There are many types of wires and cables. When purchasing cables according to their own needs, they should generally pay attention to the selection of wire and cable models and specifications (conductor cross-section). 1. to consider the use, laying conditions and safety. For example: according to the different uses, can choose power cable, overhead insulated cable, control cable, etc.; according to the different laying conditions, can choose the general plastic insulated cable, steel tape armored cable, steel wire armored cable, anti-corrosion cable, etc.; according to the safety requirements, can choose non-flame retardant cable, flame retardant cable, halogen-free flame retardant cable, fire-resistant cable. 2. determine the use of wire and cable specifications (conductor section), the general should be considered.

How to choose the right wire and cable according to your needs

1. to consider the use, laying conditions and safety. For example: according to the different uses, can choose power cable, overhead insulated cable, control cable, etc.; according to the different laying conditions, can choose the general plastic insulated cable, steel tape armored cable, steel wire armored cable, anti-corrosion cable, etc.; according to the safety requirements, can choose non-flame retardant cable, flame retardant cable, halogen-free flame retardant cable, fire-resistant cable.

2. determine the use of wire and cable specifications (conductor section), generally should consider the heat, voltage loss, economic current density, mechanical strength and other selection conditions. According to experience, low-voltage power lines generally select cross-section according to heating conditions because of their large load current, and then check their voltage loss and mechanical strength. Low-voltage lighting lines can first select cross-section according to the allowable voltage loss conditions and check the heating conditions and mechanical strength because of their high requirements for voltage level. For high-voltage lines, the cross-section is first selected according to the economic current density, then check its heating conditions and allowable voltage loss; and high-voltage overhead lines, but also check its mechanical strength. If the user has no experience, the relevant professional unit or person should be consulted.
