Mechanical cable entry Seal/cable entry sealing
A flexible silica gel piece and a reinforced plastic pressure plate at both ends are fixed by fasteners and tightened under pressure to make the outer ring of the beam silica gel piece expand outward and tighten the inner wall of the duct,
 while the inner ring of the flexible silica gel piece contracts and tightens the cable inward, so as to achieve the isolation sealing of the duct inside and outside.
Flexible cable entry seal is an innovative mechanical seal structure that can be used repeatedly to seal and waterproof the cable pipe and cable, and prevent silt, debris and small animals 
from entering the pipe and affecting the safety of power cable.

Features and advantages-----
1. Installation is mechanical operation, fast, simple, safe and reliable;
2. Adopt flame-retardant new material and flexible plugging to protect tube wall and sheath layer and prevent vibration displacement of cable;
3. It has high exclusivity and fire resistance, and can effectively isolate open flames and flood defence.
4. Wide application range. It is suitable for all kinds of ducts, such as PVC duct, glass duct, steel duct, etc.
5. Installation is not affected by environmental weather, and water seepage pipes can also be installed;
6. Reusable with a life span of more than 15 years.
7. In order to avoid high air pressure in the pipeline after plugging, one-way pressure reducing valve is set on the plugging device.

Special---
1. The principle of dilatational expansion can obtain a larger diameter range, extending outward 10-15m and inward 10-15mm, which can adapt to a larger diameter of the internal warp and cable.
2 the product can withstand greater water pressure inside the pipe, the water pressure inside the pipe will push the product pressure block to do the opposite direction movement, thus expanding the sealing ring again, make the product more pressure more tight do not fall off, so that the product has a longer service life.
3. The products are made of composite fire-resistant materials, which can effectively restrain the spread of fire and ensure the safety of electric power operation.
