NAVBF

Barrier cable gland for non-armoured cables with a female threaded entry

The NAVBF series barrier cable glands for non-armored cable, with a female threaded outlet fitting, are designed to guarantee the IP66/67 protection and the explosion protection ‘Ex db IIC; Ex eb IIC ’in applications where installation requirements are needed in accordance with the EN - IEC 60079-14: 2015 standard. The barrier is shaped around the conductors thanks to the particular mixture that flows through them in the special bushing ensuring a complete seal. The liquid resin used prevents the formation of air pockets or voids between the conductors and the bushing (typical problems found with malleable resins). 

  • Resin kit available separately.
