Description

Technical Field

[0001] The present invention relates to the technical field of drainage line erection, and in particular to a special insulating bracket and a hanging method for a drainage line for live working in a distribution network. Background Art

[0002] The distribution network refers to a power grid that receives electric energy from the transmission network or regional power plants and distributes it locally or step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, poles, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid. The drainage line of the distribution network is an important component of the distribution network system. The drainage line is used to guide or connect the current in the distribution network to transfer electric energy from one device or system to another. The design and installation of drainage lines are crucial to the safe operation of the distribution network because they need to withstand the transmission of current and ensure that the current can flow to the target location stably and efficiently. When laying out over long distances, special insulating brackets are required to suspend and fix the drainage lines.
