There are many kinds of cable bracket. If it is divided into three kinds according to the surface treatment in the manufacturing process, there are Angle iron hot-dip galvanized cable bracket, Angle steel plastic-dipped cable bracket, Angle steel hot-dip galvanized cable bracket and so on. From the installation of cable bracket, there are embedded cable bracket, inserted cable bracket, bolted cable bracket, combined cable bracket and so on. Among them, the Angle iron bracket is commonly used in the past cable bracket.

The so-called Angle iron bracket refers to the Angle iron profile by welding or fastener splicing assembly, in the production process, the need for large energy consumption, many processes, long cycle, and product quality cannot be guaranteed, in many harsh environmental conditions, such as subway, tunnel, chemical enterprises, rainy wet or coastal salt spray occasions, the use of Angle iron bracket is easy to rust, high maintenance costs of facilities, The service life is also shorter; Even if also with external paint or hot dip galvanizing technology treatment, in order to achieve the purpose of rust prevention and corrosion, but still can not fundamentally solve the problem of rust.

Therefore, the cable bracket made of composite materials is mostly used at present, such as fiberglass cable bracket, which is composed of resin, glass fiber and filler (phenolic resin, epoxy resin and unsaturated resin as binder, glass fiber and its products as reinforcement materials), and then after molding, molding process is safe and reliable. Therefore, it has the characteristics of corrosion resistance, light specific gravity, strong electrical insulation, excellent fire performance and long service life. It is suitable for horizontal cable laying.

But in fact, whether it is Angle iron bracket or fiberglass cable bracket, their role is similar. The cable is set up in layers to maintain a certain distance, which is conducive to heat dissipation. Various cables can be laid separately to avoid mutual influence; The cable can be arranged neatly, easy to maintain; Hold up the cable to prevent flooding and mechanical damage.

Well, the above is about the relevant knowledge of cable support, especially "what are the commonly used cable support", I hope you can understand, and then correctly choose the appropriate cable support to lay the cable.
