Insulating tape and shielding tape production system for molded high-voltage cable flexible joint
The preparation method of the wrap-around molded flexible joint is complementary to the extrusion molding method. It is very effective for the preparation of the high-voltage cable flexible joint. Especially when the fault is repaired, the wrap-around molding method is more convenient and effective. In addition, foreign reports indicate that all cable joints below 138kV tend to use wrap-around molding technology, which is more meaningful for domestic system applications below 110kV.The insulation and shielding layer wrapping tape production system are developed based on the integrated technology of polymer material extrusion, casting and slitting, equipped with a real-time detection system for impurities in the insulation tape with electronic cameras.
Insulation tape production system composition: defect-free single screw extruder, casting and slitting machine, film casting die, electronic camera impurity inspection, dual-channel independent mold temperature machine.
