Jklyj 1kV / 10kV overhead insulated cable anti-aging special aluminum core overhead wire for rural reconstruction
Overhead cable (full name: overhead insulation > cable) is an
overhead conductor with insulating layer and protective sheath. It
is a special cable manufactured by a production process similar to
cross-linked cable. It is a new power transmission mode between
overhead conductor and underground cable. Overhead cables are
single core. According to their different structures, 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
corrugated structure (the wire core can be hard aluminum or hard
copper wire), etc. It has the main characteristics of high power
supply reliability, good power supply safety, convenient erection
and maintenance and reasonable economy. Its main technical
parameters include weather resistance, insulation level, inner and
outer semi-conductive shielding layers. Overhead cables are widely
used in power transmission at home and abroad.
