重庆**YJV电缆|重庆高端电线电缆|重庆高强度LGJ钢芯铝绞线

重庆电线电缆中yjv电缆是电力电缆中较常用的一种，甚至如今很多人说到电缆都泛指的是yjv电缆。yjv电缆作为电力传输中的主干电缆，有如人体血管中的动脉血管，或者是一颗树的树干，说明了其在电力传输中的重要地位。yjv电缆一般常见于城市的地下通道（井盖地下）或者埋在地下，经常有施工队施工时将电力电缆挖断导致大面积的停电事故，说的就是电力电缆。yjv电缆是电力电缆中较常用的一种，甚至如今很多人说到电缆都泛指的是yjv电缆。yjv电缆作为电力传输中的主干电缆，有如人体血管中的动脉血管，或者是一颗树的树干，说明了其在电力传输中的重要地位。yjv电缆一般常见于城市的地下通道（井盖地下）或者埋在地下，经常有施工队施工时将电力电缆挖断导致大面积的停电事故，说的就是电力电缆。以下是yjv电力电缆的一些简单介绍——
YJV电缆产品全称：铜芯（铝芯）交联聚乙烯绝缘聚氯乙烯护套电力电缆；
产品结构：yjv电缆由内而外的组成部分分别为导体、聚乙烯绝缘体、填充物（尼龙、pvc复合材料等）、聚氯乙烯外护套，
其中，导体多为铜芯，目前铜导体是市面上使用较广的导体材料，铝导体因导电性能较差以及缺乏标准，使用较少；填充物多为尼龙等材质，起到保护线芯的作用，相当于给电缆线芯穿上了一件“衣服”；如果是铠装电力电缆则会在填充物和护套之间加上一层钢带铠装，目的是电缆埋在地下起到抗压的作用，钢带铠装yjv电缆型号为yjv22；聚氯乙烯护套就是我们常见的pvc材料了。
产品执行标准：GB/T12706.1-2008、IEC60502-1-1997标准
导体材料：铜材料和铝合金材料，其中，铝芯电缆型号代号为yjlv；
额定电压：一般将yjv电缆分为**高压、高压、中压、低压电缆四种，而平时使用较多就是低压电力电缆，高压和**高压一般都用于长距离和**长距离电力传输，中、低压电力电缆（35千伏及以下）。
温度：电缆导体的较高长期允许工作温度为70℃，短路时（较长持续时间不**过5S），电缆导体的较高温度不**过160°C，敷设电缆时的环境温度不应该低于0°C。
用途：配电工程电力电缆,电力传输工程电线电缆,机电水电安装工程电缆，电力输送电缆，供电安装系统 控制系统等
安装注意事项：电缆敷设时较小弯曲半径不小于电缆外径的10倍，yjv/yjlv电缆敷设在室内，沟道及管子内，也可埋在松散的土壤中，不能承受外力作用。yjv22/yjlv22电缆 敷设在地下，能承受机械外力作用，但不能承受较大拉力。电缆敷设应采用**工具，如放线架，导辊等，敷设过程中防止机械损伤，远离热源。电缆穿管敷设时，管道内径不小于点按外径的1.5倍多，多跟电缆穿管时禁止电缆挤压，电缆的总面积不**过管内总面积的40%。
yjv电缆产品分类：普通型、阻燃型、耐火型、低烟无卤型
Is one of the most commonly used power cable YJV cables in Chongqing electric wire and cable, even now many people said cables are generally refer to is YJV cable. YJV cable as the main cable in the power transmission, such as the artery in the human blood vessel, or the trunk of a tree, it shows its important position in the power transmission. Cable YJV common to urban underground passage (covers underground) or buried in the ground, there is often a construction team, construction of the power cable Waduan lead to large area power outages, said is the power cable. YJV cable is one of the most commonly used in power cable, even now many people said the cable refers to YJV cable. YJV cable as the main cable in the power transmission, such as the artery in the human blood vessel, or the trunk of a tree, it shows its important position in the power transmission. Cable YJV common to urban underground passage (covers underground) or buried in the ground, there is often a construction team, construction of the power cable Waduan lead to large area power outages, said is the power cable. Here are some brief introduction of the YJV power cable.
YJV cable products full name: copper core (aluminum core) cross linked polyethylene insulated and PVC sheathed power cable;
Product structure: YJV cable from the inside and outside of the components are conductor, PE insulation, filler (nylon, PVC composite materials, etc.), PVC outer sheath,
Wherein, the conductor is a copper core, the copper conductor is conductor materials most widely used in the market, aluminum conductor because of low conductivity and the lack of standard, use less; filler multiple nylon material to protect the core role, is equal to the cable core is put on a "clothes"; if it is armored power cable is in filled with a layer of steel tape armored and jacket, the purpose is to function of the cable buried in the underground to the compressive, steel tape armoured YJV cable type to; PVC sheath is our common PVC material the.
Product implementation standards: GB/T12706.1-2008, IEC60502-1-1997 standard
Conductor material: copper material and aluminum alloy material, among them, the aluminum core cable type code is yjlv;
Rated voltage: the YJV cable is divided into ultra high-voltage, high-voltage, medium voltage and low voltage cable four, and usually use is the largest low-voltage power cable, high-pressure and ultrahigh high for long distance and long distance power transmission, low and medium voltage power cable (35 kV and below).
Temperature: the conductor is the highest for the allowable working temperature of 70 DEG C, short circuit (the longest duration of not more than 5S), no more than 160 DEG C, the highest temperature of cable conductor, cable laying, the ambient temperature should not be less than 0 DEG C.
Application: distribution power cable, power transmission engineering electric wire and cable, electrical and mechanical installation of electrical and hydro power cable, power transmission cable, power supply installation system control system, etc.
Installation notes: the minimum bending radius of cable laying is not less than 10 times the diameter of the cable, yjv/yjlv cable laying indoors, ditch and pipe, but also can be buried in the loose soil, can not withstand the external force. Yjv22/yjlv22 cable laid in the ground, can withstand the mechanical force, but can not bear large tension. Cable laying should use special tools, such as the wire frame, guide roller, etc., to prevent mechanical damage, away from the heat source. When the cable is put in pipe, the inner diameter of the pipe is not less than 1.5 times of the outside diameter, and the cable is forbidden to be pressed. The total area of the cable is not more than 40% of the total area of the pipe.
YJV cable product categories: ordinary type, flame retardant, fire resistant, low smoke halogen free type。
