(ADSS)All-dielectric self-supporting optical cable

The ADSS optical cable adopts a loose-skinned twisted structure. 250µm optical fiber is sheathed in a loose tube made of a high modulus material, and the loose tube is filled with a waterproof compound. The loose tube (and filler rope) is twisted around a non-metallic central reinforcement core (FRP) to form a compact cable core, and the gaps in the cable core are filled with water blocking grease. The outer core of the cable is extruded with a polyethylene (PE) inner sheath, then stranded with aramid for reinforcement, and finally the extruded polyethylene (PE) outer sheath or tracking resistant (AT) outer sheath.

Product description

The ADSS optical cable adopts a loose-skinned twisted structure. 250µm optical fiber is sheathed in a loose tube made of a high modulus material, and the loose tube is filled with a waterproof compound. The loose tube (and filler rope) is twisted around a non-metallic central reinforcement core (FRP) to form a compact cable core, and the gaps in the cable core are filled with water blocking grease. The outer core of the cable is extruded with a polyethylene (PE) inner sheath, then stranded with aramid for reinforcement, and finally the extruded polyethylene (PE) outer sheath or tracking resistant (AT) outer sheath.

 

Applications

· The design of the ADSS optical cable fully considers the actual situation of the power line, and is suitable for different levels of high-voltage transmission lines. For 10 kV and 35 kV power lines, polyethylene (PE) sheaths can be used; for 110 kV and 220 kV power lines, the distribution point of the optical cable must be determined by calculating the electric field strength distribution and an outer track (AT) outer sheath. At the same time, the amount of aramid fiber and the perfect twisting process are carefully designed to meet the application requirements of different spans.

 

Product Standards

· The ADSS optical cable complies with the IEEE 1222 technical standard and complies with the IEC 60794-1 standard.

 

Features

• Uninterruptible power erection

• Adopt AT sheath, excellent resistance to tracking

• Light weight and small cable diameter reduce the impact of ice, wind and load on towers and supports

• Large span, maximum span exceeds 1000 meters

• Has excellent tensile properties and temperature characteristics

• Life expectancy is greater than 30 years
