Described control conductor comprises the second second third insulator controlling copper core and be enclosed within control copper core, multiple tooth fastener comprises fixed band, the tooth be located on fixed band, control conductor is located between the tooth of multiple tooth fastener, and fixed band extruding control conductor, makes control conductor contact with PE inner sheath;
Described fixed band wraps up alkali-free glass strap, polyolefin oversheath outward successively, and polyolefin oversheath table is provided with the thick copper strips of 0.1mm-0.14mm or the thick non-magnetic stainless steel band of 0.1mm-0.14mm.
Further, tooth inside is provided with air column.
Further, tooth surface is circular arc.
The utility model has the advantage of, in order to ensure the electric property that cable is excellent and reduce costs, insulation have employed non-flame-retardant material, and sheath have employed the LSOH anti-flaming material with antiultraviolet.The high-flame retardant fire-insulating layer that a layer thickness is 1 ~ 2mm is devised, to realize the flame retardant rating of the fire-retardant of cable or raising cable between insulation and sheath.
Cable waterproof, generally based on radial waterproof, adopts one deck not seep water or to be difficult to permeable material, is blocked in beyond insulating barrier by hydrone, thus reach the object of protection insulation.Usually aluminium/mould stick integrated sheath can be adopted; Also one deck LLDPE material can be designed separately as watertight composition between insulation and sheath, because LLDPE has good toughness, wear-resisting and lower water penetration.Intumescent waterstop is adopted to be wrapped in the outer surface of insulating barrier, to promote its longitudinal or radial waterproof action.The copper strips that 0.12mm is thick or the thick non-magnetic stainless steel steel band of 0.12mm are used as protection against rodents layer, its successful.
By multiple tooth fastener, control conductor is fixed on power wire core periphery uniformly.
Tooth inside is provided with air column, and air column can accelerate the heat of cable.
Tooth surface is circular arc, improves control conductor and tooth contact area.
