Low-voltage cables are generally classified into polyvinyl chloride insulated (plastic) power cables, XLPE insulated power cables, rubber insulated power cables, oil-filled and oil-immersed paper insulated power cables according to their insulation types. General power cables, overhead power cables, mine underground power cables, submarine power cables, anti-(fire) fire-retardant power cables and other types.
Low voltage cable is widely used in voltage 1kV cable system, Low Voltage XLPE Insulated Electric Cable the combination of the combination of simple, convenient and flexible, with all insulated, fully sealed, safe and reliable performance. As it has any characteristics of it? Xiaobian take you to take a look and look at:
1, fully insulated, fully sealed structure. Low Voltage XLPE Insulated Electric Cable Reliable to ensure personal safety.
2, dustproof, fireproof, corrosion-resistant, maintenance-free, can be used for outdoor, can also be soaked in water, suitable for any harsh environment.
3, the combination is extremely flexible, Low Voltage XLPE Insulated Electric Cable up and down the line up to eight, to meet the requirements of a variety of wiring.
4, small closure, compact structure, easy to install, easy to operate.
5, can be short-circuit fault indicator, easy to quickly find the cable fault.
What is the role of low-voltage cable
1, the so-called low-voltage wire is 0.6 / 1KV the following cable (including) for the low-voltage cable, the difference is the tolerance voltage is different, insulation and sheath structure is different; 0.3 / 0.5kv 0.45 / 0.75kv control cable; 0.6 / 1KV Low voltage power cable.
Second, the low-voltage cable above the 3.6 / 6KV, 8.7 / 10KV, 8.7 / 15KV, 21 / 35KV high-voltage power cables, as well as ultra-high voltage 100KV.
Low-voltage cable in people's lives in the production of an important role, that several know in the purchase of low-voltage cable when the power to pay attention to what? In the selection of low-voltage cable, Low Voltage XLPE Insulated Electric Cable the general attention to low-voltage cable models, specifications (conductor cross-section) choice.
⒈ low-voltage cable model choice
When using low-voltage cables, consider the use, laying conditions and safety; for example,
According to the use of different, can choose power cables, overhead insulated cables, control cables, etc .;
According to the different conditions of laying, you can choose the general plastic insulated cables, steel armored cable, wire armored cable, anti - corrosion cable;
According to the safety requirements, can choose non-flame retardant cable, Low Voltage XLPE Insulated Electric Cable flame retardant cable, halogen-free flame retardant cable, fire-resistant cables.
⒉ low voltage cable specifications
Determine the use of low-voltage cable specifications (conductor cross-section), the general should consider the heat, voltage loss, economic current density, mechanical strength and other selection conditions.
According to experience, low-voltage power line because of its large load current, it is generally selected according to the heat conditions of cross-section, and then check the voltage loss and mechanical strength; low-voltage lighting line because of its high voltage level requirements, the first voltage loss conditions Select the cross-section, and then check the heat conditions and mechanical strength; for high-voltage lines, the first by the economic current density selection section, and then check the heat conditions and allow the voltage loss; Low Voltage XLPE Insulated Electric Cable and high-voltage overhead lines, but also check its mechanical strength.
