Description
Technical Field
The invention relates to a sheath material for cable molding, in particular to a high-wear-resistance sheath material for cables and a preparation method of the sheath material.
The sheath material is particularly suitable for preparing sheath layers of cables serving in frequent torsion and friction working conditions, such as the cables for wind driven generators.
Background
The wind power generator mainly comprises a tower drum, a frame supported by the tower drum, a wind wheel and the like, and the frame is also provided with a related transmission system, a yaw system, a hydraulic braking system, a generator, a control and safety system and other mechanisms. The necessity of signal transmission such as power, control and/or communication exists between most of the components and/or mechanisms of the wind power generator, which requires connecting corresponding power cables, control cables and/or communication cables between the components and/or mechanisms, and in general, dozens of cables with different sizes are arranged in one wind power generator.
Due to the operational characteristics of the wind turbine, the wind turbine needs to frequently swing along with the change of the natural wind direction and/or the wind power, and most internal components and/or mechanisms need to be frequently twisted, so that the cable, which is a component of the wind turbine, is correspondingly twisted. Dozens of cables of the wind power generator are arranged in a non-scattered manner, and a plurality of cables are normally bundled together in a bundle and arranged regularly. In the frequent twisting of the cable bundle, the cables frequently rub against each other, and the wear resistance of the sheath of the cable is tested under the working condition.
At present, the commonly used sheath material of the wind driven generator cable is generally prepared by taking chloroprene rubber, chlorosulfonated polyethylene rubber and/or polyurethane elastomer and the like as main bodies and adding other proper components, and the cable formed by the sheath material can meet the low-temperature torsion performance of minus 40 ℃ and other general requirements. However, the abrasion resistance of the formed cable under the working conditions of frequent torsion and friction is not fully considered by the sheath material, i.e. the abrasion resistance of the sheath material is poor, and the technical requirements of the wind driven generator cable under the working conditions of frequent torsion and friction cannot be met. The wind driven generator is formed by adopting the cables made of the sheath materials, the cables run in a frequently twisted working condition environment, the cable surface layers of the cables of the cable bundles can be damaged due to frequent mutual friction, the damage is most common particularly on the wind driven generator which runs in a wind field maintained for 2-3 years, the abrasion and powder falling of the sheath layers of partial cables of the wind driven generator due to friction can be often found, serious people even find that the sheath layers are completely worn, the internal insulating layers can be seen, and the phenomenon seriously affects the stable, safe and long-term running of the wind driven generator.
Therefore, the sheath material of the cable (such as a cable for a wind driven generator) which is in service in the working condition of frequent torsion and friction needs to be improved, so that the sheath material can effectively meet the specificity of the application working condition.
