Development trend of mining cable technology

As we all know, the quality of a product is good or bad, its first characteristic is reflected in the appearance of the product quality. Any product or semi-finished product, in the production process must pay attention to the appearance, strict control. And check. The sheath of the sheath line is the appearance of the cable, so the appearance needs to be round and smooth, uniform luster, no eccentricity (not exceeding the prescribed deviation), no mechanical damage, squashed, no visible debris, bubbles, bubbles, obvious particles, bamboo section shape, twisted shape, etc. In addition to meeting the above quality requirements, the thickness of the sheath also has a certain impact on the quality of the internal cable.

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.

Rvv sheath line is an important part of our wire and cable. So it's not that Rvv sheath wires are not better than THHN wires and vice versa. What are the differences between the two, the two sheath lines are suitable for different applications, what are the differences between them?

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.

For building engineers, wiring is also a top priority, because the wiring can be better used wire more durable, some people just do not understand this measure, the wire procurement back to lay the use of random, then we will understand the wiring knowledge!

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.

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.

The whole process of PV cable management is important for the setup of any solar system. Whether it is the installation of a large solar power station or a solar system in an individual home, a clean PV cable layout is a win-win for both parties.

The PV cable itself is essential to getting your business up and running, so proper maintenance should always be considered. Let's take a look at some of the reasons why it's important to manage photovoltaic cables well.
