The three conductor cores are firstly formed into a cable core group protected by the inner sheath, then the cable core group forms a cable whole, the cable whole is protected by the outer sheath, and the inner sheath and the outer sheath are both made of low-smoke halogen-free materials, so that fire prevention and flame retardance are realized.
The utility model relates to a high flexible data cable's of fire prevention further improves part and lies in, links to each other by flexonics spare between the adjacent cable core group. The equal interval between the core group of assurance cable is guaranteed simultaneously to separate between the core group of assurance cable and is set up to the continuation between cable and the cable connects.
The utility model relates to a high flexible data cable's of fire prevention further improves part and lies in, be provided with the metal armor between flame retardant coating and the oversheath. The setting of metal armor layer can guarantee the intensity hardness of cable outer peripheral face, makes its difficult fracture, and the relative bending of cable is not influenced in the setting of metal armor layer simultaneously.
The utility model relates to a high flexible data cable's of fire prevention further improves part and lies in, inner sheath, oversheath are by the preparation of low smoke and zero halogen material. The inner sheath made of the flame-retardant material is sleeved with the outer sheath, so that the overall fire prevention and flame retardance of the cable are ensured.
The utility model relates to a high flexible data cable's of fire prevention further improves part lies in, the spacer sleeve with be provided with waterproof grease layer between the flame retardant coating.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses divide earlier the conductor core to establish and form a plurality of subgroups, protect by the inner sheath, constitute the cable by a plurality of subgroups again wholly, the cable is whole to be protected by the oversheath, realizes the partition and the fire-retardant protection to the multicore cable, and it is long when guaranteeing the use of cable, simultaneously, the conductor core of grouping setting also can make things convenient for continuation between cable and the cable to connect.
2. The utility model discloses a cable core group has the connecting piece to link to each other between, realizes that the interval between the cable core group equals, and the filling of filiform aramid fiber realizes the relatively fixed of cable core group, guarantees the holistic stability of cable.
