Example Embodiment

[0021] Example one:

[0022] A cross arm of a composite material distribution network with different colors. It includes a base 1. A number of mounting holes 2 for installing insulators are opened on the base 1. The upper surface of the base 1 is a convex arc-shaped plane. 1 From the inside to the outside, it includes a support layer 11 that provides support, an anti-wear layer 13 that prevents the support layer 11 from being worn, a colored layer 14 with a different color, and a protective layer that shows the color of the colored layer 14 and protects the colored layer 14 15. The support layer 11 is a steel plate made of 45# steel with a cross-section of "L". The wear layer 13 is a ceramic layer wrapped around the support layer 11, and a seal is injected between the wear layer 13 and the support layer 11 Glue 12 and sealant 12 are composed of the following weight percentages: 30% special resin, 20% plasticizer, 5% anti-fungal diluent, 5% anti-fungal agent, 3% hydrophobic agent,...

Example Embodiment

[0029] Embodiment two:

[0030] The thickness of the epoxy resin board is 5mm and the thickness of the polytetrafluoroethylene film is 0.01mm. The thickness of the epoxy resin board in the first embodiment is 2mm and the thickness of the polytetrafluoroethylene film is 0.02mm. The rest The technical features are the same as the first embodiment.

[0031] The epoxy resin board with a thickness of 5mm has extremely high breakdown voltage and reflects the color. At the same time, the internal steel plate has a thick protective layer, which is suitable for the installation of high-voltage transmission lines. It is thick, which greatly meets the needs of insulation. The thickness of the PTFE film only needs to be 0.01 mm to safely protect the colored layer 14 and reduce production costs.

Abstract

The invention discloses a composite power distribution network cross arm with phase colors. The composite power distribution network cross arm comprises a base and an insulator. A plurality of installation holes for installation of insulators are formed in the base. The upper surface of the base is an upward-protruding arc-shaped plane. The base comprises a supporting layer, an anti-abrasion layer, a coloring layer and a protective layer from interior to exterior, wherein the supporting layer provides supporting force, the anti-abrasion layer prevents the supporting layer from being abraded, the coloring layer has phase colors, and the protective layer reflects the phase colors of the coloring layer and protects the coloring layer. The supporting layer is a steel plate with an L-shaped cross section. The anti-abrasion layer is a ceramic layer wrapping the supporting layer. The coloring layer is a colorful epoxy resin plate. The protective layer is a polytetrafluoroethylene film. The cross arm is provided with the coloring layer, so that the phase colors can be prevented from being peeled off or faded, the bright phase colors are kept all the time, and meanwhile the labor intensity of operators is lowered.

Description

technical field [0001] The invention belongs to the field of power transmission equipment, and in particular relates to a composite material distribution network cross arm with phase color. Background technique [0002] At present, in the field of power facilities, the cross arm for transmission lines is an important supporting structural part of the transmission pole. One end of the cross arm is connected to the main body of the transmission pole, and the other end is hung with a transmission wire. [0003] Electrical equipment is generally divided into A, B, and C phases, which are required to be marked with yellow, green, and red respectively. At present, phase colors are generally achieved by pasting signs with phase colors on the outside of iron cross-arms or wooden cross-arms or by painting , when installing the distribution network cross arm, it will increase the process and increase the construction time, and the phase color of the sign or paint only forms a thin lay...
