HYAT23 armoured communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and vulnerable to erosion area and design of telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter.

HB型步进电机的定子有槽，线圈为集中方式，为达到机械绕线的目的，绝缘构造也加以改进。以图左为例，日本伺服(股份)公司用的槽绝缘插入绕线的定子，绕线如右图所示。该方式如上左图所示，定子铁心厚度为电机厚度的1/2，用裙状绝缘材料插人槽中，铁心槽侧面全部被树脂覆盖,利用绕线机的梭子牵引线机械绕制，线圈一个端点固定在接线柱上，另一端连接固定后从引出线出口引出。用此方法，电机定子与引出线部分可分开生产，便于部件标准化。

HJVV, HJVVP, HPVV communication cable: mainly used for transmitting audio, 150kHZ and below analog signals 2048kbit/s and below digital signals. Under certain conditions, it can also be used to transmit digital signals over 2048kbit/s. Used for short distance signal transmission. WeChat sales department is newly added in our factory. WeChat ID: QQ is not convenient for WeChat contact! HJVV, HJVVP, HPVV communication cable is introduced: used for distribution frame or switch to switch internal connection between the machine at all levels (including rural telephone bureau), such as the beginning of the line and terminal for connection to local telephone cable to the junction box or distribution frame, inner conductor wire diameter (mm) : 0.40, 0.50, 0.60, 0.70, 0.80, 0.90, logarithmic (on) : 5-1000 HPVV low-frequency communication wiring cable wiring cable HPVV ZR - HPVV broadband/product use: It is applicable to the transmission system from the remote optical network unit to the user and the subsystem of the transmission between buildings in the building wiring system. The highest transmission fre are 30MHz and 100MHz respectively.

　　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。为了减少回路间的相互串扰和外部干扰，电缆采用屏蔽结构。

为了进一步理解电路工作原理，在看图分析时可以采用直流等效电路法、交流等效电路法，对电路进行静态、动态分析。直流等效电路法就是在输入信号为零时，各级放大电路在直流电源作用下的工作状态，实际上就是找出直流通路，确定各级电路在静态时的偏置电流和电压。交流等效电路法就是在输入信号不为零时，确定电路的交流信号通路及工作状态。应当注意的是，在采用等效电路法分析是，要根据元器件性质给予特别处理。如电路中含有电容、电感这两种元件时，电容具有“隔直通交”的作用，电感具有“隔交通直”的作用。
