ADSS Cable Single Sheath vs Double Sheath: Key Differences and How to Choose

What is ADSS cable?

ADSS (All-Dielectric Self-Supporting) cable is a non-metallic, self-supporting cable designed for overhead power lines that can withstand mechanical stress without metal reinforcements. Its core advantages include:
1.EMI-resistant ADSS cable.

2.lightweight fiber optic cable.

3.long-span ADSS cable.

Double Sheath vs Single Sheath: Structural Differences.

Ⅰ. Single Sheath ADSS Cable (Single Sheath)

Structure: Single-layer high-density polyethylene (HDPE) sheath, directly wrapping the optical fiber unit.

Features:

1. ADSS cable has lower cost

2. Lighter weight, suitable for short spans (<100 meters)

3. UV-resistant sheath

Ⅱ. Double Sheath ADSS Cable (Double Sheath)

Structure: Inner layer HDPE + outer layer anti-tracking sheath (such as AT/PE material), double protection.

Features:

1. Anti-tracking corrosion (keyword: anti-tracking ADSS cable)

2. Extreme temperature resistance (-40°C to 70°C)

3. High mechanical strength, suitable for long spans (>200 meters)

Performance Comparison: When to Choose Single or Dual Jacket?

Selection Guide for Applicable Scenarios:

Single-sheath ADSS Cable:

1. Short-span telecommunication networks

2. Dry, low-pollution environments (such as urban suburbs)

3. Projects with limited budgets

Double-sheath ADSS Cable:

1. Near high-voltage power lines (keyword: ADSS for high-voltage lines)

2. High humidity/pollution environments such as coastal areas and industrial areas

3. Extreme climate areas (strong winds, ice and snow)

F A Q

Q1: Is the double-sheath ADSS worth the extra cost?
A1: In corrosive environments or long span scenarios, the double sheath can reduce maintenance costs and avoid signal loss due to sheath aging.

Q2: How to determine whether the sheath needs to be replaced?
A2: Regularly check the surface of the sheath for cracks or electrical traces (keywords: ADSS cable maintenance).

Q3: Can single/double sheaths be mixed?
A3: Not recommended, the sheath performance must be consistent with the environmental conditions.
