Abstract

The invention provides a low-calorific-value high-strength cable support and a manufacturing method thereof. The cable support includes a carrier and a support arm. The carrier is provided with a connecting member, and the connecting member is integrally formed with the carrier. The support arm is connected to the carrier through the connecting member. The low-calorific-value high-strength cable support and the manufacturing method thereof have the advantages that the cable support has high strength, the calorific value is low, the fire resistance performance is good, the structure is simple,the assembly is convenient and quick, the manufacturing process is simple, and the manufacturing process is efficient and energy-saving.

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...
