As for transmission, its transmission capacity is very large. Both the rivers and lakes across the […]

Speaking of wires and cables, we have to mention copper and aluminum in their main materials. The question is, what is the difference between copper core and aluminum core wires and cables? Which is better? Let’s get to know~ There are several ways to distinguish whether the wire core is copper core or aluminum core […]

1、 Greedy for low prices. This is a common misunderstanding of many users and even some enterprises in the exercise of wires and cables. In order to save money and ignore safety, some users choose low-quality wires and cables with low price, no guarantee of quality and great potential accidents. We know that due to […]

The term ACSR stands for “steel cored aluminum conductor”. It is a stranded conductor, including many aluminum conductor layers on the simulated steel wire core. The steel wire core here is a single steel wire depending on the size. These can be used for different zinc coatings, such as grade A, B and C, to […]
