How Are Electrical Wires Manufactured

Just how to expand the 12V DC power cable of the CCTV safety video camera?

We are a professional cord manufacturers,our cordless IP cam features a power cord, which is split into 3 meters and also 5 meters according to the type of cam. Typically, it can meet the use of many scenes, yet sometimes where it is inconvenient to provide power nearby; if you want to mount the place is much from the power supply location, and the original power cable is not long enough, what should I do? The initial power supply will have a certain voltage redundancy. On this basis, we can utilize the DC power expansion cable to expand the power supply range.


What is a DC power expansion wire?

A DC power expansion cord is an electrical wire that connects a DC device as well as a DC source of power. It is a wire that transfers power; the way of transmission is the point-to-point transmission. DC power extension cable is likewise called a DC power expansion cable.


DC power extension wire applications

The DC power expansion cable television is generally utilized to supply power in low-voltage, low-current applications such as CCTV Cameras, routers, projectors, monitors, LED lamps, photovoltaic panels, Notebooks, etc. They are optimal for a scenario where the power cable is too brief for issues.

Exactly how to pick the suitable DC power extension cable?

When selecting a DC expansion wire, we require to focus on the adhering to factors:

1.Power-user interface size

The original power supply adopts a conventional DC5.5 mm * 2.1 mm man adapter. The adapter of the power adapter cable requires to be a DC5.5 mm * 2.1 mm women’s adapter on one side and a DC5.5 mm * 2.1 mm male connector beyond to make sure that it can be matched typically.


Keep in mind: A couple of brand cam power cord is 5 meters long, and also, the adapter is a Mini interface, not a 2.1 mm.

2.The product of the wire

The original power supply is constructed from pure oxygen-free copper material, with reduced resistance and reduced loss; if an external adapter wire is connected, added loss and voltage decline will happen. If the voltage drop is expensive, there will want power, as well as the video camera, will not have the ability to provide power usually.


Consequently, choosing a material with a smaller electrical cable resistance is required. The resistance worth (voltage decline) representing our typical cord is as follows:

The material of the wire

wdt_ID Power Cable Material 100m Resistance (Ω)
1 diameter 1mm copper wire 3,10
2 diameter 1mm copper clad aluminum 5,60
3 diameter 0.5mm copper clad aluminum 19,10
4 diameter 0.5mm copper clad silver 12,00
5 diameter 0.5mm copper wire 8,40
6 diameter<0.4mm copper clad aluminum 46,00
7 diameter<0.4mm copper clad metal 144,00
8 diameter 1mm copper clad aluminum 5,60
9 diameter 0.52mm copper wire 8,30
Power Cable Material 100m Resistance (Ω)

Therefore, we generally advise utilizing 0.5 mm oxygen-free copper or far better cable to lower line loss as high as possible.

3.Size of cord

The original power supply wire is generally three meters/5 meters in size, and also the common DC power expansion cable televisions are 1/3/5/ 10 meters in length. You can pick extension cables of various lengths for power supply according to the demands of the actual scene.

( 1) Usual wire examination

We make use of 0.5 mm oxygen-free copper expansion cords of various sizes for screening, and also the test results are as complies with:

Common wire test

wdt_ID Original Power Cord Cable Length Total Length Power
1 9V 0.6A (3m) 1m 4m Y
2 3m 6m Y
3 5m 8m Y
4 10m 13m Y
Original Power Cord Cable Length Total Length Power

According to the actual dimension, the mainstream DC extension wires on the marketplace can be used with our original power adapter to supply power to the cam to extend the power supply cable.

( 2) Maximum prolonged distance test

We make use of a 20 meters 0.5 sq.mm2 oxygen-free copper expansion cable with the original power supply to power the cam, and the camera can generally function during the day and also at night.
