ACSR conductor has a wide range of applications. Suitable for
transmission lines of various voltage levels. AAC,AAAC,ACSR, ACAR
conductor have been widely used in power transmission lines with
various voltage levels,because they have such good characteristics
as simple structure,convenient installation and maintenance,low
cost large transmission capacity.And they are also suitable for
laying across rivers and valleys where special geographical
features exist.Construction Of ACSR ConductorThe structure of an
ACSR (Aluminum Conductor Steel Reinforced) conductor consists of a
central steel core surrounded by one or more layers of aluminum
wires. The steel core provides mechanical strength and support to
the conductor, while the aluminum wires provide electrical
conductivity.The steel core is typically made up of several
high-strength steel wires twisted together to form a single
stranded core. The number and size of the steel wires in the core
depend on the size and capacity of the ACSR conductor. The steel
wires are usually coated with a thin layer of zinc to protect them
from corrosion.The aluminum wires are stranded around the steel
core in a helical pattern, forming one or more layers. The aluminum
wires are usually made of high-purity EC-grade aluminum, which has
high conductivity and is lightweight. The number and size of the
aluminum wires in the layers also depend on the size and capacity
of the ACSR conductor.The steel core and the aluminum layers are
held together by a thin layer of grease, which helps to prevent
corrosion and minimize friction between the different components of
the conductor. The entire structure is then coated with a layer of
zinc to protect it from corrosion.Standards Of ACSR ConductorASTM -
B 230, ASTM - B 231, TS IEC 1089, DIN48201, BS 215.Service
Performance Of ACSR Conductor(1).The permissible long-time
operating temperature for aerial conductor is 70°C.(2).Under the
circumstance that rare climate is occuring and ice coverage rate
low in heavy ice area,the biggest stress of cable at the lowest
point of the sag should not exceed 60% of the short-time
destructive power.(3).When connecting conductors,the conductor
beside the connecting tube can't be prominent.Otherwise,the force
on the operating conductors will be unbalanced.After connectors are
install,the connecting tube should be painted by moisture-proof
varnish in order to protect it from corrosion.(4).Under
installaion,the arc downing stress of all the conductors should be
the same.With in the permissible distance of crossing buildings or
dropping to the ground,the stress can be 10-15% higher than regular
stress.Specifications Of ACSR ConductorNominal Area(mm2)Stranding
