Abstract

The invention discloses a weak current casting pipe and a manufacturing method thereof. The method comprises the following steps that a substrate is arranged at one end of a first casting pipe, and a positioning rod is arranged at a preset position on the substrate in a penetrating manner and extends into the first casting pipe; a second casting pipe is arranged on the positioning rod in a sleeving manner; concrete is poured between the inner wall of the first casting pipe and the outer wall of the second casting pipe; and after concrete pouring is completed, the positioning rod is taken out. The second casing pipe is arranged in the first casing pipe, and the concrete is filled and plugged between the first casing pipe and the second casing pipe, so that the problems of cracking of the first casing pipe and water seepage and water leakage caused by untight plugging of the end part of the first casing pipe or the second casing pipe are solved.

Description

technical field [0001] The invention relates to the technical field of electrical wiring, in particular to a weak current bushing and a manufacturing method thereof. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, in the existing technology, wires and electrical bushings are used in the fields of construction, decoration and fire protection. Due to the high temperature generated by the short circuit of the wires, it may cause a fire, making the wires during use Potential safety hazards are caused, especially in weak current projects that are very close to life, and special attention should be paid to them. However, the existing fireproof casings for weak current projects are too troublesome to connect due to the limited length, and weak current lines are easily damaged due to extrusion. Therefore, it is an effective method to solve the above-mentioned problems to set electrical bushings outside th...
