Ex-proof Slip Ring

Details

Explosion-proof slip rings (flameproof type) are intrinsically safe slip ring systemsspecifically engineered for deployment in hazardous atmospheres with flammablegases, explosive dust, or coal mining applications, ensuring compliance with strictsafety standards.


The BJ-30 series explosion-proof slip ring is a fully CNEX and ATEX- certified slip ring system, marking it as China's first domestically manufactured explosion-proofslip ring to achieve ATEX certification. This product complies with EU explosion-proof standards


The BJ-30 series is a custom-engineered solution. For detailed technical parameters, please reach out to TK Engineering.
