1. Bare conductor type selection
Selection of bare conductor, consider the use, laying conditions, and safety.
For example, according to different purposes, the choice of power cables, overhead insulated cables, and control cables.
Depending on the laying conditions, the choice of general plastic insulated cables, steel armored cable, steel wire armored cable, bare conductor, and other anti-corrosion.
According to security requirements, you can choose retardant cables, fire-retardant cables, flame-retardant cables, and fire-resistant cables.
2. Bare conductor size selection
To determine the use of bare conductor specifications (conductor cross-section), the general should consider heat, voltage loss, economic current density, mechanical strength, etc. selection criteria.
According to experience, low-voltage power lines because of the load current is large, it is generally to press the heating conditions are selected cross-section, and then checking the voltage loss and mechanical strength, low voltage lighting line because of its high level requirements, press the allowable voltage loss condition Select profile, then checking fever conditions and mechanical strength, high-voltage lines, then press the economic current density select section, and then checking their condition and allow the voltage loss fever, and high voltage overhead lines, but also checking its mechanical strength. If the user does not have experience, you should consult the relevant specialized units or persons.
