Problems solved by technology

[0003] However, due to the inherent defects of the PVC material itself, that is, its poor toughness, especially its poor low-temperature toughness and low-temperature impact resistance, when the PVC-U electrical bushing is used in a low-temperature environment (0 ℃ and below), the product is extremely vulnerable. It becomes brittle, and the product will be brittle and cracked by a slight impact, causing construction difficulties and affecting the progress of the project

Embodiment Construction

[0016] The technical solutions in the embodiments of the invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only some, not all, embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] refer to figure 1 , a kind of anti-low temperature brittle electrical bushing, including an inner layer 3, the inner layer 3 is specifically a polychlorotrifluoroethylene structural layer, polychlorotrifluoroethylene has excellent low temperature resistance, and can be used in liquid nitrogen, liquid oxygen and liquefied natural gas No brittle cracks and no creep, under certain conditions it can be used close to absolute zero (-273°C). As an inner layer structure, it can ensure ...

Abstract

The invention relates to the technical field of electrical bushings, in particular to a low-temperature brittleness resistant electrical bushing which comprises an inner layer, a middle layer radially located outside the inner layer and an outer layer radially located outside the middle layer. The inner layer is specifically a polytrifluorochloroethylene structural layer, the middle layer is specifically a polyvinyl chloride structural layer, and the outer layer is specifically a linear low density polyethylene structural layer. The low-temperature brittleness resistant electrical bushing is reasonable in design, not only has the flame retardance and insulativity of a PVC-U electrical bushing, but also has good low-temperature toughness, impact resistance and pressure resistance, is not prone to brittle rupture in a low-temperature environment, the occurrence of the brittleness phenomenon of the PVC-U flame-retardant electrical bushing in a low-temperature environment is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electrical bushings, in particular to a low-temperature brittle electrical bushing. Background technique [0002] With the development of social economy, people have higher requirements for food, clothing, housing, transportation, etc. Housing is an indispensable part of people's life, which makes people's requirements for building decoration more and more strict. In home decoration, wires need to be threaded inside the wall. PVC-U electrical sleeves are used as threading pipes because of their high flame resistance, which can protect the insulation layer of wires and prevent the spread of flames. [0003] However, due to the inherent defects of the PVC material itself, that is, its poor toughness, especially its poor low-temperature toughness and low-temperature impact resistance, when the PVC-U electrical bushing is used in a low-temperature environment (0 ℃ and below), the product is extremely easy to ...
