Description
Насто щее изобретение относитс к способам изготовлени кабелей и ироводов с пластмассовой изол цией, накладываемой в пластическом состо нии иа токоведущие жилы с последующим ее охлаждением .The present invention relates to methods for the manufacture of cables and wires with plastic insulation applied in the plastic state and the current-carrying cores, followed by its cooling.
Предлагаемый способ отличаетс от известиых тем, что токоведущие жилы подвергают до их оирессовани искусственному охлаладению , а охлаждение изол ции после опрессоваии производ т под давлением выше атмосферного.The proposed method differs from the lime in that the current-carrying conductors are subjected to artificial cooling before heating them, and the cooling of the insulation after crimping is carried out under a pressure higher than atmospheric.
Это позвол ет предотвратить образование газовых включений в накладываемой изол ции.This prevents the formation of gas impurities in the overlapping insulation.
На фиг. 1 изображена схема изготовлени кабел по предлагаемому способу; на фиг. 2-один из вариантов выполнени охлаждающей трубы.FIG. 1 shows a scheme for manufacturing a cable according to the proposed method; in fig. 2 is one embodiment of a cooling tube.
Токоведуща жила, наход ща с на барабане /, помещаетс в контейнер 2 с низкой темпсратлрой, в котором происходит ее охлаждение . Затем в прессе 3 на жилу накладываетс изол ци и кабель или провод направл етс в открытую охлаждающую вод ную ванну 4 и далее в трубу 5, в которой изол ци его охлаждаетс газом или жидкостью, подаваемыми под давлением. Наличие в трубе 5 давлени исключает возможность образовани в накладываемой изол ции пустот от газовых включений. Далее, охлаждаемый кабель проходит через контрольные устройства 6, т говые устройства 7 и поступает на приемник 8.The current-carrying core located on the drum / is placed in a low temperature container 2 in which it is cooled. Then, in the press 3, insulation is applied to the core and the cable or wire is guided into an open cooling water bath 4 and then into pipe 5, in which the insulation is cooled by gas or liquid supplied under pressure. The presence in the pipe 5 of the pressure eliminates the possibility of the formation of voids in the overlaid insulation from gas inclusions. Next, the cooled cable passes through the control device 6, the traction device 7 and enters the receiver 8.
Дл улучшени охлаждени , можно направить поток охлаждающей жидкости или газа навстречу движению кабел и создать в трубе 5 систему порогов 9 (фиг. 2), благодар чему давление в трубе будет возрастать вдоль ее длины, т. е. по мере увеличени толщины охлаждаемого сло изол ции.To improve cooling, you can direct the flow of coolant or gas towards the movement of the cable and create a system of thresholds 9 in the pipe 5 (Fig. 2), whereby the pressure in the pipe will increase along its length, i.e. as the thickness of the insulation layer increases. of
Дл более плавного охлаждени нластмассовой изол ции, может быть нрименен постепенный нагрев воды от выходного конца трубы 5 к ее входному концу с, номощью электронагревателей. Можно также производить нонеременное охлаждение кабел и его нагрев, что будет способетвовать разм гчению верхнего сло изол ции и лучшей его усадки. For smoother cooling of the plastic insulation, it can be applied to gradually heat water from the outlet end of the pipe 5 to its inlet end with the help of electric heaters. It is also possible to perform non-variable cooling of the cable and its heating, which will help soften the upper insulation layer and better shrink it.
