ADSS架空室外光缆

Description

Actual situation of overhead power line is takes full consideration when ADSS cable is being designed, Suitable for different grade overhead power line. Polyethylene (PE) can be used for power lines with space potential not greater than 12KV. For overhead power lines above 110 KV (or space potential greater than 12 KV), the cable hanging point must be determined by calculating the distribution of electric field intensity, and electrical resistance (AT) jacket is applied. The dedicate design of aramid quality and stranding process can satisfy the demａnd on various spans.

Fiber

SM: G652D、G655、G657 Or other single-mode optical fibers.
MM: A1a、A1b Or other multi-mode fibers.

Jacket

Materials: electrical indentation (ATT), flame retardant polyethylene (ZRPE) or other materials.
Color: black or other colors.

Features

Application

Suitable for non-self-supporting aerial of power line.

Characteristic

Can be installed without shutting off the power; good AT performance, Good electrocorrosionperformance. Light weight and small diameter reducing the load caused by ice and wind and the load on tower and back props.Large span, span up to 500 meters; Aramid Yarn Armored process with Precision Control, The tensile ability of the cable is greatly improved. The precise control of fiber residual length and cable stranded pitch ensures the good performance of tensile strength and temperature. The design life span is 30 years.
