Fiber Optic Splice Closure Overview Standard cable junction box is used for outdoor cable junction box wiring, welding and fibre storage at both ends of cable junction box. It is suitable for connection and divergent application in overhead, pipeline manhole, directly buried and pipeline laying cable, and plays the role of joint protection. It has the functions of restoring the integrity of the protective sheath of the optical cable and strengthening the mechanical continuity of the construction of the optical cable; providing electrical connection, grounding or disconnection of the metal components in the optical cable; protecting the optical cable joint from environmental impact; installing the optical fiber joint and storing the excess length of the optical fiber.
Ⅱ. Functional characteristics: 1. The box body is formed by injection moulding of new ABS material. It has good anti-alkali corrosion and anti-aging properties, and its surface is clean and beautiful, its mechanical structure is firm, and it has strong anti-field environment performance. It can withstand severe climate change and harsh working environment. 2. Suitable for ribbon optical cable and ordinary optical cable. The fused disc in the box can be flipped by pages, and there is enough curvature radius and space for each optical cable and each optical fiber to be constructed separately. 3. Small size, large capacity and convenient maintenance. 4. Provide reliable cable fixing and cable reinforcement core grounding protection device.
III. Working conditions: Working temperature: -40 +55. Relative humidity: <95%(+40 C) Atmospheric pressure: 70kPa-106 kPa IV. Technical requirements: 1. Sealing performance: After the box is closed, it is inflated inward to (100 + 5) Pa, and immersed in a clear water container at room temperature for 15 minutes. No bubbles escape. 2. Insulation Resistance: Insulation Resistance between Metal Components and Ground (> 2x104_) 3. Voltage withstanding: No breakdown and no arc between metal components and ground under the action of 15 kV (DC) / 1 min. 4. The radius of curvature of the optical coil is more than or equal to 40 mm, and there is no additional loss in the optical fiber fusion disc. 5. Tensile: Can withstand the axial tension force (> 1000N). 6. Life: More than 25 years.
V. product standard accessories: Optical fiber heat shrinkable tube, 1 roll of insulating tape, 2 pairs of stainless steel screw nuts, 8 nylon straps. Two stainless steel hooks, one inner hexagonal wrench and four positioning rings, big, medium and small, respectively.
