Physical characteristics of aluminum alloy cables

The advantage of aluminum alloy cable over ordinary cables is that under the same volume, the actual weight of aluminum alloy is about one-third of copper. According to this calculation, under the premise of meeting the same electrical conductivity, the length of the aluminum alloy cable with the same weight is twice that of the … Read more

Talking about the advantages of prefabricated branch cables

With the strong growth of my country’s national economy, the speed of various infrastructure, capital construction, and real estate development has accelerated. It is a historical necessity to use mining aerial bundled cables(abc) as the main supply, distribution, and trunk lines in various buildings and facilities. Therefore, construction units, design units, and construction units are … Read more

Basic cable performance test

1. Inspection method Routine test: It is an experiment conducted by the manufacturer on all finished cables. Its purpose is to check whether the quality of the product meets the requirements of the technical conditions in order to find accidental defects in the manufacturing process. It is a non-destructive experiment, such as the DC resistance … Read more

Selection of cables in normal operation of the wiring system

The entry test of the wiring system is mainly divided into aerial bundled cable(abc) astm b230 test, jumper test, module test and external crosstalk test. Module testing is currently mainly used in laboratory technology models due to its complex technology, mainly facing manufacturers of wiring systems, while the other three are common approach testing techniques … Read more

How to distinguish between national standard wires and inferior non-standard wires

Before moving into a new house, everyone will check the house first, but most citizens will focus on the structure of the house, and they rarely care about the wires inside the walls. If the house is compared to a person, then the wires hidden in the walls are the vital “arteries”. The wires for … Read more

The advantages of copper core cable and aluminum core cable are compared

Copper core cables have more advantages than aluminum core cables: 1. Low resistivity: the resistivity of aluminum core aerial bundled cable BS 7870 is about 1.68 times higher than that of copper core cable. 2. Good ductility: the ductility of copper alloy is 20-40%, the ductility of electrical copper is more than 30%, while aluminum … Read more
