The role of the power cable insulation layer of mining cable

The role of the mining cable power core insulation layer The function of the mining cable power core insulation layer The structure of the mining cable: the power core insulation layer: determines the insulation degree of the cable. It is the main basis for the distinction between high-voltage cable and low-voltage cable, and it is also a key factor for normal power transmission. Once its insulation is reduced, such a leakage current is formed: Electric 1 2 3 5 4 As long as the leakage signal is large enough, the relevant device of the switch can be captured and tripped.
The structure of the mining cable: the function of the power core wire semiconductor shielding layer: First, it is conductive. When the insulation of the power core wire insulation layer is lowered, the code numbers 3, 5 and 4 form a leakage branch; the second is to make the power core wire not interfere with other signals. . Note: When the cable is connected to the device and the cable is connected to the cable, the power cable and the cable cannot be connected together. Otherwise, the leakage fault will be reported.
The structure of the mining cable: the grounding core "4" is also generally referred to as internal grounding. No matter what power equipment under the mine, there must be an internal grounding column and must be connected to the grounding core "4" of the cable. Its role is to introduce leakage current into the earth.
