Предварительно установленный Алюминиевый кабель 3x50 1x50 1x25 мм2 Aislacion de XLPE

Applications
Used to supply 3 phase power, usually from a pole- mounted transformer, to the user's service head where connection to the service entrance cable is made. To be used at voltages of 600 volts or less phase to phase and at conductor temperatures not to exceed 75°C for polyethylene insulated conductors or 90°C for cross linked polyethylene (XLPE) insulated conductors.

Construction
Conductors are concentrically stranded, compressed 1350-H19 aluminum. Insulated with either polyethylene or XLP cross linked polyethylene. Neutral messengers are concentrically stranded 6201, AAC, or ACSR. One conductor is manufactured with an extruded ridge for phase identification.
