RVV是铜芯聚氯乙烯绝缘聚氯乙烯护套软电缆.有绝缘,有护套,二芯及以上.RVS是铜芯聚氯乙烯绝缘对绞软线,只有绝缘层,没有护套,只有二芯规格.BVR电线是一种配电柜专用软电线，也叫二次线。采用铜芯聚氯乙烯的绝缘软电线,其应用于固定布线时要求柔软的场合。深受广大电工及建筑装饰人员喜欢。装修中水电改造都是隐蔽工程，暗铺的电线是不可以随意更换的，所以电线的选择直接关系到日后的用电安全。BV和BVR线的区别：材质相同，都是铜芯聚氯乙烯绝缘线，区别在于：BV线是较硬的单芯硬线，BVR是较软的多芯软线，相同面积的所承受的电流相同。

　　2、产品标准：Q/TYL411-91《聚氯乙烯绝缘和护套信号电缆》3、产品使用特性：电缆导电线芯的长期允许工作温度应不超过+65℃。敷设时电缆的温度应不低于-5℃，弯曲半径应不小于电缆外径的10倍。4、电缆型号和名称型号名称使用范围PVV22聚氯乙烯绝缘聚氯乙烯护套内钢带铠装信号电缆敷设在室内、电缆沟中，管道内及地下。

　　一、产品简介本产品适用于额定电压1000V及以下对于防干扰性要求较高的电子计算机和自动化连接用电缆。电缆地线芯绝缘采用具有抗氧化性能的K型B类低密度聚乙烯。聚乙烯的绝缘电阻高，耐电压好，介电系数小和介质损耗温度和变频率的影响也小，不但能满足传输性能的要求，而且能确保电缆的使用寿命。
In order to meet the needs of the market, our factory has developed shielding and flame-retardant control cables in recent years on the basis of producing ordinary plastic insulation control cables.

Low smoke zero halogen cables use features: 1. The cable of rated voltage UO/U: 450/750 v ac polyolefin UO/U for 0.6/1 kv2. The long-term working temperature of cable: - 20 ℃ to 90 ℃ and 40 ℃ - 105 ℃ 3. Recommend a bending radius: no armoured cable should be not less than 6 times of cable diameter, structure of armoured or copper tape screened cable should be not less than 12 times of cable diameter.

RS485 bus due to its wiring is simple, stable and reliable and widely used in video surveillance, access control intercom, building alarm and other fields, however, because there are a lot of in the process of 485 bus wiring is not completely accurate concept leads to many problems. Some wrong ideas will now be clarified.

二极管是电子电路中很常用的元器件，非常常见，二极管具有正向导通，反向截止的特性。在二极管的正向端(正极)加正电压，负向端(负极)加负电压，二极管导通，有电流流过二极管。在二极管的正向端(正极)加负电压，负向端(负极)加正电压，二极管截止，没有电流流过二极管。这就是所说的二极管的单向导通特性。下面解释为什么二极管会单向导通。二极管为什么只能单向导电？二极管是由PN结组成的，即P型半导体和N型半导体，因此PN结的特性导致了二极管的单向导电特性。
