Slip rings pass the electricity by rub between the brushes and rings, so it is not possible to prevent the spark in theory.Normal slip ring only pays attention to its electric property, but less to protection. So it is very dangerous to use normal slip rings in the condition which is easy to explode. Victory-way knows this, and we know the philosophy of the explosion and its protective measures.We design the explosion-proof conductive slip ring, which can be used in explosive gas atmospheres and explosive dust environment, with protection class IP66.
The slip rings passed EX test and got the certificate of conformity from CNEX (Nanyang), the Cer. No. : CNEx12.2698X. Marking: EX d IIC T6 Gb,DIP A21 Ta,T6.
