The DC cable is positive and negative poles, and the structure is simple. Direct current cable is fairly straightforward and the power strictly flows in one direction. That means the electrons get pushed in from the power generator, and keep going forward through the wire until it gets to your device, does its work, then continues through the outlet to complete its circuit. These dc power supply cables are designed for connecting photovoltaic power supply systems.
DC power cable is used as low voltage, as most of modern electronics operate at vey low voltages and in some case batteries in small sizes can support the sensors for years like gas and fire detectors. These dc power supply cables can be used indoor & outdoor for flexible and fixed installations with high mechanical strength in extreme weather conditions.
DC cables are used in rectified DC transmission systems, while AC cables are commonly used in industrial frequency (domestic 50 Hz) power systems. The AC cable is a three-phase four-wire or five-wire system, the insulation safety requirements are high, the structure is complex, and the cable cost is more than three times that of the DC cable. Many places you can not run wires for AC, then DC power supply cable is the best solution.

SSI DC power cables are flexible and are resistant to abrasion & moisture. Most household appliances and consumer electronics—cellphones, laptops, microwaves, light bulbs, you name it dc power cable use direct current (DC) electricity. That's why the PTFE Teflon DC Cable of SSI Cables and wires is the best and has the best quality standards in India.
