Austrian Power Grid

The company employs a total workforce of several thousand. The mechanical locking technology for all locations is supplied exclusively by EVVA. Just over 3,700 3KSplus mechanical lock cylinders have been installed with a total of 1,100 master and submaster keys, over 1,000 individual keys and around 540 Combi keys. The mechanical system operates without springs and uses milled curves that are encoded a total of four times during one locking process. The system is also exceptionally wear-resistant and protected against lock picking. Its advantage lies in the high number of possible variations for such complex locking systems with overlapping hierarchies. Inserted either way round, the reversible key opens mechanically or electronically locked doors it is authorised to unlock.

This object was realised with the locking system 3KSplus, which corresponds to today's 4KS locking system.
