yjv-3*35 2*16 power cable 
Full name of product: copper core (aluminum core) cross-linked polymer ethylene Insulated PVC sheathed power Cable ；
Product structure: Yjv cable is composed of conductor, polyethylene insulator, filler (nylon, pvc composite material, etc.), PVC outer sheath from the inside out, Yjv-3 * 35 2 * 16 power cable
Among them, most conductors are copper cores. At present, copper conductors are widely used in the market, while aluminum conductors are seldom used due to poor conductivity and lack of standards; The filler is mostly made of nylon and plays a role in protecting the cable core, which is equivalent to putting a piece of "clothes" on the cable core; If it is armored power cable, a layer of steel tape armouring will be added between the filler and sheath, so that the cable can be buried underground to play a compressive role. The model of steel tape armored yjv cable is yjv22; PVC sheath is our common PVC material.
Product executive standard: GB/T12706.1-2008, IEC60502-1-1997
Conductor material: copper material and aluminium alloy Material, wherein, the model code of aluminum core cable is yjlv; Yjv-3 * 35 2 * 16 power cable
Rated voltage: Yjv cables are generally divided into four types: voltage, high-voltage, medium voltage and low-voltage cables. Usually, low-voltage power cables are mostly used. High voltage and high-voltage are generally used for long-distance and long-distance power transmission. Medium and low-voltage power cables (35 kV and below).
Temperature: the allowable working temperature of cable conductor for high and long term is 70 ℃. In case of short circuit (long duration not more than 5s), the high temperature of cable conductor is not more than 160 ° C, and the ambient temperature during cable laying should not be less than 0 ° C.
Purpose: power cable for distribution engineering, power transmission engineering Wire and cable , electromechanical and hydropower installation engineering cable, power transmission cable, power supply installation system control system, etc
Precautions for installation: when laying cables, the small bending radius shall not be less than 10 times of the outer diameter of the cable. The yjv/yjlv cable can be laid indoors, in trenches and pipes, or buried in loose soil, and cannot bear external forces. The yjv22/yjlv22 cable is laid underground and can bear the external mechanical force, but cannot bear a large tensile force. Special tools such as paying off rack and guide roller shall be used for cable laying to prevent mechanical damage and keep away from heat sources. When cables are laid through pipes, the inner diameter of the pipe shall not be less than 1.5 times of the outer diameter of the point. When multiple cables are laid through pipes, cable extrusion is prohibited. The total area of the cable shall not exceed 40% of the total area in the pipe.
Yjv cable product classification: ordinary type, flame retardant type, fire-resistant type, low smoke halogen free type
