The EW-5 explosion-proof armor stuffing box is designed to ensure good electrical contact between the shielding layer of shielded cables and the equipment housing or electrical cabinet, while considering the electromagnetic interference between different electrical devices. It achieves common grounding while ensuring a good protection level. The EW-5 explosion-proof armor stuffing box utilizes a compound sealing method with clay filling around the cable conductors and provides waterproof and dustproof sealing on the cable sheath, offering mechanical support to the cable. This product is suitable for use in areas at risk of explosion and allows non-armored cables to be directly inserted into explosion-proof enclosures, luminaires, sockets, plugs, etc. Equipped with a sealing ring that extends onto the cable at the entrance, it ensures compliance with "Ex db llCGb; Exeb llC Gb; Extb lllC Db" certification and IP66/68 protection level. As a result, the cable sealing box provides performance, long-term reliability, and safety, compatible with a wide range of commercial primary cables and compliant with applicable regulations.
