Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the direct buried depth of 1-35kv cable is less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. ? 6KV and above cable connector:? When installing the terminal head of the cable, the semiconductor electrical shielding layer must be stripped off. During operation, the insulation shall not be damaged. The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. ? The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic re for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent water and other corrosive materials from corroding, in order to prevent the water tree caused by the aging of the insulation layer and breakdown. Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. ? Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.

Identification and length marking: there is a sexual identification mark on the cable appearance, and the marking interval is not more than 1m.

主要用于存储程序中的变量。在单芯片单片机中（*1），常常用SRAM作为内部RAM。SRAM允许高速访问，内部结构太复杂，很难实现高密度集成，不适合用作大容量内存。除SRAM外，DRAM也是常见的RAM。DRAM的结构比较容易实现高密度集成，比SRAM的容量大。将高速逻辑电路和DRAM安装于同一个晶片上较为困难，一般在单芯片单片机中很少使用，基本上都是用作外围电路。（*1）单芯片单片机是指：将CPU，ROM，RAM，振荡电路，定时器和串行I/F等集成于一个LSI的微处理器。
