Reading the square table of cable specifications and models can be a daunting task for those who are not familiar with the terminology and layout. However, with a little guidance, anyone can learn how to decipher this important document. In this article, we will provide a detailed explanation of how to read the square table of cable specifications and models from four different aspects.

1. Understanding the Terminology

The first step in reading the square table is understanding the terminology used in it. The table usually includes columns such as "Model Number," "Cable Type," "Conductor Material," "Insulation Material," "Jacket Material," and so on. Each column represents a specific characteristic or property of the cable.

To read these specifications correctly, you need to know what each term means. For example, model number refers to a unique identifier assigned by manufacturers to differentiate between different cables they produce. Cable type indicates whether it is an optical fiber or copper cable.

By familiarizing yourself with these terms, you will be able to understand what each specification represents and make informed decisions when selecting cables for your projects.

2. Decoding Cable Specifications

The second aspect involves decoding the actual values provided in each column of the square table. This requires understanding units of measurement used for various properties such as diameter, weight per unit length (e.g., pounds per foot), electrical resistance (e.g., ohms), etc.

For example, if you see a value like 24 AWG under conductor material column, it means that American Wire Gauge system is being used to measure wire thickness - lower numbers indicate thicker wires while higher numbers indicate thinner wires.

In addition to numerical values, some columns may also include codes or abbreviations that represent specific characteristics or features of cables such as flame retardancy (FR), low smoke zero halogen (LSZH), etc.

3. Comparing Different Models

The third aspect involves comparing different models listed in the square table based on their specifications. This allows you to identify similarities and differences between various cables available in order to choose one that best suits your requirements.

You can compare parameters like conductor material - copper vs aluminum; insulation material - PVC vs polyethylene; jacket material - PVC vs LSZH; maximum operating temperature; maximum voltage rating; etc., among different models listed in separate rows within the same column(s).

This comparison helps you narrow down your options by eliminating those cables that do not meet your project's specific needs.

4 Analyzing Additional Information

In addition to basic specifications mentioned above，the square table may also contain additional information about each model，such as its application areas，installation methods，and certifications.

This information provides valuable insights into where and how each cable should be used.For example,a certain model might be suitable for outdoor installations while another might be better suited for indoor use.

Certifications like UL（Underwriters Laboratories）or RoHS（Restrictionof Hazardous Substances Directive）indicate compliance with industry standards.

Analyzing this additional information helps ensure that you select appropriate cables based on factors beyond just technical specifications.
