Deep analysis of photovoltaic cable heating causes and consequences

When the photovoltaic cable in the operation process through a certain load current, will produce a certain amount of heat, with the increase of the cable load current, the cable surface temperature will be gradually higher, if not treated in time, the consequences can be imagined, such as PVC cable, to the core temperature of 70 degrees as the upper limit, the surface temperature will be 5-10 degrees lower, therefore, The surface temperature of photovoltaic cable is basically safe below 60 degrees. From the point of view of power maintenance, the lower the temperature, the better.

How to quickly identify whether the workmanship of high temperature resistant THHN cable is inferior

For all people, safe use of electricity has been very important, high temperature resistant THHN cable has been acting as the cable in the construction industry, if the poor quality of high temperature resistant THHN cable is easy to bring trouble to our life, threatening our safety. Therefore, when choosing high temperature resistant THHN cable, we must polish our eyes and avoid choosing inferior high temperature resistant THHN cable. Because many customers do not know how to check the specific material of high temperature resistant THHN cable, and can not spend a lot of time to detect whether it is poor quality, how to quickly identify whether it is poor quality high temperature resistant THHN cable? There are several ways to do this.

Why use low-smoke halogen-free photovoltaic cable? What are the advantages of using low-smoke halogen-free photovoltaic cable insulators?

In the solar industry, an increasing demand for low-smoke halogen-free photovoltaic cables has been seen. The main concern is the safety of personnel and electronic circuits during a fire. Environmental protection and local and international safety requirements and norms have also increased the demand for low-smoke halogen-free power generation cables. This type of photovoltaic cable is mainly due to the increased awareness of the negative effects of halogen exposure to flame, which led to the design of this sheath type.

What is the sheath line, two minutes can understand the difference between ordinary wire and cable and sheath line?

The sheathed wire is generally two or three conductors of parallel wire with insulated wire. They are more commonly used household wires. Special material selection and design make them more secure in terms of safety, and in the process of home decoration, with the help of this sheath line, but also can achieve a good appearance, safe and convenient use of the effect.
