Introduction of S11 Oil Immersed Transformer
S11 series oil immersed transformer offering the choice between the Yyn0 or Dyn11 vector group configurations across a wide power range from 30 kVA to 2500 kVA. These transformers are engineered to deliver exceptional performance, efficiency, and reliability in diverse industrial and commercial settings.
The Yyn0 vector group configuration provides a specific phase shift angle, ensuring precise voltage regulation and stability in power distribution networks. On the other hand, the Dyn11 configuration offers an alternative phase shift angle, catering to varying operational requirements with flexibility and adaptability.
One of the key advantages of our transformers lies in their superior energy efficiency, reducing power losses and operational costs over the long term. With advanced design features and high-quality materials, these transformers are built to withstand demanding operating conditions and deliver consistent performance.
Oil-immersed transformers can be widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms, and oil production platforms. They are especially suitable for use in places with high fire protection requirements and harsh environments such as flammable and explosive materials. They can also be used for power and lighting in residential areas, commercial streets, industrial and mining enterprises, and rural areas.

Zhengzhou KBT Transformer Instrument Co., Ltd. is a specialized production enterprise mainly based on power transformers, which integrates product development,production, sales, service and technology consulting.
This series of current transformers features an epoxy‑resin‑cast, fully enclosed insulation design. They are suitable for use in power systems with a rated frequency of 50 Hz or 60 Hz for electrical energy metering. These transformers eliminate oil contamination and fire hazards, reduce maintenance requirements, and meet the demands of oil‑free operation.
The LZZB current transformer is an epoxy‑resin‑cast, fully enclosed device, primarily intended for power systems with a rated frequency of 50 Hz or 60 Hz and a rated voltage of 35 kV or lower. Its core function is to provide high‑accuracy current signals for energy metering, current measurement, and relay protection. This model features excellent dynamic and thermal stability, high accuracy, and a large capacity.
The LZZBJ9-10A current transformer is primarily designed for indoor power systems with a rated frequency of 50 Hz and a rated voltage of 10 kV or less (with a maximum operating voltage of 12 kV). Its core functions are to accurately measure current and electrical energy in the circuit and to provide reliable signals to relay protection devices. This model is widely used in indoor switchgear—such as center‑mounted switchgear and cubicle switchgear—as well as in complete high‑ and low‑voltage equipment sets.
The LZZB1-35W current transformer is an epoxy‑resin‑cast, fully enclosed device, primarily intended for power systems with a rated frequency of 50 Hz or 60 Hz and a rated voltage of 35 kV or lower. Its core function is to provide high‑accuracy current signals for energy metering, current measurement, and relay protection. This model is specifically designed to interface with equipment such as the ZW‑type 35 kV vacuum circuit breaker, offering superior dynamic and thermal stability, high accuracy, and large capacity.
