Embodiment 1

[0017] The preparation of embodiment 1 cable core

[0018] Pass the carbon fiber untwisted yarn through the creel 1, enter the storage tank 3 filled with epoxy resin glue through the guide felt plate 2, and dip in the glue. The ultraviolet absorber RMB and light stabilizer HPT in the glue are 0.1% of the epoxy resin quality. %, 0.1%, the quality of the acid anhydride curing agent is the sum of the quality of the ultraviolet absorber RMB, light stabilizer HPT, and epoxy resin, and then enters the preforming mold 4.

[0019] The reinforcing material coming out of the preforming mold 4 enters the forming mold 5 with a heating plate for curing. The forming mold 5 is 650mm long and has a cavity diameter of 4.5mm, and is divided into three temperature zones: 140°C, 170°C, and 140°C. After solidification, pull out from the forming mold 5 by the pulling machine 6, and obtain the inner layer of the cable core.

Embodiment 2

[0022] The preparation of embodiment 2 cable core

[0023] Pass the carbon fiber untwisted yarn through the creel 1, enter the storage tank 3 filled with phenolic resin glue through the guide felt plate 2, and dip in the glue. The ultraviolet absorber UV-O and light stabilizer LQ-292 in the glue are the quality of phenolic resin. 3%, 3%, the quality of the anhydride curing agent is the sum of the quality of the ultraviolet absorber UV-O, the light stabilizer LQ-292, and the phenolic resin, and then enters the preforming mold 4.

[0024] The reinforcing material coming out of the preforming mold 4 enters the forming mold 5 with a heating plate for curing. The forming mold 5 is 650mm long and has a cavity diameter of 4.5mm, and is divided into three temperature zones: 140°C, 170°C, and 140°C. After solidification, pull out from the forming mold 5 by the pulling machine 6, and obtain the inner layer of the cable core.

Embodiment 3

[0026] The reinforcing material coming out from the preforming mold 4 enters the forming mold 5 with a heating plate to solidify. Forming mold 5 is long 650mm, and mold cavity diameter is 6.5mm. After solidification, pull out from the forming mold 5 by the pulling machine 6, and obtain the inner layer of the cable core. Example 3 Cable core heat resistance (aging) performance test

[0027] Put the cable core containing ultraviolet absorber and light stabilizer, and the cable core without ultraviolet absorber and light stabilizer into ovens with temperatures of 140°C, 160°C, 180°C, 200°C, and 240°C for 400 hours; After heating, take it out and let it cool naturally in the air to room temperature; install wedge-shaped tension clamps at both ends of the cable and test the tensile force on a 500KN tensile testing machine. The test results are shown in the table below. The tensile force of the former is higher than that of the latter, indicating that the cable core containing ul...

Abstract

The invention relates to a composite material cable core which is composed of an inner layer and an outer layer; heat-resisting resin is taken as a matrix for the inner layer, and a high-strength ultra-long continuous fiber is taken as a reinforcing material; and hindered anime light stabilizers and ultraviolet absorbers are added in the heat-resisting resin of the inner layer and the outer layer. The cable core provided by the invention has favorable performances of ultraviolet resistance, aging resistance and even heat resistance.

Description

technical field [0001] The invention relates to a composite material cable core, in particular to a composite material cable core with the properties of anti-oxidation, anti-ultraviolet and high temperature resistance. Background technique [0002] With the continuous and stable development of my country's economic aggregate, energy has become a key factor restricting economic development. Electric power is the main body of energy, and power transmission is the main body of energy transmission. Therefore, power grid security is an important part of national security. In 2005, my country's power generation installed capacity reached 500 million kilowatts, and in 2010 it reached 900 million kilowatts. In the Eleventh Five-Year Plan, 38,000 kilometers of high-voltage lines will be newly built, and at the same time, the old lines will be vigorously transformed, especially in the economically developed eastern coastal areas. [0003] The application number is 200710034744.5, wh...
