The full name of the carbon fiber wire is carbon fiber composite core aluminum stranded wire (ACCC), the wire from the beginning of this century has only been used for a relatively short period of more than ten years, there is a certain amount of experience in the application. Carbon fiber wire has high strength, lightweight, high modulus of elasticity, small coefficient of linear expansion, small arc sag, small line loss, large capacity (allowing high temperature), corrosion resistance, long service life, and other characteristics. Especially suitable for coastal, mining areas corrosion intensity, high fouling strength, the wire is easy to dance the use of the environment.
10KV overhead cable transmission line common faults are 7 kinds
1 Single-phase grounding fault
Single-phase grounding is the most common fault in the power distribution system, mostly occurring in wet and rainy weather. Single-phase grounding not only affects the normal power supply of users, but also Hunan Sunshine Electronics School maintenance experts believe that: it may produce overvoltage, burn equipment, and even cause an inter-phase short circuit and expand the accident.
With the continuous upgrading and construction of power grids and transportation infrastructure, transmission lines “three across” related issues are becoming more frequent. Such as improper handling, which will likely lead to significant public safety and grid security incidents. So for the transmission lines “three across” section, construction standards and other aspects must be strictly controlled. This paper provides a summary of this issue.
