Wherein, the cable core filled layer is high-intensitive aramid yarn, which has high tensile, softness, resistance to ag(e)ing It is excellent, it ensure that the service life of cable entirety.

Wherein, the outer lapping layer attach most importance to lap wound packet non-woven fabrics constitute.

Compared with prior art, the utility model has the following beneficial effects:

1. cable core conductor is closed using the 5th kind of tin plating soft copper conductor and steel wire strengthening core beam and constituted, cooperate steel wire strengthening core, The tensile strength of cable is substantially increased, while ensuring that cable keeps excellent electric property in the process of running, and pliable Circumnutate around, pull, long service life.

2. using have mechanical performance height, high-tensile, high-flexibility, and with fabulous cold resistance butyronitrile PVC, Insulating layer, sheath is respectively prepared in TPE elastomer, so that cable has high-tensile, cold-resistant, high-flexibility, high winding, height resistance to The characteristics such as mill, the ageing-resistant, weather of resistance to external environment fully meet severe cold area and frequently move requirement with bend tension.

Three flexible steel cables are placed when 3. sheath extruding in the utility model, it is whole that flexible steel cable can effectively increase cable The tensile property of body, while ensuring that cable has stronger tensile property in bending or when by larger external force, it is effectively protected The integrality of cable built-in electrical insulation core, greatly improves the service life of cable.
