Description

Technical Field

[0001] This utility model relates to a cable support, particularly a metal cable support with a fiberglass liner. Background Technology

[0002] Metal cable supports are widely used in cable tunnels, cable manholes, integrated utility tunnels, and other projects due to their strength, toughness, ease of processing, and ease of installation. However, metal cable supports can easily cause eddy currents in cables, which consume electrical energy, generate heat, and affect cable heat dissipation. Cable liners, made of fiberglass, have excellent insulation properties and can protect cables from eddy currents. Therefore, a fiberglass cable liner is placed between the metal cable support and the cable to prevent the generation of eddy currents. This method is suitable for integrated utility tunnels, cable tunnels, cable manholes, and other projects. Summary of the Invention

[0003] To protect cables from the effects of eddy currents, this utility model provides a metal cable support with a fiberglass liner. The metal cable support with the fiberglass cable liner is not only strong and tough, easy to process and install, but also does not generate eddy currents, thus protecting the cable.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a metal cable bracket with fiberglass padding, including a metal cable bracket (1) and a fiberglass padding (2);

[0005] The metal cable bracket (1) includes a column (11) and a support arm (12); the column (11) includes a column width longitudinal surface (111), and the support arm (12) includes a support arm width longitudinal surface (121) and a support arm transverse surface (122). The support arm transverse surface (122) is vertically welded to the middle of the column width longitudinal surface (111); the column width longitudinal surface (111) has column through bolt holes (1111) at the middle of its upper and lower ends; the support arm width longitudinal surface (121) is a bearing surface, and support arm through bolt holes (1211) are provided near and away from the column (11);

[0006] The fiberglass gasket (2) is a cuboid with rectangular sides in both the transverse and longitudinal directions, including two parallel gasket width longitudinal surfaces (21) and gasket through bolt holes (22); one of the gasket width longitudinal surfaces (21) contacts the support arm width longitudinal surface (121); the gasket through bolt holes (22) penetrate through both gasket width longitudinal surfaces (21); the width of the gasket width longitudinal surface (21) is the same as the width of the support arm width longitudinal surface (121);

[0007] When the cable support is in operation, the fiberglass liner (2) is bolted to the support arm (12) through the liner through bolt hole (22) and the support arm through bolt hole (1211), and the column (11) is bolted to the manhole wall through the column through bolt hole (1111). The cable is located on another liner longitudinal surface (21) that does not contact the support arm longitudinal surface (121).

[0008] The metal cable bracket (1) is made of stainless steel, and the fiberglass liner (2) is made of glass.

[0009] The advantages of this utility model are:

[0010] The fiberglass gasket is made of fiberglass composite material as the main material, which has good insulation performance, electrical strength (can withstand 50kV voltage), wear resistance (friction coefficient <0.35), flame retardancy (oxygen index >26), and flame retardancy rating reaches V-0 level.

[0011] The metal cable bracket is made of stainless steel as the main material, which has good load-bearing capacity and resistance to deformation. Attached Figure Description
