Learn about 1 core wire
To better understand single-core conductors, it is first necessary to understand the nature of “electrical wires”. The term electric wire refers to civil electrical conductors with transmission voltages up to 450/750V. This term has a different meaning than “electrical cable”, the reason being that both electrical wires and cables have single-core conductors, it will be confusing for many people.
You can learn the difference between electrical wires and cables . Thus, within the scope of this article, SUNWON will help customers learn about the 1-core line of wire used for civil power networks with a quote.
Single-core electric wire is a wire with a conductive core, used to transmit electricity to the civil power network with a maximum voltage of 450/750V. Single-core conductor has a structure including:
- Pure copper conductor. There are two types of conductors: rigid (solid) and braided. Hard yarn has only 1 copper thread with diameter from 0.8mm, braided yarn consists of many copper wires braided together, each strand is very small (only from 0.18mm).
- The core is covered with PVC insulation.
