Method for producing high homogeneity crosslinkable polyethylene characterized by comprising the following process steps; i. carrying out contamination examination of the polyethylene produced in the tubular reactor in on-line contamination control unit that is an automatic, closed and dust proof system, transmitting the product, of which contamination quantity is maximum 5-10 number of contaminants/kg and contaminants having maximum 150 μm particle size and thereunder, through one way of 2 (two)-way flow system into contaminant separating unit and discharging the product, of which contamination examination is resulted negatively, through another way of 2 (two)-way automatic flow system out of the process, ii. separating contaminants occurred in the course of carrying polyethylene in contaminant separating unit, iii. conveying polyethylene granulars cleaned from its contaminants in homogenization and absorption unit by means of a system with eternal member moving in a perpendicular direction, iv. conditioning polyethylene granulars in the homogenization and absorption unit at 40 - 60 °C for 4-6 hours so as to allow and facilitate to absorb antioxidant- dicumyl liquid mixture (A+B) into polyethylene in the granular form, v. applying sintered filtering on the antioxidant- dicumyl peroxide liquid mixture (A+B) prepared to convert polyethylene granulars into crosslinkable structure under 4-6 bar of pressure, vi. dosing homogeneously the sintered filtered antioxidant- dicumyl peroxide liquid mixture (A+B) by ejecting antioxidant-dicumyl peroxide liquid mixture (A+B) produced by using 1-3 percent of antioxidant by weight and 0,1-0,5 percent of dicumyl peroxide by weight under 2,5-5 bar of air pressure by means of an atomizer that exists in the homogenization and absorption unit and is distributed evenly on the polyethylene granulars of which conditioning is carried out, vii. completing homogenization by means of carrying and distributing polyethylene granulars charged in the homogenization and absorption unit in a perpendicular direction through the cycle, viii. absorbing the antioxidant- dicumyl peroxide liquid mixture (A+B) being in the polyethylene-antioxidant - dicumyl peroxide composition into polyethylene in the result of homogenization, obtaining a crosslinkable polyethylene at 40-60 °C under 1,5-2,0 bar for 18-22 hours so as to cause polyethylene to gain a crosslinkable structure. i. carrying out contamination examination of the polyethylene produced in the tubular reactor in on-line contamination control unit that is an automatic, closed and dust proof system, transmitting the product, of which contamination quantity is maximum 5-10 number of contaminants/kg and contaminants having maximum 150 μm particle size and thereunder, through one way of 2 (two)-way flow system into contaminant separating unit and discharging the product, of which contamination examination is resulted negatively, through another way of 2 (two)-way automatic flow system out of the process, ii. separating contaminants occurred in the course of carrying polyethylene in contaminant separating unit, iii. conveying polyethylene granulars cleaned from its contaminants in homogenization and absorption unit by means of a system with eternal member moving in a perpendicular direction, iv. conditioning polyethylene granulars in the homogenization and absorption unit at 40 - 60 °C for 4-6 hours so as to allow and facilitate to absorb antioxidant- dicumyl liquid mixture (A+B) into polyethylene in the granular form, v. applying sintered filtering on the antioxidant- dicumyl peroxide liquid mixture (A+B) prepared to convert polyethylene granulars into crosslinkable structure under 4-6 bar of pressure, vi. dosing homogeneously the sintered filtered antioxidant- dicumyl peroxide liquid mixture (A+B) by ejecting antioxidant-dicumyl peroxide liquid mixture (A+B) produced by using 1-3 percent of antioxidant by weight and 0,1-0,5 percent of dicumyl peroxide by weight under 2,5-5 bar of air pressure by means of an atomizer that exists in the homogenization and absorption unit and is distributed evenly on the polyethylene granulars of which conditioning is carried out, vii. completing homogenization by means of carrying and distributing polyethylene granulars charged in the homogenization and absorption unit in a perpendicular direction through the cycle, viii. absorbing the antioxidant- dicumyl peroxide liquid mixture (A+B) being in the polyethylene-antioxidant - dicumyl peroxide composition into polyethylene in the result of homogenization, obtaining a crosslinkable polyethylene at 40-60 °C under 1,5-2,0 bar for 18-22 hours so as to cause polyethylene to gain a crosslinkable structure.
