Power cables
Power cables are divided into low-voltage cables,medium-voltage cables,high-voltage cables,etc.It can be divided into plastic insulated cable,rubber insulated cable, mineral insulated cable, etc.
Control cable
The control cable is similar to the power cable in that it has only copper core and no aluminum core. The conductor section is small and the number of cores is large, such as 24*1.5, 30*2.5 flat cables,Copper core cable,Armored cable,high voltage power cable,3 core Cables Henan New Electric Power Co.,Ltd. , https://www.newelectricpower.com
The most feared thing about the headphones is that the wires are wrapped together, and Pugz also has some protection against this. Pugz uses a magnetic lock design. You can hang it directly around your neck when you don't listen. Just use it when you want to use it. All right.
Although sound quality is not our expectation for this type of headphones, Pugz seems to be worth mentioning in this regard. Pugz frequency range 8Hz – 28 KHz, full of bass. It uses aptX technology to reduce the size of audio files to ensure Bluetooth Can be transmitted smoothly.
Pugz is priced at $199, which is acceptable for such a convenient and stylish headset. 
Power cables are cable products used to transmit and distribute high-power electric energy in the trunk line of the power system,including power cables with various voltage grades and insulation of 1-330 KV and above.
It is applicable to single machine control or unit equipment control of power stations, substations, mines, petrochemical enterprises, etc. with AC rated voltage of 450/750V and below. In order to improve the ability of control signal cable to prevent internal and external interference, shielding layer is mainly adopted.
Empty insulated wire
We are also very common in overhead power lines. Its characteristic is that there is no protective sheath. Its electrical conductors are not only aluminum, but also copper electrical conductors (JKYJ, JKV) and aluminum alloy profiles (JKLHYJ). Now it also has overhead power lines (JKLGY). It is not only single-core. Generally, it is single-core. However, it can also generate beams from two electrical conductors. The rated voltage of overhead power lines is 35KV and below, not 1KV and 10KV.
With the development of technology, the trend of technology equipment is getting smaller and smaller, so there are a lot of "the smallest earphones in history" on the market, and everyone is a little bored. The Pugz Bluetooth headset also says that it is the world's smallest, but it has also been added in the front. "Available mobile phone charging". Pugz headphones are really different. If it is, you can hardly worry about the headset being out of power. In the middle of the headset cable is a special Squicle magnetic connector, connect it to your phone or other device to start charging, completely Does not affect listening to songs. Ordinary mobile phone 3% of the power is enough 4, 5 hours of listening time, very affordable.
