When cabling, the wires must be collected neatly; S5: Internal protection process: replace the filter screen before production, clean the screw, the dividing cone and the flange to ensure that no impurities enter, the inner sheath (4) uses anti-signal interference sheath material, and the outer sheath is longitudinally wrapped with a water-blocking tape (8) and a steel belt armor layer (22). After the production of the internal protection is completed, each coil of internal protection needs to be tested for appearance size, water seepage, attenuation, and composite tape overlap. After passing the test, it will be put into the next process of production; S6: External protection process: replace the filter before production, clean the screw, dividing cone and flange to ensure that no impurities enter. The outer sheath (1) uses anti-signal interference sheath material, and the inner sheath is reinforced with galvanized steel wire mesh (2). After the outer sheath (1) is produced, each finished product needs to be tested for appearance size, water seepage, attenuation, and integrated optical cable printing. After passing the test, it will be packaged and shipped.
