Transportation and storage of wires and cables

It is strictly forbidden to drop cables or cable trays from high places during transportation, especially when the temperature is low (usually about 5 ℃ and below), throwing and dropping cables may cause insulation and sheath cracking.

Summary Report of Shanghai Photovoltaic Exhibition

23rd: Visit and learn about Jiweida's factory company in Shanghai, and have a clearer idea about the product usage scenario and direction, including future market development, and take the State Grid as the customer development direction. 24-25: Participating in Shanghai New International Expo Center, more than 2,800 exhibitors of this exhibition visited 43 industry companies. Through communication, they learned that the operation links of photovoltaic system include: solar panel link bracket, transmission to junction box through photovoltaic cable, connection to inverter and energy storage cabinet, and finally substation. Among them, there are 10 solar panel companies, 4 solar support companies, 7 general contracting companies, 14 wire and cable companies, 3 energy storage battery companies, and 5 other photovoltaic module companies.

Common misunderstandings about wires and cables

Wire and cable is used in all walks of life, so before the purchase of wire and cable, we will understand various parameters and evaluations through the network, but many evaluations on the Internet are not very professional, which often causes users' psychological doubts and worries, and will also be blocked in the purchase. The following Qiaopu cable for you to explain in detail our common understanding of the cable misunderstanding.

Main classification of wire and cable products

The main features of this kind of products are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper aluminum bus bar, electric locomotive line, etc. The processing technology is mainly pressure processing, such as melting, rolling, drawing, stranding/tight stranding, etc. The products are mainly used in suburbs, rural areas, user main lines, switch cabinets, etc.

Discussion on the Difference between National Standard Cable and Non-standard Cable

I think that the cable is cheap and can be guaranteed to be a national standard. Nine times out of ten, it is a side ball. Fool unprofessional users who do not understand the industry. In order to enable the majority of users to more clearly understand the quality standards of cables and wires and self-judgment of the difference between national standards and non-standard. Below we combine the actual situation that engineering users and cable industry often encounter, let everyone do a simple understanding.

Seven requirements for high-quality flexible cables

According to the number of flexible cable cores and the space in the cross area of each core wire, there is a real center filling line in the center of the cable as much as possible (instead of the garbage core wire filling made of some filling materials or waste materials under normal circumstances). This method can effectively protect the stranded wire structure and prevent the stranded wire from drifting to the central area of the cable.

The concept of wire and cable and the distinction between wire and cable

Wire and cable refers to materials used for power, communication and related transmission purposes. There is no strict boundary between "wire" and "cable. Generally, products with a small number of cores, a small product diameter, and a simple structure are called wires, those without insulation are called bare wires, and others are called cables; conductors with larger cross-sectional areas (greater than 6 mm²) are called large wires, and smaller ones (Less than or equal to 6 mm²) is called small wires, and insulated wires are also called cloth wires.
