Description
Technical Field
The invention relates to the field of electric power engineering, in particular to a pulley bracket for mounting a 10kV insulating cross arm wire.
Background
The excellent mechanical tensile property and electrical insulating property of the composite material promote the vigorous popularization of the insulating cross arm of the distribution network. Most 10kV distribution network transmission line towers are cement towers, iron cross arms are mounted at tower heads, and insulators are connected with the iron cross arms. The insulation level of the distribution network is mainly determined by the insulation level of the insulator, and after the insulation cross arm replaces an iron cross arm, the insulation level of the line can be greatly increased, and good overvoltage resistance is achieved. Before the installation of a 10kV distribution network wire, a wire hanging pulley is installed on an iron cross arm, a newly-built wire passes through a pulley upper tower, and finally after the arrangement of a tension section wire is completed, the wire is transferred to an insulator through the pulley to be subjected to wire fixing operation. Because the load of the wire is large, the pulley mounting position is close to the insulator mounting position under the normal condition, and the constructor is favorable for transferring the wire to the insulator end. The 10kV insulating cross arm base material adopts a glass fiber rod, has good mechanical tensile property and electrical insulating property, but is easy to age under an ultraviolet environment, so that the outer layer of the insulating cross arm is provided with a silicon rubber full coating. For a newly-built circuit, if a wire hanging pulley is in contact with silicon rubber during installation, the silicon rubber is easily damaged, an internal glass fiber base material is exposed under ultraviolet rays, potential safety hazards are caused, and the insulating cross arm is good in electrical performance.
