　　从那时起评估和寻找PVC料的替代物遂成为人们争论的焦点。早在1986年欧洲首先发现燃烧产物中含有的多溴二苯醚，四溴代双苯并二恶烷及四溴代双苯并呋喃等属于致癌物质。直至2001年英国又接连发现五溴二苯醚，十溴二苯醚在野生猎鹰蛋内的生物积累高出家养猎鹰蛋400倍。

还有一种特殊情况，若电动机的负载较轻(小于额定负载的40%)，则不需较大的负载电流来产生电磁转矩去克服阻力矩，此时定子绕组由三角形接法改为星形接法，由于绕组相电压大大降低，励磁电流明显减少，所以总的定子电流也减小，而电机的功率因数和效率则相应提高。当大马拉小车时，即电机的负载小于额定负载的40%时人为将电机由三角形改为星形，达到节能降耗的目的。以上就是本人的一点经验总结，尤其希望对电工新人有所帮助，共同学习进步。

Flame retardant cables and fireproof cables: the difference between the average person is very easy to confuse the concept of flame retardant cables and fireproof cables, although there are many more flame retardant cable applies to the advantages of chemical enterprise, such as low, low smoke, non-halogen, but in general, fire-resistant cable can replace flame retardant cable, and flame retardant cables can't take place of fire-resistant cable.

Spin cassette XF5-273 communication cable transfer box, adopting advanced technology at home and abroad, in accordance with the international advanced standard production in the eighty s of cable wiring e, for the city, the town of telecommunication network backbone cable and wiring cable transfer. Features: 1. The connection jumper adopts rotary clamp-type connection and is sealed with silica gel on the metal clip, because it is not only reliable and durable, but also easy to operate and repair without stripping. 2. The wiring terminals in the handover box shall be arranged in 25 pairs as a basic unit, consistent with the basic units of the local telephone cables and marked with Numbers on the terminals to facilitate construction and maintenance. 3. The structure, arrangement and installation dimensions of the wiring modules are exactly the same as those of 3M products and can be used for each other. 4. The box body is treated by electrostatic spraying, beautiful and generous, with clear lines, good anti-corrosion and waterproof performance and long service life. Main technical parameters: the environment temperature: - 40 ℃ ~ + 65 ℃ atmospheric pressure: 70 ~ 106 kpa relative humidity: 95% or less is random ends and insulation resistance between terminals and ground > 5 x 104 Μ Ω. When connecting any two ends and any terminals and grounding to 1000V ac, there shall be no breakdown or flying arc in 1min. Contact resistance between wire and terminal < 5 x lO - 3 Ω.

两者之间经过一条通信线路(通常是RS422)联系在一起，使得它们得以共享所有的信息资源。也就是说，PLC中所有供用户使用的软件资源，即数据寄存器、状态寄存器、定时器、计数器等，在GOT中也有完全相同的一套镜像。其中任何一台计算机，无论因何种原因，以何种方式，改变了任何资源中的任何信息，都会在另一台计算机中立即被复制。也可以说，因为两者之间的即时通信，使得两者的信息资源互为镜像。这种既独立又分工的协作关系，使得它们能够出色地完成共同的任务。

This product is suitable for communication lines in urban, suburban and local areas. Conductive core wire adopts soft copper wire with nominal diameter of 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9mm. Twisted into the single wire insulation after the heart type (10, 20) or the unit type twisted into core (30 to and above), each basic unit of the unit with same color, the basic unit of cable tie color arrangement according to the re of the chromatography. On the surface of the cable core, a non-hygroscopic polyester belt or a non-woven cloth belt is used to wrap the cable core and then add the longitudinal package of the moisture-proof metal shield belt. The outer sheath can be made into polyurethane or chlorine sheath. The self-supporting cable is to squeeze the cable core and steel strand parallel to the same "8-character" calabash outer sheath. ?
