一个浅显的道理是，对新电工来说电气运行、检修、电力安全等教育，单次再有声色的安全教育，古人讲究“因材施教”，电力新员工何尝不是？在安全教育的方式方法上，一切僵化、死板的模式都须改正，多一些创新的培训方式、丰富的培训内容未常不可。最重要的应是始终站在新员工的角度，让危险点分析、风险辨识、风险防范、技术培训、岗位练兵等“规定动作”常态化、规范化，让培训具有指导性、针对性和实效性，久久为功、接续长期地开展才有更好的效果，才能更入脑入心，才会有效果。

RS485 bus due to its wiring is simple, stable and reliable and widely used in video surveillance, access control intercom, building alarm and other fields, however, because there are a lot of in the process of 485 bus wiring is not completely accurate concept leads to many problems. Some wrong ideas will now be clarified.

Steel tape armoured mainly as the radial mechanical protection layer of the cable, and it also have additional total shielding effect, especially steel tape armoured and copper wire, copper tape screened, is adopted two different shielding materials, play a complementary role in electromagnetic wave shielding, shielding effect will be better.
6、电缆长度：机械保护型电缆是根据相应基本电缆的标准长度制造1产品名称：矿用电话电缆矿用电话电缆MHYAV（20 30 50 ）X2X0.8 MHYA322执行标准MT818.3、用途:本产品用于井下作电话通信焊线、配线和用户线路。
HB型要通过轴向磁路形成三维磁路，并且定子铁心叠片很厚，磁通要垂直穿过铁心叠片；而RM型步进电机的转子磁路垂直于输出轴平面流通，定子磁路沿硅钢片压延方向形成，故磁路变短，磁阻减小。RM型的转子表面因没有HB型的软磁材料，所以没有磁阻、电感小，适用于高速运行。从上述分析看出，该电机适用于高速、髙输出功率、低振动、低噪音场合。与HB型比较，因磁极数的限制，难以达到高分辨率（微小步距角），所以要依据使用目的加以选择。

Self-supporting full-plastic cable (HYAC) : self-supporting full-plastic cable has two kinds of concentric structure and calabash structure. The commonly used HYAC full-plastic cable is calabash structure. Wire: annealed bare copper wire with diameter of, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9; Color the insulation line according to the full chromatographic standard. A single insulated wire is twisted in pairs at different pitch to minimize crosstalk and a specified chromatographic combination is used to identify pairs of wires. Cable core: the cable core structure is based on 25 pairs of cables. More than 25 pairs of cables are assembled according to the unit. Each unit is wrapped with the unit of specified chromatogram to identify different units. More than 100 pairs of cables plus 1% of the reserve pair. Shielding: the shielding layer is made of corrugated metal tape which is wrapped vertically on the outside of the cable core wrap belt and firmly bonded on both sides. The metal strip of the shielding layer is coated with plastic film to facilitate bonding with the sheath to prevent corrosion of the shielding layer. Protective sleeve: protective sleeve is black low density polyethylene, can use double protective sleeve according to the need.
