When cable lines pass through different hazardous areas, the use of cable explosion-proof sealing isolation devices can effectively prevent flammable gases, water, fire, etc., from spreading along the cable tray to the distribution room, avoiding equipment damage and power outage accidents. The cable explosion-proof sealing isolation device is an advanced technology application, independently developed detachable product that provides good sealing and protection for cables. This device is safe, lightweight, aesthetically pleasing, and easy to install. By flexibly configuring different modules and combining multiple frames, the application range and scale can be greatly expanded. The advantage lies in the ability to freely replace internal modules as needed without the need for redesigning or selecting cable penetration paths. The equipment can be quickly assembled and is easy to maintain.
