Composite nylon cable bracket

Abstract

The invention relates to a composite nylon cable bracket. The composite nylon cable bracket comprises a support seat and a support frame, wherein the support seat is of a channel steel structure, and a fixed bolt hole and a plurality of square holes which are uniformly distributed at intervals and are used for fixedly clamping the support frame are formed in the support seat; the support frame is made of nylon composite materials and is integrally formed, the cross section of the support frame is in a T shape, and the support frame comprises an upper pedestal which is used for bearing a cable and a lower base which is used for supporting the pedestal; and clamping grooves which are clamped with the square holes in the support seat are formed in one end of the support frame. According to the composite nylon cable bracket, the support frame is made of nylon, so that the composite nylon cable bracket has the advantages of high electrical insulation, low comprehensive cost, high corrosion resistance, no aging, long service life, no pollution in installation and use, no harm to bodies, high installation and connection strength, convenience in construction and low construction cost.

Description

technical field [0001] The invention relates to the field of power systems, and specifically discloses a composite nylon cable support. Background technique [0002] There are many types of cable brackets used in the power system. The use of cable brackets makes the cables arranged neatly and is easy to maintain; the cables can be adjusted and erected in layers to maintain a certain distance, which is good for heat dissipation; various cables can be laid separately to avoid mutual influence; prevent The cable is subject to flooding, mechanical damage, etc. [0003] The traditional support is mainly based on angle steel support, but with the application of practice, it increasingly shows many shortcomings: [0004] (1) The consumption of steel is relatively large, it is easy to corrode and rust, and the service life is short, and the rust is easy to scratch and wear the insulating layer of the cable surface, which affects the service life of the cable; [0005] (2) The cons...

AI Technical Summary

Problems solved by technology

[0004] (1) The consumption of steel is relatively large, it is easy to corrode and rust, and the service life is short, and the rust is easy to scratch and wear the insulating layer of the cable surface, which affects the service life of the cable;

[0005] (2) The construction workload is heavy, the installation is inconvenient, and the construction period is long;

[0006] (3) High maintenance costs, affecting the safety and trouble-free service life of power and communication facilities;

[0007] (4) Using a metal bracket, the current flowing through the cable will generate a magnetic field, resulting in the formation of a magnetic field closed loop (circulation) between the two bracket angle steels, which will increase the temperature of the cable, increase the current loss, and further increase the temperature of the circulation. It is easy to form a strong arc and damage the power cable and metal support. In order to solve this problem, measures such as thickening the cable are mainly taken at present, but the cost of the power transmission equipment will increase.

[0008] Some also use glass fiber reinforced plastic brackets, but there are many disadvantages in the process of installation, such as easy aging and slag, short service life, polluting the environment, and causing physical harm to construction workers (skin itching)
