Three learning paths
Where should we start?
Depending on whether you want to read, take a course or just get a quick answer, choose one of these three paths.
Suggested paths
Reading and learning order
For each field, an order of courses and articles is suggested so you don't lose your way.
Wire and cable
Get to know optical cable construction and installation considerations; then continue with the power wire and cable articles along the same path.
Solar energy
Start with system components and explore the proposed solar power design curriculum.
New and practical
The most useful articles
شناخت تفاوت مس، آلومینیوم و CCA، عایق و روکش، PVC و XLPE و مدارک لازم برای بررسی ادعاهای فنی کابل.
تفاوت طول مسیر، متر سیم و متر کابل، کاربرگ متراژ، اضافه‌طول اتصال و تبدیل مقدار پروژه به سفارش حلقه یا قرقره.
انتخاب سیم و کابل براساس نوع پروژه، بار، سطح مقطع، مسیر نصب، مواد، افت ولتاژ و مقدار سفارش؛ همراه مسیر مطالعه و دسته‌های مرتبط.
A cable's current capacity does not come from the cross-section alone. Check the conductor material, insulation, installation method, ambient temperature and the grouping of circuits together with the reference table.
Who is it for?
Anyone who works with wire and cable
Buyers and clients
Learn which documents to ask for when comparing prices and choosing a model.
Contractors and installers
Review installation considerations, voltage drop and current capacity before ordering.
Electricians and technicians

Frequently asked questions
About Barad Academy
What is Barad Academy?
It is a collection of articles, workshops and technical guides that the Barad team publishes to help with choosing and correctly using wire, cable and communication equipment.
Does this content replace engineering advice?
No. The content is educational. The final calculation for each project must be done with the technical lead, that model's documents and the project's requirements.
How are the workshops held?
The curricula are proposed outlines. The schedule, fees and format are agreed with Barad before registration.
What sources are the articles written from?
Each article lists its reference sources at the end so you can look into the topic independently.
Your question isn't covered by these paths?
Tell us the product name or code, the application and the project conditions so we can review them together.
