Description

Technical field [0001] The present invention involves a photoelectric composite flame retardant high -voltage cable. It is a cable for large coal mining machinery devices. It specifically involves a high -pressure cable for photoelectric composite flame retardant. Background technique [0002] With the increase of the total installation of the coal mining machine, it is an inevitable trend to increase the power supply voltage of the working surface. At present, the voltage level of 10kV and below cables needs to be increased to 15kV or even 30kV.At the same time, based on networked and modular distributed coal mining electrical control systems, a large number of optical cables need to be used.The conversion has been greatly affected. [0003] Subsequently, the application number 200910047226.6 Application date was the patented technical solution on March 09, 2009. Its technical solution is: a high -voltage cable of a photoelectric composite port roll, including three high -voltag...
