Для жесткого крепления кабеля по 1-му варианту изоляционные элементы дополнительно фиксируются прутками из высокопрочного полимерного материала. Прутки располагаются на верхней опорной поверхности изоляционных элементов, параллельно основанию, и перпендикулярно направлению укладки кабеля, прутки прижаты к верхней опорной поверхности пластиной с профильными концевыми выемками. Прутки изготовлены из высокопрочного полимерного материала для того, чтобы не было замкнутых металлических контуров из магнитных материалов вокруг кабеля.For rigid cable fastening according to the 1st embodiment, the insulating elements are additionally fixed with rods of high-strength polymer material. The rods are located on the upper supporting surface of the insulating elements, parallel to the base, and perpendicular to the direction of cable laying, the rods are pressed against the upper supporting surface by a plate with profile end recesses. The rods are made of high-strength polymer material so that there are no closed metal loops of magnetic materials around the cable.
2-й вариант устройства для крепления кабеля характеризуется тем, что три и более изоляционных элементов зафиксированы фиксирующим элементом U-образной формы, который крепится на основании.The 2nd version of the cable fastening device is characterized in that three or more insulating elements are fixed with a U-shaped fixing element that is mounted on the base.
Устройство для крепления кабеля по 2-му варианту содержит основание 1 (фиг. 1), которое может быть выполнено, например, в виде профиля с перфорацией и подвижно закрепленные вдоль его продольной оси изоляционные элементы 2 (фиг.l). Между двумя изоляционными элементами, установленными на основании, фиксируют два параллельно расположенных кабеля. Третий кабель, который является вершиной «тpeyгoльникa» расположен на основании, образованном кабелями параллельно расположенными. Кабель вершины «тpeyгoльникa» фиксируется изоляционным элементом, расположенным пространственно между изоляционными элементами, размещенными на основании. Через сквозное отверстие изоляционных элементов, расположенное вдоль его продольной оси все три изоляционных элемента связываются в жесткую конструкцию фиксирующим элементом U-образной формы. Дополнительно введенный изоляционный элемент расположен в вершине «тpeyгoльникa» и фиксирующий элемент пронизывает его, причем прямой участок чашеобразной части фиксирующего элемента размещен внутри изоляционного элемента. Фиксирующий элемент U-образной формы крепится к основанию при помощи резьбового соединения.The cable fastening device according to the 2nd embodiment comprises a base 1 (Fig. 1), which can be made, for example, in the form of a profile with perforation and insulating elements 2 (Fig. L) movably fixed along its longitudinal axis. Between two insulating elements mounted on the base, two parallel cables are fixed. The third cable, which is the top of the triangle, is located on the base formed by cables parallel to each other. The cable of the top of the “triangle” is fixed by an insulating element located spatially between the insulating elements placed on the base. Through the through hole of the insulating elements located along its longitudinal axis, all three insulating elements are tied into a rigid structure by a U-shaped fixing element. An additionally inserted insulating element is located at the top of the “triangle” and the fixing element penetrates it, and a straight portion of the cup-shaped part of the fixing element is placed inside the insulating element. The U-shaped locking element is attached to the base using a threaded connection.
В соответствии с инструкцией по прокладке кабеля из сшитого полиэтилена кабель должен располагаться параллельно в одной плоскости или треугольником, при расположении кабелей треугольником кабели должны скрепляться вместе в треугольник в местах, расположенных по длине кабельной линии. Кабель «тpeyгoльникoм» в данном устройстве может крепиться в 2-х вариантах (фиг.l - 2-й вариант крепления кабеля треугольником; фиг.4, фиг.5 - 1-й вариант крепления кабеля треугольником, в 2-х исполнениях). По 1-му варианту, при расположении кабеля в «тpeyгoльник», на основании подвижно закрепляются изоляционные элементы и крепится кабель основания треугольника, затем изоляционные элементы вместе с прутками фиксируются пластиной с профильными концевыми выемками. Затем прутки используются как основание, на которое закрепляются изоляционные элементы, между которыми размещается кабель, изоляционные элементы фиксируются прутками из высокопрочного полимерного материала, причем крепление «тpeyгoльникoм» имеет два исполнения.In accordance with the instructions for laying a cable made of cross-linked polyethylene, the cable must be parallel to one plane or a triangle, when the cables are arranged in a triangle, the cables must be fastened together into a triangle in places along the length of the cable line. The “triangle” cable in this device can be mounted in 2 versions (Fig. 1 - the second option for attaching the cable with a triangle; Fig. 4, Fig. 5 - the 1st option for attaching the cable with a triangle, in 2 versions). According to the 1st option, when the cable is located in the “triangle”, insulating elements are movably fixed on the base and the cable of the triangle base is attached, then the insulating elements together with the rods are fixed with a plate with profile end recesses. Then the rods are used as the base on which the insulating elements are fixed, between which the cable is placed, the insulating elements are fixed with rods of high-strength polymer material, and the “triangle” mount has two versions.
При креплении кабеля по 1 и 2 варианту используются изоляционные элементы красной, желтой и зеленой расцветок, согласно фазировке кабеля, что приводит к безопасной работе при эксплуатации и проведении ремонтных работ. Изоляционные элементы имеют расцветку по фазам А-желтую, В-зеленую, С-красную, т.е. каждой фазе соответствует свой цвет изоляционных элементов, который сопровождает кабель от одной станции к другой.When attaching the cable according to option 1 and 2, insulating elements of red, yellow and green colors are used, according to the phasing of the cable, which leads to safe operation during operation and repair work. The insulating elements are colored in phases A-yellow, B-green, C-red, i.e. Each phase corresponds to its own color of insulating elements, which accompanies the cable from one station to another.
Устройство для крепления кабеля позволяет надежно крепить кабель с оболочкой из сшитого полиэтилена, повышается удобство монтажа, нет необходимости в дополнительной защите оболочки от механических повреждений. The cable fastener allows you to securely fasten the cable with a sheath of cross-linked polyethylene, increases the ease of installation, there is no need for additional protection of the sheath from mechanical damage.
