Before Xiaobian told you about some of the relevant contents of the fiber optic cable splitter box, today's Xiaobian to tell you about the grounding device structure of the fiber optic cable splitter box, let's take a look.
1. There must be an obvious grounding mark at the protective ground.
2. The grounding device is connected with the metal reinforcing core and the metal moisture barrier layer and the armor layer in the optical cable. The cross-sectional area of the grounding wire must be not less than 6mm2.
3. Withstand voltage level: The withstand voltage between the grounding device and the cabinet and the frame is not less than 3000V (DC), no breakdown and no arcing for 1min.
4. Insulation resistance: The insulation resistance between the grounding device and the gold workpiece of the box must be not less than 2×10^4MΩ, and the test voltage is 500V DC.
