本厂生产的射频电缆的结构是多种多样的,可以根据不同的方式和型式来分类。射频电缆按结构分类(1)同轴射频电缆同轴射频电缆是最常用的结构型式。由于其内外导体处于同心位置,电磁能量局限在内外导体之间的介质内传播,因此具有衰减小,屏蔽性能高,使用频带宽及性能稳定等显著优点。
6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible.

从另一方面看,同步方式要求进行信息传输的双方必须用同一个时钟进行协调,正是这个时钟确定了同步串行传输过程中每一个信息位的位置。这样一来,如果采用同步方式,那么,在传输数据的同时,还必须传输时钟信号。而在异步方式下,接收方的时钟频率和发送方的时钟频率不必完全一样,而只要比较相近,即不超过一定的允许范围就行了。在数据传输中,较为广泛采用的是异步通信,异步通信的标准数据格式如所示。异步通信数据格式从所列格式可以看出,异步通信的特点是一个字符一个字符地传输,并且每个字符的传送总是以起始位开始,以停止位结束,字符之间没有固定的时间间隔要求。
Armoured oil filled telecommunication 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.
20世纪30年代中后期始有标志飞行场地或跑道边界的灯具。1953年以后,大型快速的涡轮螺旋桨飞机和喷气式飞机相继问世,驾驶员需要在更远的地方发现跑道,航空运量的不断增长也对飞行安全和航班正常提出了更高的要求。
