Cable pulling machine factory strength is very important

 Cable pulling machine manufacturers strength is very important, cable pulling machine manufacturers in the selection of wire and cable, generally pay attention to wire and cable models, specifications (conductor cross-section) of choice. ⒈ select models of wire and cable wire and cable selection, consider the use, laying conditions and safety; Depending on the application, the choice of power cables, overhead insulated cables, control cables; depending on the laying conditions, the choice of general plastic insulation cable, steel armored cable, steel wire armored cable, cable and other preservative; according to security requirements, the choice retardant cables, fire-retardant cables, flame retardant cable, fire-resistant cables. ⒉ wire and cable size selection is determined using standard wire and cable (conductor cross-section), the general should consider heat, voltage loss, economic current density, mechanical strength and other 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. Source cable pulling machine http://www.changxindl.com/.
