Description

Technical Field

[0001] The invention relates to the technical field of cable installation, and in particular to a novel cable installation and fixing device. Background Art

[0002] Cable laying in electrical shafts is a common link in cable laying construction. It is mainly used to pass the main cable from the bottom of the building through the electrical shaft upward layer by layer. Since the cable body is thick and heavy, the higher the floor height, the heavier the total weight of the cable. For those high-rise cable threading, in order to make the cable stable and not fall in the later stage, it must be tied and fixed to the inner wall of the electrical shaft at a certain distance.

[0003] The traditional binding and fixing method is to use the existing relatively thin skinned electric wires to tie them to the angle steel fixed on the wall. Although this method is effective in a short time and easy to operate, the long-term compression of the cable skin by the binding wires will cause damage to the cable skin and even cause leakage. Therefore, we propose a new type of fixing device for cable installation in electrical wells. Summary of the invention
