It possesses the excellent oxidative stability and colloidal stability of filling gel to optical fiber loose tube prepared with complex thickener and blended base Stock,it solves the problem of hydrogen-escape,and its properties reach the level of imported sample.

The three formation mechanisms of expansion and shrinkage in aerial fiber optic cable s loose tube and jacket,which are thermal-shrinkage,heating expansion and cooling shrinkage and residual stress are discussed.

Based on the brief introduction of composition and craft process of the loose tube line for mining flameproof cable,PLC used in the electrical control system is mainly introduced,and real-time monitors the production process together with Kingview.
