Description
Предлагаемый согласноизобретению способ изготовлени электрических кабелей с изол цией из бумажной массы заключаетс в следующем. Целлюлоза, бумажна масса или смесь того и другого загружаетс в сушильно-пропиточный котел, в котором она подвергаетс сушке. По истечении установленного времени в котел подаетс кака -либо из обычно примен емых в кабельном производстве пропитывающих масс, и производитс пропитка высушенной целлюлозы . Затем размельченна и превращенна в кашеобразное состо ние пропитанна масса подаетс по трубам к месту, где производитс процесс изолировани .The method for manufacturing electrical cables with paper stock insulation as proposed in accordance with the invention is as follows. Pulp, paper pulp, or a mixture of both, is loaded into a drying and impregnating boiler in which it is dried. After the set time has elapsed, some of the impregnating masses commonly used in cable production are fed into the boiler, and the dried pulp is impregnated. Then the crushed and caked impregnated mass is piped to the place where the isolation process is performed.
Процесс изолировани производитс на щприц-прессе, по конструкций, аналогичной прессам, примен ющимс при изготовлении проводов с резиновой изол цией . До наложени на жилу, масса подвергаетс охлаждению и при температуре , при которой достигаетс необходима консистенци , достаточна дл удовлетворительного процесса опрессовки , производитс опрессование.The isolation process is performed on a press syringe, in designs similar to the presses used in the manufacture of rubber insulated wires. Before overlaying the core, the mass is subjected to cooling and at a temperature at which the necessary consistency is reached, sufficient for a satisfactory crimping process, pressure testing is performed.
Росле опрессовки производитс обмотка кабел редкой миткалевой лентой или соответствующим материалом дл The wire is crimped using rare metal tape or an appropriate material for

укреплени массы на жиле. Затем производитс разогрев массы на кабеле и выжимание избыточного компаунда, дл чего на пути следовани кабел устанавливаетс нагревающа труба. По выходе из трубы, жидкий избыточный компаунд выжимаетс способом вторичной тугой намотки миткал или соответствующего материала на кабель. Дл разогрева кабел на ходу может быть применен высокочастотный генератор, разогревающий кабель за счет диэлектрических потерь в изолирующего сло или за счет токов Фуко в самой жиле. Наложение защитных покровов производитс затем обычным пор дком как и на другие кабели.strengthening the mass on the vein. Then, the cable mass is heated and the excess compound is squeezed out, for which a heating tube is installed along the cable path. Upon exiting the pipe, the liquid excess compound is squeezed by the method of secondary tight winding of a mical or an appropriate material on the cable. To heat the cable on the move, a high-frequency generator can be used, heating the cable due to dielectric losses in the insulating layer or due to Foucault currents in the core itself. The protective cover is then applied in the usual order, like on other cables.
