Class A system - any phase conductor of such A system can be separated from the system within 1min when it comes into contact with ground or ground conductors. B class system, the system includes only the single-phase earth fault short-time running conditions, earth fault time should be no more than 1 h, but in any case, the longest do not exceed 8 h, ground fault total duration of not more than 125 h every year; Class C systems -- systems that do not belong to class A and class B.

Characteristics of inverter cable: 1. Low effective capacitance; 2. Good fire resistance, can be used in dangerous areas

二极管基本的工作状态是导通和截止两种，利用这一特性可以构成限幅电路。所谓限幅电路就是限制电路中某一点的信号幅度大小，让信号幅度大到一定程度时，不让信号的幅度再增大，当信号的幅度没有达到限制的幅度时，限幅电路不工作。利用二极管来完成这一功能的电路称为二极管限幅电路。所示是二极管限幅电路。在电路中，A1是集成电路（一种常用元器件），VT1和VT2是三极管（一种常用元器件），R1和R2是电阻器，VD1～VD6是二极管。

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.

　　（7）低压电缆不应采用铝芯，采区低压电缆严禁采用铝芯。电缆截面的选择电缆截面的选择包括高压电缆截面的选择和低压电缆截面的选择，并以低压电缆截面的选择为主。1.电缆主芯线的选择一般采区低压供电线路都比较长，在运行中电缆流过电流会产生压降而发热。
