110kV Oil-immersed Power Transformers
Customized one-stop solution for transformers
The 110kV oil-immersed power transformer is adapted for 110kV substations, industrial parks, and new energy
power generation, and is designed for the efficient operation of the power system. High-permeability grain-
oriented silicon steel sheets are stacked in multiple steps to form a three / five-limb iron core, which is matched
with pie-type spiral windings to optimize the magnetic circuit and electromagnetic balance, resulting in lower
no-load and load losses; Full-sealed vacuum oil filling combined with nitrogen buffering, and the bell-type oil
tank is equipped with an intelligent breathing oil conservator, which more prominently delays insulation aging
and ensures long-term operation. It meets the highest energy efficiency, has strong impact resistance after
short-circuit tests, and integrates an on-load tap-changer to adapt to power grid fluctuations. The adaptability
to complex scenarios and local energy efficiency optimization (such as adaptation on the new energy power
generation side) are better. The insulation, noise, and protection reach the industry-leading level, focusing on
the efficient and reliable operation of regional power grids and new energy access.
Product Introduction
The 110kV oil-immersed Power Transformer is suitable for 110kV substations, industrial parks and new energy power generation, and is designed for the efficient operation of power systems. It adopts high-permeability grain-oriented silicon steel sheets stacked in multi-level steps to form a three / five-column iron core, combined with disc-type spiral windings, which optimizes the magnetic circuit and electromagnetic balance, resulting in lower no-load and load losses. The fully sealed vacuum oil injection combined with nitrogen buffering, and the bell-jar type oil tank equipped with an intelligent breathing oil storage cabinet, have a more prominent effect in delaying insulation aging, ensuring long-term operation. It meets the highest energy efficiency standards, has strong impact resistance through short-circuit tests, and integrates an on-load tap-changer to adapt to power grid fluctuations. It has better adaptability to complex scenarios and optimized local energy efficiency (such as adaptation to the new energy generation side). Its insulation, noise control and protection performance reach the industry-leading level, focusing on the efficient and reliable operation of regional power grids and new energy access.
