48 Fibers OPGW Optical Cable Metal Joint Box
Part Number: 023990
An OPGW (Optical Ground Wire) Joint Box also known as a splice box, metal joint box, or approach joint closure is a ruggedized outdoor enclosure installed on high-voltage transmission towers, poles,or substation structures to splice, organize, and protect fiber optic connections.
Product Highlights
- Splicing & Continuity: Joins continuous spans of OPGW cables or transitions overhead OPGW strands to indoor/underground approach/downlead cables that run down to the substation control room.
- Environmental & Mechanical Protection: Shields delicate fiber splices from moisture, high winds, ultraviolet rays, extreme temperature swings (-40°C to +60°C), and severe mechanical stress.
- Bending Radius Control: Internal aluminum or engineering-plastic splice trays store excess slack buffer tubes while maintaining safe minimum bending radii to prevent signal loss.
- Grounding & Safety: Equipped with lightning and fault-current grounding devices to handle high-voltage proximity on overhead ground wire systems.
