Problems solved by technology
[0003] When the existing cables are installed, when they are manually dragged, they often cause the problem of being out of hand because they are not easy to hold, which reduces the efficiency of installation, and the existing cables have low flame retardancy and poor use effects. Therefore, we propose a fire-resistant low-smoke halogen-free flame-retardant insulated cable

Embodiment
[0024] Embodiment: During the production of the cable, the outer wall of the wear-resistant sleeve 9 is bonded with stoppers 10 at equal intervals through super glue. Cover the outer wall of the cable so that the connecting block 13 at the end of the connecting rod 12 and the connecting groove 102 on the block 10 move to the same plane, and the ring 11 is rotated to allow the connecting block 13 to be completely inserted into the connecting groove 102, so that the staff can When dragging the cable, the connection limit between the connecting block 13 and the stopper 10 prevents the staff from dropping their hands when moving and dragging through the arc-shaped handle 14, which improves the work efficiency and has a good use effect. The double-layer flame-retardant layer arrangement of the flame-retardant filler layer 6 and the flame-retardant tape 7 makes the cable have good flame-retardant and fire-resistant properties.

The invention discloses a fireproof halogen-free low-smoke flame-retardant insulated cable in the technical field of cables, and the cable is characterized in that a conductor is sleeved with an innerprotection sleeve, the outer wall of the inner protection sleeve is sleeved with an insulating layer, an inner cavity of the inner protection sleeve is provided with a filling strip, the insulating layer is sleeved with a reinforcing layer, and the reinforcing layer is sleeved with a flame-retardant filler layer; the outer side of the flame-retardant belt is sleeved with an outer sheath, the outer side of the outer sheath is sleeved with a wear-resistant sleeve, check blocks are bonded to the outer side wall of the wear-resistant sleeve at equal intervals in the circumferential direction, connecting rods are arranged on one side of the circular ring and perpendicular to the circular ring at equal intervals, the tail ends of the connecting rods are fixedly connected with the connecting blocks, and fixed rods are symmetrically arranged on the side wall of the circular ring. The fire-resistant and flame-retardant mobile power supply has the advantages that the fire-resistant and flame-retardant mobile power supply is convenient for workers to move and drag without slipping out of hands, and has good fire-resistant and flame-retardant properties and a good use effect.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a fire-resistant, halogen-free, low-smoke, flame-retardant insulated cable. Background technique [0002] A cable is usually made of one or more mutually insulated conductors and an outer insulating layer, which transmits power or information from one place to another. Existing cables can be divided into various types according to the performance of the cables. , including flame-retardant cables, fire-resistant cables, etc. [0003] When the existing cables are installed, when they are manually dragged, they often cause the problem of being out of hand because they are not easy to hold, which reduces the efficiency of installation, and the existing cables have low flame retardancy and poor use effects. Therefore, we propose a fire-resistant low-smoke halogen-free flame-retardant insulated cable. Contents of the invention [0004] The object of the present invention is to provi...
