Mark AS denotes an airmail, non-insulated wire consisting of aluminum wires and steel core. Aluminum provides excellent conductivity and low weight, and steel - high strength and resistance to stretching. It is this combination that makes an uninsulated wire ideal choice for air transmission lines (power transmission lines), especially in difficult climatic conditions.
The Injening Center offers a wide range of non-inorized wires of the AC brand suitable for various areas of use and voltage levels.
Design
The AC wire consists of aluminum wires twisted around a durable steel core. The alternation of the direction of twisting of each layer ensures the stability of the structure to mechanical loads and vibrations. This is an important advantage of operation in regions with strong wind loads and temperature changes.
Technical characteristics
-
The operating temperature range: from −60 ° C to +40 ° C;
-
The long-term permissible heating temperature of the core: up to +90 ° C;
-
Service Up: Up to 45 years;
-
Expanding force: depends on the size of the size, from 6 to 50 kN;
-
The specific resistance of aluminum: ≤0.0283 Ohm · mm²/m at 20 ° C.
AC wires from the Injenering center undergo strict control at each stage of production and provide stable electrical parameters throughout the service life.
Scope
Invalid wires of the AC are used:
-
in distribution and main power lines;
-
In areas with a moderate and cold climate;
-
in areas with large spans between supports;
-
in conditions of high wind and ice loads.
The Injening Center supplies AC wires designed for use in networks with a voltage of up to 500 kV, including for industrial facilities, power plants and substations.
Invalued wires of the AC brand-this is a reliable, strong and economically effective solution for air transmission lines. Thanks to strong steel
