Abstract

The invention provides a low-calorific-value high-strength cable support and a preparation method thereof. The preparation method comprises the following steps of S1, preparing a matrix material; S2,preparing a mixture; S3, fiber soaking; S4, curing and cutting; S5, die filling; S6, curing and molding; S7, demolding; and S8, post-curing. According to the low-calorific-value high-strength cable support and the preparation method thereof, the cable support has the advantages of being high in strength, low in calorific value, good in fireproof performance, simple in structure, convenient in assembly, simple in the preparation process, efficient and energy-saving in the preparation process and the like.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a cable support, in particular to a low calorific value high-strength cable support and a preparation method thereof. Background technique [0002] Cable brackets are mainly used to support and fix power supply cables. Generally, cable brackets are installed in rail transit, subways, and tunnels. [0003] For a long time, the erection of cables has mainly been supported and fixed by cable brackets made of angle irons. Angle iron brackets are usually assembled from angle iron profiles through welding or fasteners. The traditional angle iron bracket has many defects: first, it is difficult to manufacture: the production process of the angle iron bracket consumes a lot of energy, many processes, a long cycle, and the quality cannot be guaranteed; second, the energy loss is large: because the metal cable bracket is a conductor, it is easy to The eddy current interaction...
