2results about How to "Increase the compression factor" patented technology

The utility model belongs to the technical field of cables, and particularly relates to a hoisting B1-level fireproof cable for constructional engineering, which comprises a plurality of wire cores, an insulating layer is fixedly connected to the outer wall of each wire core, a first fireproof layer is fixedly connected to the outer wall of each insulating layer, a filling layer is fixedly connected to the outer wall of each first fireproof layer, and a second fireproof layer is fixedly connected to the outer wall of each filling layer. A plurality of mounting holes are formed in the filling layer, protective sleeves are fixedly connected to the inner walls of the mounting holes, load-bearing steel ropes are fixedly connected to the interiors of the protective sleeves, a shielding layer is fixedly connected to the outer wall of the filling layer, and a second fireproof layer is fixedly connected to the outer wall of the shielding layer. According to the utility model, through the design of the wire core, the effects that the compression coefficient of the conductor is effectively improved, the outer diameter of the conductor is reduced, the gaps among the wire cores are reduced, and the quality accident that the conductor is oxidized due to the fact that air and water enter the gaps of the conductor are reduced are achieved; through the design, the battery cell has good conductivity.

The utility model discloses a novel conductor three layer co -extrusion mould and novel conductor, novel conductor three layer co -extrusion mould includes mould body and the mould core of detachable setting on mould body, be equipped with conductor export on the mould body, the mould core includes mould core body and the extrusion channel in the middle part of mould core body, the diameter of extrusion channel is slightly greater than the diameter of conductor export, and the inner wall of extrusion channel is coated with the nanometer coating of reducing the friction between conductor and extrusion channel, has reduced the friction between conductor and mould in the production process greatly, has solved the problem of conductor burr and die mouth aluminum powder accumulation because of friction.
