We should pay attention to the models and specifications (conductor cross section) of electrical wire and cable when we select electrical wire and cable.
â’ˆ selection of wire and cable models
Use wire and cable, we should consider the laying conditions and safety.
According to the different purposes, we can choose the power cable, overhead insulated cables, control cables, etc.;
According to the different laying conditions, we may make use of ordinary plastic insulated cables, steel armored cable, steel wire armored cable, anti-corrosion cable, etc.;
According to security requirements, we can choose not extend to burning cables, fire-retardant cables, halogen-free flame-retardant cables, fire-resistant cables.
â’‰ the choice of electrical wire and cable specifications
To determine the use of wire and cable specifications (conductor cross section), the general should be considered fever, voltage loss, the economic current density, mechanical strength and other selection criteria.
According to experience, low-voltage power lines because of their large load current, so the general conditions of heat press select cross-section, and then checking the voltage loss and mechanical strength; low-voltage lighting wire the voltage level requirements for its high voltage loss can press the conditions to allow Select cross-section, and then checking the conditions and mechanical strength, heat; pairs of high-voltage lines, then press the select current density of economic cross-section, and then checking the conditions of their heat and allow the voltage loss; while high-voltage overhead lines, but also checking its mechanical strength. If the user does not have experience, they should consult the relevant professional units or advice.
