ADSS self supporting fiber optical cable

Model Number: ADSS

Type: Dielectric

Fiber Number: 4~288

Installation Application: Aerial Self-supporting


Product Description:

Central Strength Member:

Fiberglass reinforced plastic (FRP)

Inner Jacket:

Black UV and waterproof polyethylene (PE).

Strength Member:
Dupon Kevlar Yarn

Outer Jacket:

-For overhead power lines<110kV,PE outer jacket is applied. For power lines≥110kV,AT outer jacket is applied.

- Span<100m,single jacket is applied . Span ≥100m,.double jackets are applied

Span:

50m to 800m


Features:

Can be installed without shutting off the power.

Excellent AT performance. The maximum inductive at the operating point of AT jacket can reach 25kV.

Light weight and small diameter reducing the load caused by ice and wind and the load on towers and backprops.

Large span lengths and the largest span is over 800m.

Good performance of tensile strength and temperature.

The design life span is over 30 years.

Applications:

The actual status of overhead power lines is taken into full consideration when ADSS cable is being designed.

For overhead power lines under 110kV, PE outer sheath is applied.

For power lines equal to or over 110kV, AT outer sheath is applied.

Note: Only a part of ADSS cables are listed in the table. ADSS cables with other spans can be inquired from us directly.

Specifications in the table are got on condition that there is no height difference and the installation sag is 1 %.

Fiber count is 2 to 72. The identification of fibers complies with the national standard.

This datasheet can only be a reference, but not a supplement to the contract. Please contact our sales people for more detailed information.

We can also produce adss cable with single jacket with cheaper price ,and the span is up to 120m.
