选用电线电缆时,要考虑用途,敷设条件及安全性;例如:
When choosing wires and cables, consideration should be given to their use, laying conditions and safety.
根据用途的不同,可选用电力电缆、架空绝缘电缆、控制电缆等;
According to different uses, power cables, overhead insulated cables and control cables can be selected.
根据敷设条件的不同,可选用一般塑料绝缘电缆、橡胶绝缘电缆、钢带铠装电缆、钢丝铠装电缆、防腐电缆等;
According to different laying conditions, general plastic insulated cables, rubber insulated cables, steel belt armoured cables, steel wire armoured cables, anti-corrosion cables can be selected.
根据安全性要求,可选用阻燃电缆、无卤阻燃电缆、耐火电缆等。
According to the safety requirements, flame-retardant cables, halogen-free flame-retardant cables and fire-resistant cables can be selected.
⒉电线电缆规格的选择
_Selection of wire and cable specifications
确定电线电缆的使用规格(导体截面)时,一般应考虑发热,电压损失,经济电流密度,机械强度等选择条件。
When determining the specifications of wires and cables (conductor cross section), the selection conditions such as heating, voltage loss, economic current density and mechanical strength should generally be considered.
