Use the utility model of technique scheme, the raw material of clinker particles by feeding device enter into heater interior after,
By the electromagnetic heater on screw rod, the material in whole barrel is made to be heated evenly, the most melted, and revolved by screw rod
The dynamic material made after melting of transhipment advances to compression, homogenizing, and stream flows to extruder head, so that it is guaranteed that molding cable quality；
Vacuum extractor makes pipeline communication head afterbody by vacuum pump evacuation, makes clad and cable core be in vacuum shape, is squeezing
Under pressure effect, protective cover material can steady, solid under realize sheath cladding so that it is fit tightr, it is to avoid wrinkling situation
Occur, thus improve cable quality.
Limiting further, described insulation thickness is 4mm.
Limit further, described radiation protective layer be thickness be the metal fiber composite of 2mm.
The thermal insulation layer of 4mm be in order in case in barrel temperature too high, shell can also be protected simultaneously.
Limiting further, the diameter of described first circular hole and the second circular hole is respectively 10mm.
First circular hole of a diameter of 10mm and the second circular hole are present to ensure that cable core can pass through, simultaneously it is also ensured that true
Empty pump operationally, can make the first pipeline form negative pressure, so that cable core is more tight, further with insulating sheath laminating
Improve cable quality.
The most former material of this utility model is heated evenly, sheath is more tight with metal armor layers, product quality height.
