ACSS Cable

ACSS-cable

ACSS Conductor is a type of HTLS conductor. It is primarily used for overhead distribution and transmission lines. It is designed for continuous operation at temperatures up to 250°C without loss of strength. Under electrical load, it sags less than comparable ACSR. Moreover, its final sag is not affected by the long-term creep of aluminum. These points make ACSR particularly useful in reconstruction. In new overhead line applications, structural savings and increased current carrying capacity are possible due to reduced conductor sag.

ACSS Conductor Specifications

ACSS cable is a composite concentric stranded wire. It consists of a round aluminum 1350-O wire and a round coated steel core. The steel core carries most or all of the mechanical load of the conductor. The steel core wire is coated with a zinc-5% aluminum-mixed rare earth alloy layer to prevent corrosion. We can customize corrosion protection to suit your actual conductor exposure environment.

HTLS Conductor Manufactured by ZMS are Characterized by

overhead transmission line

ACSS conductors manufactured by ZMS have extensive experience in both material and conductor stretching. The conductor advantages are suitable for applications such as: re-conductor applications where increased current is required under existing tension and clearance conditions; new line applications where structural savings can be realized due to reduced conductor sag; new line applications where high contingency loads are required; and lines with vibration-loving problems.

Selecting the Right ACSS Conductor

If you are confused about the construction and materials used in the selection of ACSS conductors, for example, you may be torn between ACSS conductors and the common overhead ACSR conductors, please feel free to consult with the cable professionals at ZMS.

Bare-Conductor-ACSR

Aluminum-core steel-reinforced cable (ACSR) is a high-capacity, high-strength stranded conductor typically used for overhead power lines. The outer strand is high-purity aluminum, selected for its good electrical conductivity, lightweight, low cost, corrosion resistance, and good resistance to mechanical stress. Steel also has low elastic and inelastic deformation due to low coefficients of thermal expansion under mechanical loads (e.g. wind and ice) as well as current loads. These properties make ACSR sag significantly less than all aluminum conductors.

ACSR cables still depend on the tensile strength of aluminum, which is only reinforced by steel. As a result, their continuous operating temperature is limited to 75 °C, which is the temperature at which aluminum begins to anneal and soften over time. Cables that rely entirely on steel for their strength and can therefore be used at temperatures up to 250°C are called Aluminum Conductor Steel Support (ACSS).

Common High-Temperature Low Sag Arc Conductors Include

Today’s increased demand for electricity, the increasing difficulty of erecting the line corridors required for new overhead lines, and the rapid rise of renewable energy generation. There is an urgent need for transmission upgrades and transmission expansion. High-temperature low sag conductors (HTLS conductors) are a new technology for upgrading transmission lines to increase the thermal rating to improve transmission capacity. HTLS conductors can operate at high temperatures (100 °C and above) for extended periods without significant deterioration in tensile strength or other mechanical, electrical, or chemical properties. The tensile length at the same temperature is significantly lower than that of conventional aluminum or steel core aluminum conductors.
