High quality pure copper and aluminum wire overhead insulated cable
is easy to bend, convenient to install and low cost
Introduction:
Aluminum overhead insulated cable is an overhead wire with an
insulating layer and protective sheath. It uses a special cable
similar to the production process of cross-linked cables. It is a
new transmission method between overhead wires and underground
cables.
Compared with underground cables, although overhead cables are more
susceptible to external influences, are not safe enough, and are
not beautiful, they are easier to erect, with high power supply
reliability, good power supply stability, convenient installation
and maintenance, and reasonable economy. It is still widely used in
places far away from signal towers, where the number of users is
small and changes are large, and it is difficult to lay underground
cables.
Overhead cables are generally single-core cables. According to
their structure, they can be divided into hard aluminum wire
structure, hard drawn copper wire structure, aluminum alloy wire
structure, steel core or aluminum alloy core support structure, and
self-supporting three-core grain structure (wire core Can be hard
aluminum or hard copper wire) etc.
