The cable is insulated by full-chromatograph solid polycondensation. The insulated wire is twisted into a pair of twisted wires. Suitable material of cable core is added to the cable core, and the plastic coated aluminum band shielding layer and the black outer expansion sleeve with the length mark in the counting order can be completed. Junction wire: solid annealed copper wire. Copper wire diameter is 0.32, 0.4, 0.6, 0.8 (mm).
HYA全塑市话电缆主要电气性能：1.直流电阻:20℃,0.4≤148Ω/km0.5≤95.0Ω/km0.6≤65.8Ω/km0.8≤36.6Ω/km。2.绝缘电气强度：导体之间1min1kv不击穿导体与屏蔽1min3kv不击穿。
Steel tape armoured mainly as the radial mechanical protection layer of the cable, and it also have additional total shielding effect, especially steel tape armoured and copper wire, copper tape screened, is adopted two different shielding materials, play a complementary role in electromagnetic wave shielding, shielding effect will be better.
三态R-S锁存触发器CC4044B。内部电路结构与引脚功能见下图。图CD4044B三态R-S锁存器将基本的R-S触发器加以改造，如在输出侧增设传输开关，就可得到具有三态传输功能的R-S触发器。从其内部电路结构可看出，a)增加了EN使能控制端，高电平为通态，低电平为关态；b)增加了受控输出级，为三态输出模式，当EN端为低电平时，输出级相对于外部电路，为高阻态。从检修角度出发，我们需要注意的着重点是在线如何确定芯片好坏，并找到（引脚功能、尺寸适宜的）替代元件。

（包括农村局用）二． 电缆适用温度为-10℃～50℃，电缆安装时的环境温度不低于0℃。弯曲半径不小于电缆直径的10倍。应用：室内外布线。。主要用于管道敷没，在架空安装时需要用吊线支承。
Flame-retardant cable: the electric wire and cable are produced by external heating. In order to achieve the purpose of flame retardant, the three elements must be caused, namely, combustible gas, heat and oxygen. Therefore, generally USES is added in the sheath material containing halogen halide and metal oxide, from the perspective of flame retardant, that's very good, but, because of the halide is contained in these materials, in a lot of smoke and released when halogenated body, so, the low visibility when fire, bring a lot of personnel evacuation and fire obstruction, whereas people more for functioning suffocated to death.
4×36.0、5×36.0。注释：①另有更大额定电压450/750V、600/1000VRVV电缆线。②另有更多芯线颜色。③另有其他专用场所使用RVV电缆线产品（耐高低温、耐腐蚀、耐切削等性能）。④CCC目录外产品型号为RVV，无CCC认证。
隔离开关的作用隔离开关在大中型电厂的电力系统的应用中，主要作用就是将电源进行隔离、对倒闸进行操作，拉、合无电流或微小电流的电路等方面，有着重大的影响。在对电厂的整体电力系统中的大型电气设备进行检修和日常养护时，就必须利用隔离开关的隔离电源功能，将需要检修的电气设备和带电的电网电源进行分离，形成技术人员明显可见的断开点，能够在技术人员进行定期检修和日常养护的过程中，保证工作人员的人身安全，降低闪络等情况对机器设备的损害，以及出现紧急情况的时候隔离电源，减小损失程度。
