Product Overview
Compared to the S13 series, this oil-Immersed transformer reduces core and copper losses, making it more energy-efficient. It operates with a noise level of ≤45dB(A), meeting the JB/T 10088 noise standard. The transformer also passed the GB 1094.5-2008 test, with a short-circuit withstand capacity of 150% and an oil temperature rise of ≤50K. It is suitable for a wide range of applications, including industrial enterprises, commercial buildings, infrastructure, and power grid systems.
Type And Meaning
Product Features
Maintenance-free
The oil-immersed transformer is fully sealed, keeping the internal components isolated from external air, eliminating the need for core inspections or maintenance during normal operation.
Fully sealed oil tank
This transformer features a fully sealed oil tank that effectively prevents moisture and airborne impurities from entering, ensuring the transformer oil remains clean and uncontaminated.
Strong overload capacit
The short-circuit current tolerance of this transformer reaches 150%, and it can withstand short-term current shocks without being damaged.
