ADSS (All-Dielectric Self-Supporting) and OPGW (Optical Ground Wire) cables are essential components in modern telecommunications and power distribution networks. To ensure the proper installation and functioning of these cables, a range of specialized accessories is required. These accessories help maintain the integrity and efficiency of the cable system, particularly in high-performance overhead installations. 

Structure and Types of ADSS/OPGW Accessories
ADSS and OPGW accessories are designed to enhance the mechanical and electrical performance of fiber optic cables in outdoor environments. These accessories are used for cable termination, suspension, grounding, and support. The following sections detail the key components of ADSS and OPGW accessories:

1. ADSS Accessories
ADSS cables are typically installed without the need for metallic components, relying on the tensile strength of dielectric materials. The main accessories used with ADSS cables include:

Suspension Clamps:
Designed to secure the cable to support structures and allow for the expansion and contraction of the cable.
Materials: Corrosion-resistant aluminum, steel, or composite materials.
Features: Adjustable to accommodate various cable diameters, with strong resistance to environmental wear.
Tension Clamps:
Used to secure the ADSS cables at the end of the span, with the ability to absorb mechanical stress.
Features: High tensile strength to hold the cable firmly under load.
End Fittings:
Used to secure the cable at the termination points, providing proper cable stress distribution.
Materials: Stainless steel or galvanized steel for corrosion resistance.
Earth Bonding Kits:
Essential for protecting the ADSS cables from lightning strikes and electrical surges by providing grounding.
Features: High conductivity and resistance to corrosion.

2. OPGW Accessories
OPGW cables combine optical fiber for communication with a metallic conductor for grounding and protection against lightning. Key accessories for OPGW cables include:

Suspension Clamps:
These are specifically designed to hold both the optical fiber and metallic conductors of OPGW cables.
Features: Adjustable tension settings to ensure correct cable positioning and tension.
Tension Clamps:
Used for maintaining the mechanical integrity of the cable under tensile stress, ensuring the OPGW cable is securely anchored at both ends of the span.
Features: Designed to prevent cable elongation and protect from excessive mechanical loads.
Splice Closures:
Used for splicing optical fibers and ensuring that the connection is protected from moisture and mechanical stress.
Features: Waterproof and pressure-resistant design.
Grounding Kits:
Critical for grounding the metallic portion of the OPGW cable to protect against electrical surges.
Features: Designed to work effectively in high-voltage environments and provide effective lightning protection.
Cable Clamps and Supports:
Provide additional support to ensure that OPGW cables maintain their shape and alignment along power line structures.

Common Product Parameters for ADSS/OPGW Accessories
Material: Stainless steel, galvanized steel, aluminum, and corrosion-resistant composites.
Mechanical Strength: Suspension and tension clamps have tensile strength ratings from 2,000 N to 15,000 N depending on the cable type and span length.
Temperature Range: Designed to operate in environments with temperatures ranging from -40°C to +70°C.
Corrosion Resistance: All accessories are treated to resist corrosion, ensuring durability in harsh weather conditions and environments with high humidity or salt exposure.
Environmental Resistance: UV resistance for plastic components, and anti-corrosive treatment for metal parts, making the accessories suitable for long-term outdoor exposure.

Applicable Scenarios
ADSS/OPGW accessories are used in a variety of applications across multiple industries, including:

Telecommunications:
ADSS/OPGW cables are often used in urban and rural telecommunication networks for high-speed internet and data transfer. Accessories ensure secure installation and longevity in harsh environments.
Power Transmission:
Used for communication and protection in power transmission systems, especially in locations where traditional ground wires are impractical. Accessories support the safe installation of cables between transmission towers.
Renewable Energy Projects:
ADSS/OPGW accessories are crucial for the integration of communication systems in solar and wind farms, where cables are often required to cover large distances and withstand extreme conditions.
Smart Cities and IoT Networks:
Essential in the creation of fiber optic backbones for smart cities and IoT systems, where OPGW cables provide both communication and safety functions along existing power lines.
