HTLS Conductor Cables — ACSS Cable
ZMS Cables manufactures a wide range of cables with high-temperature, low-sag conductor(HTLS Conductor) materials. Including: ACSS and ACSS/TW, G(Z)TACSR, Invar Conductor types, ACCR, ACCC Conductors, etc.
ACSS is an HTLS Conductor cable. 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.
Aluminum Conductor Steel Supported – ACSS Cable
ACSS 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 Cables Manufactured by ZMS are Characterized by
- Low conductor arc sag at high temperatures, high return temperatures, and low resistance.
- Replacement of conventional conductors without or with minor adjustments to steel tower structures or line corridors.
- Significantly increases the load capacity of transmission lines.
- Applications in transmission capacity increase where conductor strength loss (thermal limiting) and exceeding clearance limits (gap limiting) are considered, and conductor temperature is limited to a certain temperature.
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.
