National Grid Power Generating AAC Conductor All Aluminum Conductor
AAC All Aluminum Conductor
AAC–ASTM-B All Aluminium Conductor
AAC are a refined Aluminium stranded conductor with a minimum metal
purity of 99.7%. It is principally used in urban areas where
spacing is short and the supports are close. It can be used in
coastal regions owing to its high degree of corrosion resistance
and is also used extensively within the Railway and Metro
Conductor (AAC and ACSR) 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
valleys and the places where special geographical features exist.
2. Service Performance
(1).The permissible long-time operating temperature for aerial
conductor is 70oC.
(2).Under the circumstance that rare climate occurs and high ice
coverage rate, 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 installed, the
connecting tube should be painted by moisture-proof varnish in
order to protect it from corrosion.
(4).Under installation, 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.
We can supply this conductor according to different recognized
standards, such as IEC61089, BS215, BS EN 50182: 2001, STM B231,
CSA C49, DIN480201, JIS C3109, customer special specification also
can be satisfied.
