In the world of electrical distribution, ensure reliability, Security and efficiency of your network is of utmost importance. One of the key components that contribute to the proper functioning of these systems is the pre-assembled cable. Pre-assembled cables have become an essential part of modern infrastructure due to their durability, ease of installation and ability to minimize electrical losses. In this article, We will explore the different types of pre-assembled cables available, including 2 pre-assembled cable×25, preassembled cable 2×16, preassembled cable 2×6, single-phase pre-assembled cable, three-phase pre-assembled cable, and more.
Whether you are looking to improve your residential electrical systems, commercial or industrial, Knowing the differences between each type of pre-assembled cable will help you make informed decisions that ensure the security and efficiency of your network..
What is preassembled cable?
Pre-assembled cables are electrical cables made with pre-insulated conductors that are grouped into a single unit.. This configuration reduces the amount of manual assembly required during installation, providing a cost-effective and time-saving solution to electricians and engineers.
The biggest advantage of pre-assembled cables is that they come ready for installation, which reduces the risks of error and possible failures. These cables are usually made of aluminum or copper and are designed to withstand harsh environmental conditions., making them ideal for overhead power lines.
Pre-assembled cable types
There are several types of pre-assembled cables, each suitable for specific applications. Below are some of the most common types:
1.Cable Preassembled 2×25
One of the most used types of preassembled cables is the preassembled cable 2×25. This cable consists of two conductors with a cross section of 25 mm² each, usually aluminum, and is commonly used in low voltage overhead networks. Thanks to its robust design, It is perfect for distributing electricity to residential areas and small businesses. Offers excellent electrical conductivity and durability, so it is suitable for long distance electrical transmission.
Applications:
Residential and commercial electrical distribution
Low voltage overhead lines
Rural and urban electrification
Main advantages:
High durability and resistance
Easier installation compared to non-preassembled cables
Excellent electrical conductivity
2.Preassembled cable 2×16
The pre-assembled cable 2×16 It is another popular option in electrical installations. With two conductors 16 mm² each, this cable is slightly smaller than version 2×25, but still very effective for low voltage applications. Its smaller size makes it ideal for areas with lower electrical demand or for shorter distribution distances..
Applications:
Small residential buildings
Low voltage distribution systems
Public lighting networks
Main advantages:
Cost effective for small installations
Easy to manage and install
Suitable for areas with lower energy consumption
3.Preassembled cable 2×6
For even smaller electrical loads, the pre-assembled cable 2×6 it is the best option. With drivers 6 mm², This cable is typically used for low power applications, such as connecting individual homes or powering smaller devices on a power grid.
Applications:
Small individual household connections
Street and garden lighting
Low demand electrical installations
Main advantages:
Economical for small scale projects
Light and easy to transport
Simple installation with a minimum of tools
Single-phase Preassembled Cables vs.. Three-phase
Another key distinction when selecting the appropriate cable pre-assembly is whether your system requires a single-phase or three-phase cable configuration..
Single-phase preassembled cables
Single phase pre-assembled cable is used in single phase electrical systems, Typically found in most homes and smaller commercial facilities. Single-phase power refers to the distribution of alternating current electrical power (CA) in which all supply voltages vary in unison.
This type of cable is designed to carry single-phase electricity, making it ideal for residential buildings where energy demand is relatively low.
Applications:
Residential housing
Small offices and companies
Low energy consumption appliances
Three-phase preassembled cables
Instead, Three-phase pre-assembled cable is designed for three-phase electrical systems, Commonly used in larger industrial and commercial environments. Three-phase power is more efficient for high-power machinery and long-distance electricity distribution. The three-phase configuration consists of three conductors and is used to balance loads, making it ideal for high power applications.
Applications:
Industrial facilities
Large commercial buildings
High power machinery and equipment
Materials: Aluminum vs. Copper Pre-Assembled Cables
When choosing a preassembled cable, It is important to take into account the material used for the conductors. The most common materials are aluminum and copper, each with its own advantages.
Preassembled aluminum cables
Pre-assembled aluminum cables are popular for their lightness and cost-effectiveness. Although aluminum is not as conductive as copper, It is significantly lighter and more affordable, making it a great option for large scale installations where weight and cost are major concerns.
Advantages of aluminum:
Lower cost than copper
lighter, easy to handle and install
Sufficient conductivity for most residential and commercial applications
Preassembled Copper Cables
Copper is known for its excellent conductivity and is the preferred choice for high power applications where electrical losses need to be minimized.. However, copper is more expensive and heavier than aluminum, which can increase installation and material costs.
Advantages of copper:
Superior conductivity
Better performance in high demand environments
Longer life and corrosion resistance
Where to buy pre-assembled cables?
For those looking to purchase pre-assembled cables, a popular option is Sodimac. Sodimac offers a wide variety of pre-assembled cable options, including 2 pre-assembled cables×25. Its range of cables ensures that customers can find the right product for their specific electrical needs., whether residential, commercial or industrial.
Factors Influencing Preassembled Cable Prices
One of the key considerations when purchasing pre-assembled cable is price. Several factors can affect the cost of these cables, including size of conductors, the material used and the type of insulation.
1.Driver size
The larger the size of the conductor, the more expensive the cable will be. For example, a pre-assembled cable 2×25 will be more expensive than a pre-assembled cable 2×6 due to the larger cross section of the conductor, which allows it to carry more current.
2.Material
As already mentioned, aluminum is more affordable than copper. Therefore, Aluminum pre-assembled cables tend to be less expensive than their copper counterparts.
3.Insulation type
The highest quality insulation materials that offer greater heat resistance, Humidity and other environmental factors can also increase the price of pre-assembled cable. It is important to choose a cable with the proper insulation for your specific application to ensure long-term performance and safety..
Instalation and maintenance
One of the main advantages of pre-assembled cable is its ease of installation. Since the cables come pre-assembled, The installation process is faster and easier compared to traditional cables. This reduces labor costs and minimizes the likelihood of installation errors..
Maintenance is also simplified thanks to durable insulation that protects conductors from environmental damage.. Even so, Routine inspections should be performed to ensure cables are in good condition, but the need for major repairs is usually kept to a minimum.
Conclusion
Pre-assembled cable is an essential component in modern electrical distribution systems, offering significant advantages in terms of installation efficiency, safety and performance. Whether you are working on a residential project or a large industrial facility, Choosing the right type of pre-assembled cable is crucial to ensuring the reliability and effectiveness of your network.
