Main characteristics of the mine cable fire with fire temperature in 600 ℃ ~ 8000 ℃, the fire cases, the cable will soon lose insulating ability, thus cause the secondary electrical accidents such as short circuit, causing a greater loss. The wire and cable have greater overload capacity under the specified allowable load flow. In a short circuit, the wire and cable will instantly cause the insulation to melt and ignite the surrounding area.

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。


   6KV及以上电缆接头: ①安装电缆终端头时,必须剥除半导体电屏蔽层,操作时不得损伤绝缘,应避免刀痕凹凸不平的情况,必要时用砂纸磨平;屏蔽端部应平整,并要把石墨层(碳粒)清除干净。
②塑料绝缘电缆端头铜带屏蔽和钢铠必须良好接地,对短路也遵循这项原则,避免三相不平衡运行时钢铠端部产生感应电动势,甚至“打火”及燃烧护套等事故。

Combination cable, control cable, communication cable, coaxial cable of the combined, messenger combination cable SYV75-5 + RVV RVVP + in order to adapt to the needs of high-tech and various kinds of scientific research, and organized scientific and technological personnel and use the unit joint efforts, the combination of a series of cables. The products have compact structure, performance and convenient installation, and are widely used in communication, navigation, electronic countermeasures, early warning, sea training and exploration, and comprehensive cables for various equipment. According to the requirements of the user, multiple lines, power lines, shielding lines, coaxial radio frequency cables, etc. can be combined into a combined cable with total shielding. In addition, our factory has developed a self-supporting combined cable on the basis of syv75-5 +RVV+RVVP cable, and added a self-supporting steel wire to the cable, which greatly enhances the cable tension. Video line syv-75-5, syv-75-3, power supply line RVV, shielding line RVVP supply video line syv-75-5, syv-75-3, power supply line RVV, shielding line RVVP this company solemnly declares: 1. 2. Product tracking service within two years and keep records in the archives for 20 years. 3. Due to product problems, our company will guarantee, refund, replacement and customer requirements.

Low-smoke halogen free power cable single core cable conductor is round, 16mm2 and above can be pressed tightly. If the cross section of multi-core cable core is 35mm2 or below, its core should be round, and the cross section of wire core should be fan-shaped, tile or semi-circular at 50mm2 and above. The fourth core (neutral core) of a four-core cable can be round or fan shaped. The neutral line of five-core cable can be round or tile type 6mm2 or below. It is allowed to be composed of a single conductor. Forming conductors (fan-shaped, tile or semi-circular) shall be pressed tightly.

X电容应用一般两根引脚跨接在零线和火线之间,适用于高频、直流、交流、耦合,跨接脉冲电路中,能够能承受过压冲击,一般与电阻并联使用,目的是起到泄放电荷作用。
(如所示)Y电容作用Y电容用来消除共模干扰。
分别跨接在电力线两线和地之间(L-E,N-E)的电容,一般是成对出现,滤除高次谐波,防止干扰,提高输出电压质量。
基于漏电流的限制,Y电容值不能太大,Y电容通常采用高压瓷片的。
Y电容应用很多隔离式开关电源在初级和次级上加Y电容是为了给次级的共模电流提供一个回路到初级,减少共模电流对输出的影响。
