SEALING GLAND SYSTEM
A sealing gland system having an upper half, a lower half, and a sealing material positioned between the upper and lower halves. Each of the upper and lower halves and the sealing material has at least one opening extending therethrough, and wherein the sealing material forms a seal around at least one cable extending through the sealing material upon compression thereof.
1 . A sealing gland system comprising:
an upper plate;
a lower plate;
a sealing material positioned between the upper and lower plates and having at least one opening extending through the sealing material, and which is configured to receive at least one cable, the sealing material having at least one slit extending from an outer edge to the at least one opening within the sealing material, and wherein the at least one slit extending from the outer edge to the at least one opening within the sealing material is on a slight diagonal from an upper surface to a lower surface of the sealing material; and
a bolt which extends through the upper plate, the sealing material, and the lower plate, and upon tightening compresses the sealing material around the at least one opening extending therethrough.
2 . The system of claim 1 , further comprising an upper split pressure plate and a lower split pressure plate positioned between the upper plate and the sealing material and the lower plate and the sealing material, respectively.
3 . The system of claim 2 , wherein the upper and the lower split pressure plates each have a first half and a second half, which form at least one opening extending through the upper split pressure plate and the lower split pressure plate, and which is configured to receive the at least one cable
4 . The system of claim 3 , wherein the first and the second halves of the upper split pressure plate and the lower split pressure plate have reciprocating grooves and projections such that the first and second halves are aligned with one another.
5 . The system of claim 1 , wherein at least the lower plate has a screw thread for receiving a thread of the bolt.
6 . The system of claim 1 , wherein the at least one opening comprises a first opening and a second opening, which are configured to receive an entry distribution cable and an exit distribution cable, and wherein the bolt is positioned between the first and the second openings.
7 . The system of claim 1 , wherein the sealing material is an elastic hydrocarbon polymeric material, a synthetic material and/or a polymeric material.
8 . The system of claim 1 , wherein the upper plate has at least one cutout, which forms a first slot on an outer edge thereof, and the lower plate has at least one cutout, which forms a second slot on an outer edge thereof.
9 . The system of claim 1 , wherein the at least one cutout, which forms the first and second slots on the outer edge of the upper and the lower plates comprises a pair of cutouts, which forms a pair of slots on the outer edge of each of the upper and lower plates, and wherein the upper split pressure plate and the lower slit pressure plate includes a pair of guide ridges on an outer portion, which extend into the slots within the upper plate and the lower plate.
10 . The system of claim 1 , further comprising a fastener, which attaches to a distal end of the bolt.
11 . The system of claim 1 , wherein the bolt is a threaded bolt.
12 . The system of claim 11 , further comprising a fastener, which attaches to a distal end of the threaded bolt.
13 . The system of claim 1 , wherein the first half and the second half of the upper and the lower pressure plates are not fixed to one another.
14 . The system of claim 1 , wherein the upper plate, the lower plate and the sealing material has an oval shape.
15 . The system of claim 1 , wherein the upper split pressure plate and the lower split pressure plate has an oval shape.
