Free AutoCAD gas-insulated switchgear, alarm and installation symbols (DWG), IEC 60617 style

About IEC 60617

IEC 60617 is the international standard for graphical symbols for diagrams, in many parts. This library holds figures from the standard's database that carry no part number, are new in the current edition and are missing from the other IEC 60617 libraries of this site, drawn after the database.

These symbols are our own drawings after the figures of the standard. They are not copied from it, and the library is not certified against it. Check them against the standard, your company standard or your customer’s legend before you decide to use a symbol.

Frequently asked questions

Where are the common switches, sockets and luminaires?

Ordinary switches, push-buttons, sockets and lighting outlets of installation diagrams are in the library “Common electrical symbols (IEC 60617)”. This library adds the newer ones: multi-gang and dimmer switches, single-phase and three-phase sockets, detectors, alarms and network devices.

Where are the other IEC 60617 symbols?

The standard is spread over several libraries on this site: common electrical symbols, power system single-line, semiconductors and tubes, binary logic elements, logic functions and analogue, telephone and sound, telecom transmission, relays and protection, machines and meters, and busbar trunking with cable television. Every library page lists the others.

Can I use the symbols in commercial projects?

Yes. They are free to use and modify in your own projects, including commercial ones. They are provided as is, without warranty.

Do the gas-insulated switchgear symbols include the enclosure lines?

Yes. The standard shows them as context lines; each block draws the enclosure and the conductor as plain lines of one length, so the symbol reads on its own. Trim or extend them to your run.

Can I change a symbol or add attributes?

Yes. Open the DWG, edit a block with BEDIT to change it or add attributes, and save. To update drawings that already contain the block, run ATTSYNC or replace the block. Make a backup first: attribute values can be lost if ATTSYNC is used carelessly.

Where do I find a ready-made set of these symbols for AutoCAD?

AutoCAD itself ships only a small set of sample blocks, so a full symbol set has to come from a library. Download the ZIP on this page and open the DWG: every symbol is a block. Insert one with INSERT (Blocks palette, Libraries tab, then pick the DWG) or drag it from DesignCenter (ADCENTER). You can also download a single symbol on its own.
