How Many Years Does The Quality of XSD BVV Wire And Cable Last? How To Extend The Use of Life Cycle?

BVV wire and cable life cycle, such as most copper-core PVC wire design life cycle between 20-30 years, telephone line design life cycle of 8 years, network cable design life cycle within 10 years, but the specific use of life cycle also with the quality of BVV wire and cable and installation environment and other factors. If you want to extend the use of BVV wire and cable life cycle, you should choose high-quality BVV wire and cable, the correct specifications for storage products, and scientific and reasonable laying, installation.

Factors affecting the life cycle of BVV wire and cable use

1, External factors

BVV wire and cable if laid in a strong acidic and alkaline environment, usually leads to the erosion of BVV wire and cable, the thickness of the protective layer due to long-term organic chemical erosion or electrolytic erosion, resulting in the aging of the protective layer, so before laying to consider the impact of this factor in advance to choose the appropriate BVV wire and cable, and regular inspection. At the same time, we should also try to avoid all kinds of bumping, wear and tear and other external factors damage to the protective layer, to avoid the reduction of insulation performance, which ultimately causes cable failure.

2, Climate change environmental factors

BVV wire and cable in the installation of places to try to avoid exposure to the sun or suffer heavy rain and wind, if placed for too long will be subject to harsh environmental aggression, will accelerate the oxidation of the protective jacket, thus reducing the life cycle of BVV wire and cable.

3, Overload dragging factor

BVV wire and cable should not be overloaded dragging, because the current will produce thermal effects, load power will lead to electric conductors hot, there is the charge skin effect and its steel armor eddy current loss, dielectric loss of the insulator layer will also generate additional heat, which will make the BVV wire and cable temperature rise. If long-term overload tug, high temperature will accelerate the corrosion of the insulation layer, so that the insulation layer thermal bulge to damage, and even explosions, fire, etc..

BVV wire and cable in different laying environment considerations:

1. BVV wire and cable laid in the underground pipeline, generally regularly check the degree of dryness and humidity in the trench.

2. BVV wire and cable overhanging use / overhead cable, need to consider the sagging and pressure of the cable, whether the cable is directly exposed to sunlight.

3. If laid in pipes, such as plastic pipes or metal pipes, you need to pay attention to whether the plastic pipes are damaged and the thermal conductivity of metal pipes.

4. In the underground BVV wire and cable laying, considering the size and complexity of the installation space, the installation of cable trench should be regularly drained of dry and wet degree.

5. If BVV wire and cable is installed on the external wall, you need to pay attention to direct sunlight on the wall and human damage, as far as possible, placed in a safe place.

BVV wire and cable precautions for use.

1. It is strictly prohibited to throw down the cable or cable tray with wire and cable from a high place in transportation, especially in the lower temperature is generally about 5C and below, throwing and dropping BVV wire and cable will likely lead to cracking damage to the outer insulation sheath.

2. BVV wire and cable try to avoid the storage of cables in the open air without any packaging measures, cable tray is not allowed to lay flat.

3. When lifting the packaging, it is strictly prohibited to lift more than one tray of cable at the same time. In vehicles, ships and other means of transport, the cable tray should be fixed to prevent collision or overturning each other to prevent mechanical damage to the cable.

4. BVV wire and cable is strictly prohibited with acid, alkali and mineral oil contact, to be stored in isolation with these corrosive substances, storage BVV wire and cable storage room shall not have corrosive harmful gases.

5. cable during storage, should be regularly rolling BVV wire and cable, once every three months in summer, other seasons can be extended as appropriate. In the rolling, will be stored down the side of the tray rolled over towards the top, so as to avoid the bottom surface of the moisture rot. Storage should often pay attention to the cable head is intact.

The above is to extend the use of BVV wire and cable life cycle needs to pay attention to matters related to, I hope it can help you! We recommend to continue to pay attention toXSD Cable, to learn more information.
