[0003] However, when the existing insulation heat shrinkable sleeve on the combined copper bar is put into the tunnel furnace for heat shrinkage forming, the combined copper bar is usually directly placed on the conveyor belt, so that the bottom of the heat shrinkable sleeve on the copper bar is directly attached to the top surface of the conveyor belt, which is easy to interfere with the shrinkage deformation of the heat shrinkable sleeve, and the heat source position in the tunnel furnace is usually in the middle of the top end inside the tunnel furnace, and the position does not change, so that the middle of the heat shrinkable sleeve is more likely to be heated and shrinked first, and the two ends of the heat shrinkable sleeve are not easy to be heat formed, thus being not conducive to the heat shrinkage forming of the heat shrinkable sleeve on the copper bar; in addition, since the main component of the heat shrinkable sleeve is polyvinyl chloride, this material will release substances harmful to the human body when heated, and the current way adopted by the tunnel furnace is forced ventilation, which directly discharges the harmful substances to the outdoor, and long-term discharge is easy to pollute the surrounding atmospheric environment, is not environmentally friendly, and at the same time, heat is also discharged to the outdoor with the harmful substances, which is easy to cause large heat loss, and is not energy-saving.
