Introduction of S9 Oil Immersed Transformer
Introducing our S9 series oil-immersed transformers, ranging from 50 kVA to 2500 kVA in rated power. These transformers are designed with a focus on enhancing product features, quality, and reliability. The S9 series incorporates new components, materials, and structures to improve electrical strength, mechanical performance, and heat dissipation capabilities. With options for Vector Group configurations of Yyn0 or Dyn11, these transformers provide efficient and reliable power distribution solutions for various industrial and commercial applications.
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.
