All-dielectric self-supporting cable

ADSS cables are loose-sleeved with a 250μm fiber sleeved into a loose tube made of high-modulus material filled with a waterproof compound. The loose tube (and filler rope) are twisted around a non-metallic central reinforcing core (FRP) to form a compact core, and the gaps in the core are filled with water-blocking paste. The core is extruded into a polyethylene (PE) inner sheath, then stranded with a reinforcing aramid, and finally a polyethylene (PE) outer sheath or an AT-resistant (AT) outer sheath.

Description

Product Applications

The design of YOFC ADSS fiber optic cable fully considers the actual situation of power lines, and is suitable for different levels of high-voltage transmission lines. Polyethylene (PE) sheath is available for 10kV and 35kV power lines; For 110 kV and 220 kV power lines, cable anchorages must be determined by calculating the electric field strength distribution and using an AT-resistant outer sheath. At the same time, the dosage of aramid and the perfect stranding process are carefully designed to meet the application requirements of different spans.

Product standards

YOFC’s ADSS cables comply with IEEE 1222 technical standards and comply with IEC 60794-1 standards.

Features:

• Can be erected without power supply

• AT sheath for superior tracking resistance

• Light weight and small cable diameter reduce ice and wind influences and loads on towers and supports

• Large span, the maximum span is more than 1000 meters

• Excellent tensile properties and temperature characteristics

• Life expectancy greater than 30 years
