Multifunctional 10kV live working electric insulating cross arm and working method

The invention provides a multifunctional 10kV live working electric insulating cross arm and a working method, and relates to the technical field of insulating cross arms. The multifunctional 10kV hot-line work electric insulation cross arm comprises a cross arm body, an upper end fixing device and a wire fixing device, and the invention further provides a using method of the multifunctional 10kV hot-line work electric insulating cross arm. The method comprises a triangular lifting hook fixing and using method, a linear lifting hook fixing and using method, a triangular hoop fixing and using method, a linear hoop fixing and using method and a linear bucket arm vehicle supporting and fixing and using method. Switching between a linear cross arm and a triangular cross arm is achieved, the problem that time and labor are wasted when wires are triangularly arranged through the linear cross arm is solved, and the problem that the wires are vertically arranged and cannot be fixed is solved. The problem that the cro
