The utility model relates to the technical field of cable conductors, in particular to an energy-saving consumption-reducing monofilament mixed stranded cable conductor, which comprises a conductor, the conductor comprises a plurality of buckle type special-shaped monofilaments and a plurality of circular monofilaments, the cross section of each circular monofilament is circular, and the buckle type special-shaped monofilaments are interlocked and meshed. The utility model has the following advantages: (1) buckle type special-shaped monofilaments and round monofilaments with specific specifications are produced, the number of filaments is small, the number of times of wire drawing and die changing is small, the production efficiency can reach the round monofilament wire drawing capacity and production efficiency on the premise that two wire drawing machines are matched, the capacity is high, the requirement on equipment is low, and the requirement on the operating skill of workers is not high; and (2) low-oxygen copper and oxygen-free copper are adopted, only the inner-layer circular monofilament needs to be replaced when the resistor richness is too large or too small, the inner-layer circular monofilament is easy to repair, the later-period out-of-period problems are few, the after-sale cost is reduced, and copper material consumption can be saved to the maximum extent.

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.
