Transformer Gas Relay Models

QJ Series

• QJ1-25,QJ1-50,QJ1-80QJ1-25 is suitable for transformers with different capacities, such as QJ1-25 is suitable for transformers with 25MVA and below, QJ1-50 is suitable for transformers with 50MVA and below, and QJ1-80 is suitable for transformers with 80MVA and below.
• QJ2-40: Mainly used to protect all types of oil-immersed, fully sealed transformers.
• QJ4-50,QJ4-80: It is suitable for transformers of larger capacity, such as QJ4-50 for transformers of 50MVA and below, and QJ4-80 for transformers of 80MVA and below.
• QJ-50,QJ-80: For transformers of 50 MVA and below and 80 MVA and below.

EMB Series

• BC-80: Suitable for many types of transformers with high reliability and stability.
• BF-80/10,BF-80/Q: For transformers of different capacities and requirements.

TR Series

• TR-80/TR-80R: For oil-immersed transformers, it can monitor in real time the accumulation of gases inside the transformer due to leakage current, arcing, flashover and other faults.
• TR-25-R-S: Intelligent gas relay, in addition to the basic functions of a traditional gas relay, adds the function of real-time monitoring of the concentration of monohydrogen gas inside the gas relay.

Other Models

• QJM-40: Gas relays for hermetically sealed transformers.
• QYJ-40: Multi-function gas relay with integrated transformer relay,oil level meter,pressure relief valveand other features.
