Mechanical features

Mechanical features

Junction box and connector

The large junction box of the 4-pole alternator makes the connecting or rewiring of the AVR easy. Current transformers or other optional modules can also be installed in the box.

Insulation and protection

H-class insulation. The protection of the standard winding can accept up to 95% relative humidity. For particularly harsh environments, special covering protection is recommended. IP23 standard protection.

Balance

All rotors are dynamically balanced in strict accordance with the requirements of the ISO1940 standard.

Bearings

All series of 4-pole alternators adopt long-term sealed bearings.
