Gadi
Maximum long-term allowable working temperature of the cable conductor is 70°C, when the cable conductor is short-circuited (the maximum duration does not exceed 5S), the maximum temperature of the cable conductor does not exceed 160°C, and the ambient temperature when laying the cable should not be lower than 0°C.
Istifanan
power distribution engineering power cables, power transmission engineering wires and cables, electromechanical and hydropower installation engineering cables, power transmission cables, power supply installation system control systems, etc
Tushen istifana
Minimum bending radius is not less than 10 times the outer diameter of the cable when laying the cable, and the YJV/YJLV cable is laid indoors, in the channel and pipe, or can be buried in loose soil, and cannot withstand the action of external forces. YJV22/YJLV22 cables are laid underground and can withstand mechanical external forces, but they cannot withstand large tensile forces. Special tools should be used for cable laying, such as pay-off frames, guide rollers, etc., to prevent mechanical damage during the laying process and stay away from heat sources. When the cable is laid through the pipe, the inner diameter of the pipe is not less than 1.5 times the outer diameter of the point, and the cable is prohibited from being squeezed when the cable is threaded, and the total area of the cable does not exceed 40% of the total area in the pipe.
YJV cable product classification: ordinary type, flame retardant type, fireproof type, low smoke halogen-free type
