選擇電力電纜的截面應從哪幾個方面考慮?

選購電氣通信電纜的受力應向哪幾塊層面確定?應確定以下的幾塊層面：　　(1)通信電纜經常性合法經過的做工作直流電壓;　　(2)若果串電時的熱比較穩界定;　　(3)電纜線上的直流電壓降不可超出標準可以工做標準。　　電力電纜在公路運輸裝運流程中應準備甚么?　　(1)在運送搬運全過程中，不要把纜線及纜線盤遭到拉傷，嚴防將纜線盤直接的由汽車上推下，纜線般不會平放運送，平放貯藏。　　(2)運輸物流或會滾動線纜電線盤前，保證質量線纜電線盤經久耐用，線纜電線繞緊、充油線纜電線至各種壓強油廂間的油管接頭應固定的，只能影響，各種壓強油廂應經久耐用，各種壓強提示應適合必須。　　建設電力電線電纜頭時，對上上下下扳彎電力電線電纜芯線有什么規定?　　扳彎線芯時，沒法傷害紙隔熱，芯線的微彎球半徑沒法小于等于線纜線芯的10倍。制成時要尤其是仔細，時應線芯微彎方面飽滿物理受力，不可能非常容易傷害隔熱紙。　　論述塑料件線纜的熱彎曲隔絕法。
