HTLS Conductor Cables

High Temperature Low Sag (HTLS) Conductor Cables

SiTong Cable Cables manufactures a variety of cables with high temperature low sag conductor materials - HTLS conductors. These include ACSS and ACSS/TW, G(Z)TACSR, Invar conductor types, ACCR, ACCC conductors, etc.

Features of HTLS Conductor Cables

1. Low conductor arc sag at high temperatures, high return temperature, and low resistance.
2. No or only minor adjustments to steel tower structures or line corridors are required to replace conventional conductors.
3. Significantly increases the load capacity of the transmission line.
4. Application of increased transmission capacity when considering conductor strength loss (thermal limiting) and exceeding clearance limits (gap limiting), and conductor temperature is limited to a certain temperature.

HTLS Conductor Types

• ACSS Conductor: Annealed aluminum stranded wire + conventional steel core, working temperature up to 250°C.
• G(Z)TACSR: Gap-type steel core heat resistant aluminum alloy conductor, operating temperature up to 150°C.
• Invar Conductor: Invar steel reinforced aluminum alloy conductor, 210°C.
• ACCR: Aluminum Conductor Composite Reinforced, continuous working temperature 210°C, short time 240°C.
• ACCC: Aluminum Conductor Composite Core, continuous operating temperature 180°C.

Technical Characteristics

• ACSS is commonly used for overhead transmission and distribution lines.
• Can work continuously at temperatures up to 250°C without losing its strength.
• Under electrical loads, ACSS has a lower sag strength than comparable ACSR.
• Self-damping if pre-stretched during installation.

Service

• Professional customer service for selecting the right cable product.
• One-stop project solution services and fast product delivery solutions.

Packaging

• Provided in wooden rolls, corrugated cartons, and reels.
• Cable ends are sealed with BOPP self-adhesive tape and non-hygroscopic sealing caps.
