Three-point Grounding Method Under OPGW optical cable

OPGW - OPTICAL GROUND WIRE · OPGW or known as Optical Ground Wire is a type of cable or wire that is used in transmission lines construction. FIBERFUTURE as a professional OPGW Cable manufacturer with 19 years industrial experience, we can customize OPGW Cable 2-144 Core.

Today we will share 3 types of grounding methods for OPGW optical cables:

1.  
2. Three-point grounding method for cement pole OPGW optical cable

1) The upper end of the door frame is connected with steel-core aluminum stranded wire, one end is connected to the OPGW optical cable with a parallel groove clamp, and the other end is crimped with an aluminum nose and then connected to the grounding body with metal bolts.

2) Connect the steel core pin stranded wire in front of the remaining cable rack. One end is connected to the OPGW optical cable with a parallel groove clamp, and the other end is connected and fixed with the grounding flat steel strip using steel clamps and metal bolts.

3) Use steel or aluminum stranded wires to connect the remaining cable rack and the splice box. One end is connected to the OPGW optical cable using a parallel groove clamp, and the other end is connected to the grounding flat steel strip using steel clamps and metal bolts. Tongding.

2. Three-point grounding method for steel pipe skewed OPGW optical cable

1) The upper end of the door frame is connected with steel-core aluminum stranded wire, one end is connected to the OPGW optical cable with a parallel groove clamp, and the other end is crimped with an aluminum nose and then connected to the grounding body with metal bolts.

2) Use steel-core aluminum stranded wires to connect in front of the remaining cable rack. One end of the strand is connected to the OPGW optical cable with a parallel groove clamp, and the other end is connected to the ground connection of the steel-core aluminum conductor with a parallel groove clamp.

3. Three-point grounding method for tower OPGW optical cable

1). The upper end of the door frame is connected with steel core aluminum stranded wire. One end of the cable clamp is connected to the OPGW optical cable, and the other end is crimped with an aluminum nose and then connected to the ground body with metal bolts.

2) Use steel-aluminum stranded wire to connect in front of the remaining cable rack, and use a parallel groove clamp to connect the I1 end to the OPGW optical cable. The aluminum nose at the other end is crimped and then connected to the tower with metal bolts.

3) Use steel-aluminum stranded wire to connect the remaining cable rack and the splice box. One end is connected to the OPGW optical cable with a parallel groove clamp, and the other end is crimped with an aluminum nose and then connected to the tower with metal bolts.
