Release time:

2023-07-26

Cable pipe blocker is mainly used for blocking the import and export of both ends of the cable pipe as a kind of blocking and sealing product. The use of cable pipe blocker to seal the cable pipe mouth, can effectively eliminate rain, sediment, insects and rodents, as well as the circulation of harmful gases in the pipeline, to improve the operational safety coefficient of the cable through the pipe. Due to the differences in the use of the environment, the requirements of the cable pipe blocker are different, so the construction unit should be based on the actual situation to choose different specifications of the performance of the cable blocker.

　　Cable BlockerIt is a kind of blocking and sealing product mainly used for blocking the import and export of cable ducts at both ends. The use of cable pipe blocker for cable pipe mouth sealing, can effectively eliminate rain, sediment, insects and rodents, and harmful gases in the pipeline circulation, improve the operation of the cable through the pipe safety coefficient. Due to the differences in the use of the environment, the requirements of the cable pipe blocker are different, so the construction unit should be based on the actual situation to choose different specifications of the performance of the cable blocker.

　　The main roles of cable blocker are.

　　1. Waterproof blocking - the use of cable blockers at both ends of the cable or through the wall, can prevent rainwater from penetrating into the cable.

　　2. Fire blocking - The use of special flame retardant materials made of cable blockers can prevent the spread of flame through the cable gap.

　　3. Anti-drip - For oil-immersed cables, etc., the use of blockers can prevent oil from leaking through the cable ports.

　　4. Dust and corrosion prevention - Sealing cable ports can prevent dust and corrosive gases from entering the cable.

　　5. Protect joints - The use of blockers at cable joints can provide mechanical protection to avoid damage to the joints.

　　6. Aesthetics and cleanliness - The use of blockers on exposed cable ends can make the cable layout more aesthetically pleasing and clean.

　　7. Labeling - Plugs can be labeled to identify different cables.

　　8. Laying assistance - Some cable blockers have built-in pull cords, which can help to fix the cable laying.

　　To sum up, cable blockers realize various protection and auxiliary functions by blocking the end of cables.
