AMKA Cable

AMKA Cable Description

AMKA cables use insulated aluminum phase conductors tightly wound around a central aluminum alloy crossbeam, which serves as both the neutral and support conductor. Designed for outdoor pole mounting, it is also suitable for ground connections on buildings. Even when exposed to sunlight, humidity, high temperatures, frost, or a combination thereof, it can be stored outdoors unshaded for up to 5 years without electrical or mechanical degradation.
