如采用75-9同轴电缆时,摄像机和监视器间的距离在500m以内可不加电缆补偿器。HYA通信电缆,HYA22HYA23铠装通信电缆用途:实心绝缘填充型电缆适用于本地电信网的城市与乡镇电信线路,也适用于接入公用网的专用网线路。
The shielding layer can not only restrain the electromagnetic wave from transmitting, but also act as a channel for short-circuit current, which can protect the neutral core. 6/10 kv dedicated cable frequency conversion motor, considering the cables, external force is often in the process of using radial outside the cable shielding layer increased galvanized steel tape armoured layer (between shielding layer and steel tape armoured layer of sleeve).

1. Wire: annealed bare copper wire with a diameter of 0. 30, 0. 42, 0. 52, 0. 60, 0. 70, 0. 80, 0. 90 (mm). 2. Insulation material: high density polypropylene or polypropylene, color of the insulation line according to the whole chromatogram. 3. Pair of insulated wires: twisted two insulated wires of different colors into pairs according to different pitch, and used the specified chromatographic combination to identify the pairs. 4. Communication cable core structure: take 1 pair as the basic unit, more than 25 pairs of cables are combined according to units, and each unit is wired with the unit of specified chromatogram in order to identify different units. 100 pairs of cables with more than one pair of cables plus 1% of the reserve pair, but not more than 6 pairs. The gap in the core is filled with oil paste. 5. Core wrap belt: wrap with polyester film tape. 6. Shielding: copper wire shielding or metal strip with or without striping, which is longitudinal wrapped outside the core of communication cable. 7. Sheath: blue low-density polymer. Communication cables with double sheaths can also be provided.
为了大家有一个好的学习方法,能在快短的时间内学会掌握plc的应用,特此为初学PLC的同学编写了一份学习PLC的流程和方法,教大家如何学习PLC,希望对大家有所帮助,这是某个学员学习时候的一些学习方法及感悟,特此分享给大家。当然,这只是我自己的观点,大家如有什么好的建议,也希望同学们能向我积极提出来,我们共同讨论学习和进步。第一:掌握西门子硬件的结构及各部分的一个功能,熟悉PLC的硬件接线,:开关量输入输出的接线,模拟量输入输出的接线。
注:可根据用户要求生产(ZR)阻燃型、(IA)本安型及耐高温型计算机电缆。YJV-PVLV-PYJLV-P聚氯乙烯(交联聚乙烯)绝缘金属屏蔽聚氯乙烯护套电力电缆。YJLV22-P聚氯乙烯(交联聚乙烯)绝缘金属屏蔽钢带铠装聚氯乙烯护套电力电缆。
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.
Insulation resistance: each conductor and the rest of the grounding wire core, the control cable is more than 10000 m Ω. Km, more than 3000 m Ω HYAT cable. Km.
有的在护套外面还装有外护层。有架空、直埋、管道和水底等多种敷设方式。按结构分为对称、同轴和综合电缆;按功能分为野战和永备电缆(地下、海底电缆)。通信电缆传输频带较宽,通信容量较大,受外界干扰小,但不易检修。

二、产品执行标准:GB/T12706.1-2008三、使用特性:表1使用特性聚氯乙烯绝缘交联聚乙烯绝缘导体高额定温度70℃90℃短路温度(持续长5s)≤160℃≤250℃敷设时环境温度≥0℃(低于0℃时需预热)敷设时允许弯曲半径单芯电缆单芯电缆不小于电缆外径的15倍,多芯电缆不。
