Description
Известны двухпроводные нлавающне кабели с концентрически расположеннымн пр мо и обратной токоведущими жилами, обладаюидпе следующими недостатками: внутренн жила пмеет недостаточный отвод тепла; большой диаметр и вес кабел из-за наличи концентричной изол ции жилами; трудность ремонта в услови х эксплуатации .Known two-wire floating cables with concentrically located direct and reverse current-carrying conductors are known; they have the following disadvantages: the internal core lacks heat dissipation; large diameter and weight of the cable due to the presence of concentric insulation conductors; the difficulty of repair under operating conditions.
В описываемом кабеле эти недостатки устран ютс чередующимс расположением проводников пр мой и обратной жил прп однородном навиве их на плавучий элемент.In the cable described, these disadvantages are eliminated by alternating the location of the forward and reverse conductors of the uniform cable wound them on the floating element.
Такое выполнение обеспечивает равномерный отвод тепла от всех жил кабел , упрощает конструкцию и технологию изготовлени кабел и облегчает доступ к любой из жил кабел при осмотре и ремонте.This embodiment ensures uniform heat removal from all cable cores, simplifies the design and technology of cable manufacture, and facilitates access to any cable core during inspection and repair.
На чертеже изображена схема кабел .The drawing shows a diagram of the cable.
На плавучий элемент 5, изолированный резиновой тканью /, наложен повив проводов 2 и 5 из медной или алюминиевой проволоки.On the floating element 5, insulated with a rubber cloth /, the winding of the wires 2 and 5 of copper or aluminum wire was laid.
Сверху провода 2 н 3 закрываютс слоем 4 прорезиненной ткани НЛП резины.On top of the wire 2 n 3 are covered with a layer 4 of rubberized NLP rubber fabric.
Предмет изобретени Subject invention
Плавающий электрический кабель с центрально расположенным плавучим элементом, отличающийс тем, что, с целью обеспеченп равномерного отвода тепла от токоведущих жил кабел и облегчени доступа к ним при ремонте, пр ма и обратна токоведущпе жилы выполнены в виде нескольких изолированных гибких медных или алюминиевых проводов кажда , навитых поверх плавучего элемента так, что отдельные провода пр мой и обратной жил чередуютс между собой по периметру окружности кабел .A floating electrical cable with a centrally located floating element, characterized in that, in order to ensure uniform heat removal from the conductive wires and to facilitate access to them during repairs, straight and reverse conductor wires are made of several insulated flexible copper or aluminum wires wound over the floating element so that the individual wires of the forward and return veins alternate with each other along the circumference of the cable.
