For a long time, the material of cable brackets mainly includes metal angle iron cable brackets and cement cable brackets. Because metal brackets are simply rolled and formed from steel or angle iron, they are economical and easy to obtain, so the angle iron cable brackets are longer. The main option for laying power cables as a domain has been used for a long time, but the material weakness of the angle iron brackets has become increasingly prominent during use:

1. Electrical damage caused by cable and metal eddy currents, accounting for more than 50% of cable iron loss;

2, easy to rust is susceptible to corrosion, anti-rust paint and hot zinc technology can not be avoided, low service life;

3. Limited use in harsh environments such as subways, tunnels, chemical companies, rainy or humid coastal or coastal salt spray;

4. The production process consumes a large amount of energy, has many processes, and has a long cycle.

FRP cable bracket is a steel frame made of composite material made of synthetic resin as binder, glass fiber and its products as reinforcing materials. It is suitable for cable laying of various cable sections, and the tensile and bending strength are very good. it is good.

1. A composite material made of synthetic resin as a binder, glass fiber and its products as reinforcing materials, called glass fiber reinforced plastic. Because of its high strength, it can be compared with steel, so it is also called FRP.

2, the weight of lightweight high-strength FRP is only 1.4-2.0, that is, only 1/4-1/6 of ordinary steel grid, which is about 1/3 lighter than aluminum, and the mechanical strength can reach or exceed the level of ordinary carbon steel. For example, some epoxy and unsaturated polyester glass reinforced plastics have tensile and flexural strengths of more than 400 Pa, which have reached or exceeded the level of certain special alloy steels in terms of specific strength.

3, excellent chemical resistance, glass steel and ordinary metal electrochemical corrosion mechanism is different, it is not conductive, there will be no ions dissolved in the electrolyte solution, so the atmosphere, water and general concentration of acid, alkali, salt, etc. The medium has good chemical stability, especially strong non-oxidizing acids and a good range of media in a wide range of pH values. In the past, some media that could not be used with stainless steel, such as hydrochloric acid, chlorine, carbon dioxide, dilute sulfuric acid, sodium hypochlorite and sulfur dioxide, can now be solved with FRP.
