High voltage wire with bare conductor is safe

Number of visits: Date:11/7/2015 09:32:08
No insulated or corticose wire is called as bare conductor. Therefore, this kind of wire has the characteristics of fast heat dissipation, light weight and low cost. It is widely used in high voltage transmission line. Also used for the electrical wiring below the safe voltage.
 
 
Why do use bare wire in the high-voltage? Is it safe? 
1 Household wire height is low, easy to contact with people; and high tension line is generally set up at high altitude, not easy to contact. so bare wire is not dangerous.
 
2. Household electrical voltage is generally 220 volts, is low, the insulation layer will not bring too much negative impact; and the voltage flowing through the high voltage line  is very high, current is large, easy to heat, burned insulation skin, and even the breakdown insulation skin.
 
3. general household electrical wire is short; and the high voltage line is very long, the bare wire can reduce the gravity.
 
Under high pressure, some insulated material, such as rubber, plastic, dry wood and so on, will become a conductor, can not play insulation. If you still use insulation skin in the high pressure wire, it spends much more money, waste of money and things.
High voltage wire surface does not cover the skin, it is suspended in the high tower, it may be due to contact with the tower and leakage. In order to prevent this phenomenon, high voltage wires are always hanging in a long string of insulation good insulator, make the high tension line and tower insulation.
 
So using bare conductor in the high voltage is safe. Please rest assured to buy and use. Henan Jiapu cable group is the professional wire & cable manufacturer in China, we not only supply bare conductor, but also can produce aerial bundled cable, power cable, building cable, etc. We can also produce various of specification cables according to requirements of customers.
