Cableizer is a web-based software platform designed for thermal rating (ampacity) calculations of power cables. It is widely used by cable engineers, transmission planners, and renewable energy consultants to determine how much current a cable can carry without exceeding its thermal limits, under various installation conditions.
Unlike traditional spreadsheet tools or generic simulation software, Cableizer focuses on accuracy, compliance with international standards, and ease of use for both low-voltage and high-voltage AC/DC cable systems.
In major cities, utilities often cannot dig up streets to install larger cables. Using Cableizer software, engineers analyze existing duct banks and determine if fresh air circulation, water cooling, or simply recalculating with accurate soil resistivities can add 15-20% capacity without new construction.
Most users think cable rating is simply looking up a table. In reality, Cableizer software solves iteratively. Here’s a simplified algorithm:
| Section | Function | |---------|----------| | Project Tree | Manage cables, soils, installations, load cases | | Canvas | 2D cross-section viewer (scale, drag, measure) | | Property Panel | Edit selected object parameters | | Analysis Dashboard | Run calculations, view results (tables/graphs) |
