Its further technical scheme is:
Described copper wire is wound around to be shielding for and adopts the soft copper silk of annealing to arrange successively in the outside of bag buffer water-blocking band, and adjacent copper wire gap is less than a brass wire diameter;
Described waterstop lap wound of attaching most importance to wraps in outside metal copper strips;
Described packing is Halogen elastomer material;
Described oversheath is irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin material.
The beneficial effects of the utility model are as follows:
The utility model, by increasing water blocking layer, core and cable core designs multilayer flashing structure, reaches the object blocked water; To fill and sheath adopts low cigarette, bittern-free flame-proof material, by special technique, reach fire-retardant, the requirement of Halogen; Shielding adopts Concentric conductor shielded layer, and adopt copper wire winding process, its cross section meets neutral line need of work, can improve overload capacity, can improve shielding action again.
The utility model production technology equipment is simple, adopts existing equipment to get final product processing and manufacturing.
The utility model changes traditional frequency conversion device structure, changes triple line stranding into, Concentric conductor shielded structure, fundamentally improves interference free performance and the overload capacity of cable.
The utility model arranges water blocking layer outside insulated wire cores He after stranding, improves the serviceability of cable in wet environment, meets the requirement blocked water.
