The AMKA System is a reliable, safe and easy way to build Low Voltage Overhead Line System. Thanks to few components and short poles it is very favorable to build. AMKA is used e.g. in Finland, Estonia, Hungary, Russia and Turkey.
The uninsulated messenger cable consists of one to five black, weather resistant polyethylene insulated conductors (high density or cross-linked). The conductors are twisted around a bare aluminium alloy messenger (tensile strength 300 N/mm²).
The messenger, which is also a neutral conductor, takes all mechanical load. The cross-section of the main phase conductors can vary from 16 to 150 mm²to suit network’s load currents, maximum acceptable voltage drop and short circuit currents.
The 16-95 mm² size of the messenger (neutral conductor), depends on mechanical and electrical conditions. The cable can be supplied with one or two insulated conductors for street lighting. Ensto offers a complete product package for AMKA System.
