Product Description

1. Environmental protective material; compliant with RoHS. 2. The material for the closure is developed by famous suppliers from abroad, excellent performance and could meet all requirements in IEC***3.1 after test. 3. As the material for sealing gasket and closure are unique, our closures could be used repeatedly and low consumption to environment and resource. 4. The fixing device for reinforced core is of high resistant to high voltage and could stand up to *5KV. 5. Non-losable bolts are used to seal the closure so that they won't fall off during field installation. 6. Unique grounding device to ensure the sealing performance, and at the same time easy and convenient for installation. 7. The splice holder could be used for both ribbon and single core fibers. 8. The "vulcanized rubber" sealing device and sealing gasket developed for dome type of FOSC has obtained patent. □ TECHNICAL INDEXES Environmental temperature：**0℃～**5℃ Optical performance： no obvious additional attenuation Temperature recycle：When the closure is pressurized to（*0±5）KPa，*0 times, the drop of air pressure should be less than 5 KPa，no air bubble after *5 minutes when placed under water. Seal performance：when the closure is pressurized up to **0KPa，no air bubble after *5 minutes under water, or no change of air meter after *4 hours. Re-entry performance：the sealing performance could still meet the standard after three times of re-entry. Insulation resistance：≥2×**4MΩ. Voltage resistance：no arc-over or no puncture under *5KVDC/1min.
