Features
• Single wire central reinforcement core
• Loose tube filled with special waterproof compound
• Complete core filling
• Plastic coated aluminum tape (APL) moisture barrier
• Double-sided plastic-coated steel tape (PSP) improves the moisture resistance of the cable
• Good water-blocking material to prevent water seepage in the longitudinal direction of the cable
- have very good mechanical properties and temperature characteristics
- Single thin round steel wire armor makes the optical cable have stronger tensile properties
- The loose tube material itself has good hydrolysis resistance and high strength
- The tube is filled with special ointment for critical protection of the optical fiber
- Good compression resistance and softness
- Take the following measures to ensure the waterproof performance of the optical cable:
