95℃).

Type: 33kV three-phase transformer

  • These types of transformers have the same principle, but different structures, and different types of transformers have different applications.
  • 33kV three-phase oil-immersed transformer (rated voltage 6kV-35kV)
  • 33kV pole-mounted three-phase oil-immersed transformer (rated voltage 2.4kv-34.5kv)
  • 33kV three-phase box-type transformer (rated voltage 2.4kV-34.5kV)
