Description
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 *5 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 ****5m and inward ****5mm, 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.
