The cross section of the control cable is generally no more than 10 square meters, and the power cable is mainly used to transport power, which is generally large. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section of the general factory is relatively less, you can do and control cable section generally small, generally not more than 10 square, tell from some cable, power cable according to the demand of power grid more generally for 5 core, and control cable transmission control, some more, according to the terms of more than 61 core, but also can produce according to user re

接地引出线要求采用我镀锡编织铜线，和电缆铜带连接时应用铬铁锡焊，不宜用喷灯封焊，以免烧损绝缘。③三相铜带屏蔽应分别与地线相连，注意屏蔽接地线和钢铠接地线应分别引出，相互绝缘，焊接地线的位置应尽量靠下。对电缆端头和中间接头的基本要求：a.导体连接好；b.绝缘可靠，推荐采用辐照交联热收缩型硅橡胶绝缘材料；c.密封良好；d.足够的机械强度，能适应各种运行条件。
Non-combustible mineral insulated cables may be used in oil tank areas, public buildings with important wooden structures, high temperature places, and other situations where fire resistance re are high and installation is acceptable and economic performance is acceptable. When the self-capacity oil filled cable is applied to the public corridor, passenger tunnel, bridge and other situations re fire prevention treatment, it can be buried in sand. Close to the cable trench of high voltage current, voltage transformer and other oil-bearing e, it is advisable to seal the trench cover plate in this section.
信号电缆按护套类型包括塑料护套（PTY03、PTY23）、综合护套（PTYA23、PTYA22）、铝护套（PTYL23、PTYL22）信号电缆；2.信号数字电缆分为塑料护套（SPTYW03、SPTYW23）、综合护套（SPTYWA23）铝护套（SPTYWL23）、内屏蔽（SPTYWP03或SPTYW。

三线制变送器如图三所示，所谓三线制即是电源正端用一根线，信号输出正端用一根线，电源负端和信号负端共用一根线。其供电大多为24V.DC，输出信号有4-20mA.DC，负载电阻为250Ω或许0-10mA.DC，负载电阻为0-1.5KΩ；有的还有mA和mV信号，但负载电阻或输入电阻，因输出电路方式不一样而数值有所不一样。以上三个图中，输入接纳外表的是电流信号，如将电阻RL并联接入时，则接纳的即是电压信号了。
耐火电缆选用根据耐火电缆的具体特性，设计人员在设计选用时应注意以下几个问题：(1)当耐火电缆用于电缆密集的电缆隧道、电缆夹层中，或位于油管、油库附近等易燃场所时，应首先选用A类耐火电缆。除上述情况外且电缆配置数量少时，可采用B类耐火电缆。

Summary: fire-resistant cable refers to the cable which can keep safe running for a certain time under the condition of flame burning. China's national standard GB12666.6 IEC331 (e) will fire test points A, B two levels, A grade flame temperature of 950 ~ 1000 ℃, the duration for fire, 90 min, class B flame temperature of 750 ~ 800 ℃, for fire duration 90 min, during the whole test, the sample should be under the rated voltage value of the product. Fire-resistant cable is widely used in high-rise buildings, subway, underground street, large power stations and the important industrial and mining enterprises and other related to fire security and its lifesaving, for example, fire fighting e and emergency light guide emergency facilities such as power supply circuit and control circuit. Purpose: fireproof cables are widely used in high-rise buildings, subway, underground street, large power stations and the important industrial and mining enterprises and other related to fire security and its lifesaving, for example, fire fighting e and emergency light guide emergency facilities such as power supply circuit and control circuit.
