What is the role of the power cables? - People's Cable Group

Power cables has been invented for more than a hundred years, and it has been more and more widely used as the times progress. The copper conductor power cable nowadays is mainly used for underground burying, because it can resist high-strength compression on the ground and has a high degree of corrosion resistance. In the construction sites of many major projects, insulated power cable is an indispensable role.

What role does power cable play in the domestic market?

Power cable is a large class of electrical products used in the fields of power transmission and distribution, power transmission, sound, text, image, and other information dissemination and lighting.

What's more, protected power cable is an indispensable basic equipment for the manufacture of various motors, electrical appliances, and meters. It is also a necessary basic product for power infrastructure construction, new smart grids, and new energy industries.

The power cable industry occupies a large part of the output value of the domestic electrical industry, and is the second largest industry in our country after the automobile industry. Now, the output value of domestic power cable has surpassed other countries, becoming the world's first.

The huge production capacity formed by our power cable enterprise has impressed the world. With the continuous expansion of the domestic power industry, data communication industry, urban rail transit industry, automobile industry and other industries, the demand for power cable will also grow rapidly, and the power cable market has huge development potential in the future.

How is the structure of the power cable designed?

Power cable is a cable used to transmit and distribute electrical energy. It is often used in urban underground power grids, power station outlet lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across the river.

A power cable is a wire core made by twisting one or several wires, wrapped with a corresponding insulating layer, and covered with a sealed metal or plastic protective layer. This structure can protect the core from external damage.

• Core

The core is the conductive part of the power cable, used to convey power, and is the “core” section.

• Insulation layer

The insulating layer can electrically isolate the wire core from the outside world or other ones to ensure electric energy transmission. It is an indispensable part of the power cable structure.

• Shield layer

Power cables of 15 KV and above generally have conductor shielding layer and insulating shielding layer.

• Protective layer

The function of the protective layer is to protect the power cable from the intrusion of external impurities and moisture, and to prevent the power cable from being directly damaged by external force.

What are the advantages of power cable?

There are basically two modern transmission and distribution lines, overhead power lines and power cable lines. In places with dense urban residents or special occasions, for safety reasons, power cables are basically used, which has high practicability and safety performance.

Power cable occupies less land, because it is generally buried in the soil or indoors, in trenches, tunnels, and the insulation distance between the lines is small, so there is no need for towers. The power cable laid underground does not occupy ground space, and the same underground passage can accommodate multiple circuits.

Power cable has high reliability, natural weather conditions (such as lightning, wind and rain, salt spray, pollution, etc.) and the surrounding environment have little influence on the cable, which ensures stable transmission performance and high reliability.

zhuhaicable supply professional and honest service.

Power cables have favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables. Its maintenance workload is less, so the operation and maintenance costs are relatively small.

Although insulated power cable has many advantages, it has disadvantages such as high cost and difficulty in troubleshooting and complicated cable joint technology.

Therefore, the person in charge of the project should weigh the pros and cons in the selection. You can give the choice of copper conductor power cable to People's Cable Group Co., Ltd., as a professional aluminum power cable manufacturer, we will provide comprehensive services and support to help you play its true value, reduce costs for the project, and in the long-term increase income.

Since you quoted the main reason most in the ‘anti power cord’ group think power cords couldn’t possibly be relevant I’m assuming you’ve read the reasons why the last meter can mean something. Hope you’re not trolling as this has been argued for ‘a million years’ and always ends up the same. You can Google it and literally spend days reading what’s already out there and then if you still have questions then I don’t know what else to say as there’s no definitive consensus. You either believe one or the other.

No, it’s the first meter from the Amp. That’s where interference (RFI, EMI, groundloops, etc.) is at the greatest. The weakest link in the power delivery will likely have the most influence at the Amp. Both in the (instantaneous and average) current available and in the noise transmitted or received (etc.)

Try one, if you don’t hear a difference then it doesn’t matter to you.

Same question here…

I just bought a used P10 (which BTW made an immediate and noticeable improvement to the sound of my system) so I’m assuming that the power cable going to the regenerator is not as important as those going from it to the other components. I have good cables for those connections but the current power cable from the wall to the P10 is not rated for 15amps and I have a dedicated 20amp line at the wall. Since it’s an 8ft. run, my plan is to make my own cable since the expense if a 8ft. shielded 20amp cable would be too much.

Is my assumption correct?

I find that a Pangea AC9 SE MK2 made a pretty good improvement over the stock cable to my P12. Much fuller and clearer sounding. You can get a 3 meter for about $375. The better the cord to your re-generator, the better the sound. Cords after the re-generator also makes considerable improvement in SQ.
The good thing is you can try it and if you dob’t like it, return it and get your money back.

Power cables just add a flavour to the sound, person can spend megabucks on one and it will sound just “different”, one meter is enough to make the difference on resolving system, but whether better or worse depends so much on individual system, and components, and audio sources and recordings themselves, room setup, temp and humidity, and what not. I don’t think it is possible to get it right for every content. It is worth making your own cables to get the sound you like, and a lot cheaper too!

Ronen as in the world of high performance cars : Porsche…Ferrari, Lamborghini,
Mercedes AMG Hammer…or BMW M series…Corvette …Shelby Mustangs…

All fast all competent…more than likely you can’t go wrong…

Just research who gives you the best values perhaps even a home audition
make a choice and jump in…

You are otherwise overthinking this

Shalom friend

I am someone who can hardly tell the difference on different speaker cables & IC, and I do own a few half-decent ones. But every time I upgraded the power cables, the improvement is immediate and obvious. Either my home electricity is bad or my ears are more sensitive to the benefits that PC can bring. It’s puzzling but I am digging it.

One simple way to “tweak” the sound a little is to try reverse polarity of power cables. Transformers don’t care about the polarity, therefore manufacturers connect them in random ways. However, there may be quite dramatic changes in the way system sounds. Something to do with live wire hitting outer or inner windings first. On my system in one configuration sounds thin and centered, while in reversed, more spacious and 3D. In countries where power plug can be inserted either way, this can be quite important to get right.
