In this article, we turn our attention to the introduction of wires and the differences between them. We invite you to stay with us to acquire more information in this regard.
What is a Wire?
A wire is a tool used to create connections in circuits and is responsible for transmitting electrical energy.
However, wires don’t just serve this purpose; some types of wires are also used for data transmission.
Gaining knowledge about various types of wires and increasing expertise in this field can be crucial for electricians. Why is understanding the types of wires important for building electricians?
In every building wiring project, electricians deal with various electrical equipment, with their common feature being the connection through wires and cables.
From lighting systems and wiring to telephone connection sockets, video intercoms, and fire alarm systems, all are connected through wires. These connecting devices can differ in terms of diameter, number of strands, and other features. You can read more about industrial electricity and its applications [here](link).
Features of Electrical Wires in Building Wiring
When the topic of wires is brought up, the first thing that comes to mind for everyone is building wiring.
Electrical wires used in building wiring generally share two common features. Firstly, all these wires have a plastic insulation covering, and secondly, these wires are either made of copper or have a copper-coated aluminum coating. However, it’s possible for grounding wires to have an insulating body and be more like a single-strand rather than a bundle of strands.
Typically, household wiring includes multiple strands with phase wires and one neutral wire.
Types of Wires Structurally
Wires can be categorized structurally into three main groups: stranded or single-strand wires, bundled or multi-strand wires, and combination cables of stranded/bundled wires.
Stranded Wires: Features and Applications
Stranded wires refer to single-strand wires, typically consisting of one relatively thick strand with a high diameter. Depending on the material and diameter, these wires can be used for various purposes. They are usually covered with a single layer of insulation. Key features of this category include high durability, cost-effectiveness, and resistance to oxidation.
Bundled Wires: Characteristics and Applications
Bundled or multi-strand wires, contrary to stranded wires, are composed of several thin or hair-like strands of copper. They can be found in various diameters. These wires exist both as individual strands and in cable form with multiple layers of insulation. Characteristics of this category include flexibility, high cost, increased strength, and reduced risk of breakage.
Combination of Stranded/Bundled Wires: What Are They?
As the name suggests, these products visually resemble bundled wires but share more similarities with stranded wires in terms of features. Wires in this category have fewer strands compared to bundled wires and are formed by combining multiple stranded wires.
In summary, understanding the structural differences between these wire types is essential for making informed choices based on specific applications and requirements.
Types of Wires Based on Usage
Wires come in various types based on their applications. Some notable examples include:
1. Power Wiring Wires:
These wires are single-strand and are found in various diameters. They are installed inside conduit pipes within the walls, providing electricity to your building.
2. Multi-Core Cables:
Multi-core cables are available in different types. For instance, power transmission cables from pole to pole fall into this category. Also, cables with two or more cores used for making mobile wires are part of this group.
3. Telephone Wires:
Telephone wires are divided into two categories: 2-core and 4-core wires, each available in stranded and bundled forms.
4. Data or Data Cables:
Data cables are composed of 4, 6, 8, or 16 wire strands twisted together. These strands are typically made of copper and the number is determined by the intended use. This type is commonly used in creating computer networks, installing IP surveillance cameras, and video doorbells.
5. Coaxial Cables:
Coaxial cables are employed for radio and visual communications transmitted through radio waves. Due to their structure, they are vulnerable to interference. These cables have a central copper stranded wire covered with foam insulation. The second layer, usually made of aluminum, has a multi-strand configuration. The entire cable is then covered with a plastic sheath.
Understanding the specific applications and characteristics of these wire types is crucial for making informed decisions in various electrical scenarios.
Heat-Resistant Cables:
Heat-resistant cables possess various capabilities. The coverings of these cables are made of non-flammable material, making them suitable for heat-producing devices such as various types of irons, hairdryers, straighteners, and even air conditioners.
Wire Naming and its Types
To name wires and cables, they have assigned letters to components such as insulation type, conductor material, and conductor shape. When combined, these letters precisely indicate the type of wire or cable and its intended use.
The assigned letters include:
– N: Indicates softened copper wire or, in other words, wire made according to the VDE German standard.
– Y: PVC insulation around each strand.
– S and Z: Marks for special wires.
– F: Marks for flexible wires.
– A: For wires used inside pipes.
– M: Signifying wires resistant to moisture.
Here are some examples of commonly used wires:
– Single-strand wire with plastic coating for building wiring (NYA).
– Stranded wire with plastic coating for building wiring (NYAF).
– Special wire with plastic coating for building wiring (NSYA).
– Moisture-resistant wire (NYM).
– Wire with plastic coating for lighting and household appliances (NYZ).
– Wire for chandeliers and lamps (NYFA).
– Two-core wire for lighting (NYFAZ).
– Communication and news wire (Y).
– Coaxial cable (T).
