How to distinguish steel core aluminum conductor from all aluminum conductor?
Share:
Steel-core aluminum stranded wire and aluminum stranded wire are wires without external insulation, which are commonly known as "bare wires". So how to distinguish steel core aluminum stranded wire from aluminum stranded wire?
1. Distinguish from cross-section color
If the cross-section can clearly see that one or more conductors in the middle are darker in color than the outer layer of aluminum wire, then it is a steel-core aluminum stranded wire, and the cross-section colors of the aluminum stranded wires are all the same. of.
2. Distinguish from the softness and hardness of the wires
Because there are steel wires inside, the overall hardness of steel-core aluminum stranded wire is much stronger than that of aluminum stranded wire.
3. Distinguish from the weight of the conductor
Steel-core aluminum stranded wire has steel wires inside. As we all know, steel is heavier than aluminum, so it can also be distinguished by weighing.
4. Differences in models
Steel core aluminum stranded wire, referred to as "LGJ", is made of stranded aluminum wires and steel wires. It is mainly suitable for overhead transmission lines. The inside of the steel-core aluminum stranded wire is a steel "core", and the outside is made of aluminum wire twisted around the steel core; the steel core mainly plays the role of increasing strength, and the aluminum stranded wire mainly plays the role of transmitting electrical energy. Both are bare conductors and have basically the same purpose, but their models and specifications are expressed in different ways.
Ordinary aluminum stranded wire models are represented by "LJ" and are bare conductors. At present, steel-core aluminum stranded wire (LGJ) is commonly used in China as conductors. The steel core mainly plays the role of increasing strength, and the aluminum stranded wire mainly plays the role of transmitting electrical energy. Depending on the voltage, the conductor cross-sectional area also differs. For example: Currently, LGJ-400/35 wires are generally used in 500 kV transmission lines. Among them, L is the abbreviation of aluminum wire, G is the abbreviation of steel core, J is the abbreviation of stranded wire, 400 is aluminum 400 square millimeters, and 35 is steel 35 square millimeters.
5. Main uses
Steel core aluminum stranded wire is a reinforced conductor in which single or multi-layer aluminum stranded wires are stranded outside a galvanized steel core wire. Mainly used in the power and transmission line industries.
