CABLE STUFFING ARRANGEMENT Russian patent published in 1994 - IPC

FIELD: explosion-proof mine electrical equipment. SUBSTANCE: stuffing arrangement has box with as many through insulators as there are cable conductors to be brought in, flexible sealing cup, and barrier made of conducting material and provided with hole 7 and port 8 with dielectric insert 9 provided with holes 10. As cable is pulled out, shortest conductor passing through hole 7 is first to come in contact with bare end of barrier whose height equals depth of box. Barrier is in electric contact with grounded shell of electrical equipment; therefore, when cable is pulled out, supply voltage is cut off thereby preventing explosion, fire, and electric shock. EFFECT: improved safety of device. 6 dwg
