Want to learn more? Check out our electrical cable most frequently asked questions.

What are the application scenarios of copper core PVC insulated overhead cables?

Copper core PVC insulated overhead cables are widely used in low-voltage and medium-voltage overhead power transmission, especially suitable for urban power distribution systems, rural power lines, photovoltaic power systems and street lighting systems. It is also used in building power systems, industrial power distribution and traffic lighting systems, and can provide long-term stable power supply under severe weather conditions.

How can copper core PVC insulated overhead cables ensure long-term weather resistance and durability?

The PVC insulation layer of copper core PVC insulated overhead cables has excellent resistance to UV, high temperature and chemical corrosion. PVC materials can still maintain excellent physical and electrical properties under long-term exposure to solar UV, wind and rain and chemical erosion. In addition, the high conductivity and oxidation resistance of copper conductors further improve the stability and durability of the cable.

What is the maximum operating temperature and use environment of this cable?

The temperature range of copper core PVC insulated overhead cables is typically **-20°C to +70°C**. It is suitable for both hot and cold environments and can work normally in various extreme weather conditions, including high temperature, severe cold, rain, snow and stormy weather. PVC insulation materials perform well in these temperature ranges, ensuring long-term and stable operation of the cable.

How high a voltage can a copper core PVC insulated overhead cable withstand?

The rated voltage of a copper core PVC insulated overhead cable is usually 0.6/1kV, which is suitable for low-voltage and medium-voltage power transmission systems. This cable is widely used in medium and low-voltage power systems such as overhead power lines and photovoltaic power access to ensure safe and reliable power transmission.

What are the advantages of copper core PVC insulated overhead cables compared with aluminum core cables?

Copper core cables have significantly higher conductivity than aluminum core cables. Copper has a lower resistivity than aluminum, so copper core cables have stronger conductivity, can reduce energy loss at the same current, and have higher transmission efficiency. In addition, copper conductors are also more resistant to oxidation than aluminum conductors, which makes copper core cables have a longer service life in long-term use.

What are the installation requirements for copper core PVC insulated overhead cables?

The installation of copper core PVC insulated overhead cable is very simple and convenient, with good flexibility, suitable for wiring in complex environments. It can be laid overhead without additional protective pipes. During installation, ensure that the support points and spacing of the cables meet relevant specifications to avoid damage to the cables due to excessive load. For long-term operation, it is recommended to regularly check whether the cables have signs of damage or aging to ensure the safety and stability of the power system.
