IEC 60228 is the international standard for the designation of the conductor cross-section of insulated cables. In particular, a standard table for conductor cross-sections is defined as follows:
| Internationally standardized conductor cross-sections (IEC 60228) | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| 0.5 mm² | 0.75 mm² | 1 mm² | 1.5 mm² | 2.5 mm² | 4 mm² | ||||
| 6 mm² | 10 mm² | 16 mm² | 25 mm² | 35 mm² | 50 mm² | ||||
| 70 mm² | 95 mm² | 120 mm² | 150 mm² | 185 mm² | 240 mm² | ||||
| 300 mm² | 400 mm² | 500 mm² | 630 mm² | 800 mm² | 1000 mm² | ||||
In electrical engineering , the designation of the cross-section is generally more useful than that of the diameter , because the strength, mass and resistance of a cable depend on the cross-section as well as the current that the cable can carry without overheating. Minimum cross-sections are prescribed for many applications. The standard describes various aspects of the conductors of insulated cables.
Other names
The IEC 60228 is equivalent to:
- CEI 60228
- EN 60228
In Germany the standard is valid as DIN standard DIN EN 60228 or VDE 0295 .
Leader classes
The specification of the class according to IEC 60228 (DIN VDE 0295) refers to the flexibility of the conductor. A statement about the type of use does not result directly from the conductor class. While multi-wire cables are mainly used in portable installations due to their flexibility, certain fine-wire cables are only intended for fixed, immobile installation (e.g. core lines or cables in vehicle, ship and aircraft construction as well as for high-frequency applications ).
