Henan Heshan Electric Co., Ltd. manufactures 11KV three-phase oil-immersed transformers, which are crafted with superior technology and rigorous design to meet the high-efficiency, stable, and long-life operation requirements of power distribution networks.
We integrate core material advantages, innovative structural design, and advanced manufacturing processes to provide you with reliable power conversion solutions.
High-performance core: Constructed from high-permeability grain-oriented cold-rolled silicon steel sheets, the core features a multi-stage circular cross-section structure with fully skewed joints. This design minimizes no-load losses and operating noise, ensuring the transformer's high efficiency and quiet operation.
Robust Coil Structure: Both high and low voltage coils adopt a concentric structure, utilizing corrugated oil channels and undergoing impregnation, curing, and secure binding processes, resulting in high mechanical strength and strong short-circuit withstand capability. The high-voltage coil is equipped with taps, allowing voltage adjustment via a tap switch mounted on the box cover (power must be disconnected before operation), flexibly adapting to changes in grid voltage.
Product feature
● High efficiency and energy saving: High-quality iron core and low-loss design effectively reduce operating costs.
● Safe and stable: Robust coil structure and advanced insulation design ensure stable operation of the equipment under complex working conditions.
● Maintenance-free design: Fully sealed corrugated oil tank eliminates the need for regular oil replenishment, reducing maintenance workload and costs.
● Long service life: Vacuum oil filling process and fully sealed structure delay insulation aging, significantly extending equipment life.
● Environmentally friendly and low noise: Low operating noise, no risk of leakage, environmentally friendly.
This product is widely used in 10KV power distribution systems of industrial and mining enterprises, commercial buildings, residential communities, infrastructure, and new energy power generation projects, serving as a core device for power distribution and voltage conversion.
Heshan Electric is committed to ensuring that every transformer is of superior quality from the moment it leaves the factory through sophisticated manufacturing technology and strict quality control. Choosing our 11KV three-phase oil-immersed transformer means choosing a long-lasting and reliable power guarantee.
