Introduction to Five Core Cable
definition
A five core cable consists of five insulated core wires, which are wrapped in plastic sheaths or steel armor with plastic sheaths.

Including five, all of which are equippedinsulating layerThe core conductors are equipped with an outer protective layer outside each core conductor. One core conductor has a structure with a circular, circular, or flat cross-section, while the other four core conductors have a structure with a corrugated cross-section. The outer edge of the corrugated cross-section is a circular arc and the inner edge is a straight line. The four corrugated core conductors are distributed around the circular cross-section of the core conductors in a manner where the inner edge faces inward, and there is a filling between each core conductorfiller.
Five core cables are mainly used forLow voltage distribution system、construction site、Industrial Automationandcommunication systemIn other fields, it can enhance electrical safety and anti-interference performance due to its inclusion of three phase wires, one neutral wire, and one grounding wire.
Low voltage distribution system
Five core cables are suitable forthree-phase four-wire systemThe power supply system consists of three phase wires (L1, L2, L3), one neutral wire (N), and one protective grounding wire (PE). The neutral line is led out from the neutral point of the transformer and grounded, with a voltage of 380/220V, which can meet the electricity needs of household and industrial equipment.
Temporary electricity supply for construction sites
In construction sites, five core cables are used for temporary power distribution systems to ensure safe power supply for construction equipment and lighting. Its independent PE wire can effectively prevent leakage accidents, which complies withTN-S grounding systemrequirement
Industrial Automation and Equipment Control
Five core cables are widely used in industrial equipmentmotor windingandMining equipmentProvide stable power transmission and signal control. Its multi-core structure andShielding designCan reduce electromagnetic interference, suitable forPLC、DCS control systemWaiting for the scene.
Communication and Precision Instruments
