   2、采用实芯聚烯烃、泡沫聚烯烃或泡沫实芯皮聚烯烃绝缘。 3、线对:由a、b两根不同颜色的绝缘线芯绞合成线对。 4、缆芯结构:绞合线对组成12、13子单位,25对基本单位,50对、100对和200对超单位。

在此基础上,如果有某一个房间非常小,我们可以将它合并到相邻房间内。比如刚才那个户型,如果餐厅特别小,我们就可以把餐厅合并到相邻的客厅里——合并后只需要6个插座回路。注意:卫生间无论多小,都必须是独立回路,不能与其它房间合并。每个功率超过3000W的电器使用一个回路,每两个空调挂机使用一个回路——它们统称为大功率插座回路。三室两厅,需要3个空调挂机(2个回路)、1个空调柜机(1个回路)和1个电热水器(1个回路)。

Armoured communication cable armoring cable type: HYA53, HYAT53, HYA23 HYAT23, HYV22, HYA22 (rat, buried) armoring 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 designed and vulnerable to erosion area 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. 5. The marking contents of armored communication cables include: wire diameter, number of wire pairs, cable model, length, manufacturer name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical re of the basic cable. 6. Cable length: mechanically protected cable is made according to the length of the corresponding basic cable

同步字符起联络作用,用它来通知接收方开始接收数据。在同步通信中,发送方和接收方要保持完全的同步,这意味着发送方和接收方应使用同一时钟脉冲。在近距离通信时,可以在传输线中设置一根时钟信号线。在远距离通信时,可以在数据流中提取出同步信号,使接收方得到与发送方完全相同的接收时钟信号。由于同步通信方式不需要在每个数据字符中加起始位、停止位和奇偶校验位,只需要在数据块(往往很长)之前加一两个同步字符,所以传输效率高,但是对硬件的要求较高,一般用于高速通信。

  在改进耐火层制造工艺和增加耐火层等方法的基础上又研制了A类耐火电缆,它能够在950℃~1000℃的火焰中和额定电压下耐受燃烧至少90min而电缆不被击穿(即3A保险丝不熔断)。A类耐火电缆的耐火性能优于B类。

   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。

  MHYBV型弯曲半径不小于电缆直径的10倍。MHYVP型弯曲半径不小于电缆直径的10倍。MHY32型弯曲半径不小于电缆直径的15倍。双屏蔽双绞线电缆-RVSPVP。国标生产严把质量关;户外电话线(带油膏填充和铠装-防紫外线和防水-可埋在地下)HYAT53通信电缆填充石油膏系列:主要用于对多导体电线电缆缆芯的空隙进行填充,起防潮和绝缘作用。
